Optical module can bring billions of dollars

one of the most popular products – fiber optic transceiver. The contract manufacturers CEM are two shiny. According to industry watchers, CEM Once you’ve mastered the complex optical interconnect technology and related accessories manufacturing technology each year will be able to win billions of dollars in revenue. Observers say that, even if the optical fiber Internet technology is still in the development phase, but it will still be the fastest growing areas in the huge market in the communications industry. “The market is very strong demand for cheap and high-quality fiber optic module.” Jon Peddie Associates analyst Jon Peddie said. The fiber-optic module is mainly used in high-bandwidth telephone lines, Internet access and other communications-related applications. During transmission of the light signal by means of a series of devices to accomplish various functions, including the signal generator, the guide, separation, regeneration, amplification, loading, Synthesis, emission, reflection and re-directing. Merrill Lynch analyst Thomas B. Astle said. “We believe that optical technology is one of the fastest growing areas in the telecom market. Estimated that in 2002, the annual growth rate of the overall market will reach 40%,” he added. Dataquest, said fiber optic transceivers reached $ 6 billion in sales revenue in 1999. Its analyst Stan Bruederly of that sales revenue will reach $ 7.6 billion this year, and will reach $ 12 billion by 2003. This demand situation has made some OEM telecommunications and networking products as well as some components suppliers, began to transfer their production of fiber optic devices to CEM technology. Nortel Networks, for example, last year, part of its own fiber optic outsourcing to SCI Systems, analysts have estimated annual revenues of $ 1.5 billion will bring SCI. However, the SCI Corporation Nortel spokesman declined to answer whether the production of fiber-optic module, or just processing for the Canadian telecommunications giant light board. He just said: “part of our optical networking products have been outsourced processing. Merrill Lynch analyst Jerry Labowitz said, another high-grade fiber-optic devices and fiber optic module manufacturer JDS Uniphase, are also being considered less complex fiber module production outsourcing to a CEM. JDS Uniphase, a major cause of the rapid development of the internal core force of aggregation, the company’s Chief Financial Officer Anthony Muller said. Another reason is that CEM has been a year ago mastered more fiber module production technology. “Technologies are relatively well-understood,” Anthony Muller said, “We are more concerned about the CEM is how do, how to train them harder and faster to meet the needs of the user.” Engaged in the optical networking business, Alcatel, Ciena network, Corning, Lucent Technologies, NEC, and Sycamore Networks, Inc.. Lucent spokesman said the company does not intend to outsourcing fiber optic transceiver  production. The company recently announced that, in order to meet the growing market demand for high-speed optical communication network devices, the company will spend $ 40 million to expand its production capacity in Southern California. “Some OEM to develop rely on the manufacture of fiber optic devices, and they do not want to do anything else.” Said Srivinas Rao, Solectron’s vice president of technology. The company is one of the world’s largest CEM. For competitive reasons, some OEM suppliers require their outsourcing the processing partner not to disclose the level and types of the production of optical devices. This is the CEM as several well-known production of Jabil Circuit, SCI and Solectron its contracted fiber optic devices do not want to talk about. Jabil’s positive efforts to become a leader in the optical components market. We hope that the optical components market in significant growth in the coming period, Jabil, a spokesman said. In the last year, CEM supplier Celestica and optical networking company Sycamore Networks signed a two-year-old contract. However, Celestica Company Chairman and Chief Executive Officer Eugene Polistuk unwilling to disclose the inside information processing for Sycamore. In addition to the production of optical devices, Celestica also two other factories to provide high-tech optical module welding services. “Polistuk said:” This is a whole new field, it has become a hot spot. ” The fiber optic module is a part of the production process of the entire processing, said Solectron’s company Rao. “It’s just being a hot chase, but does not represent the entire market.” He added. This market can be divided into three stages: the Wavelength Division Multiplexing (WDM) for WAN, LAN WDM MAN WDM. “We are in the middle of the first stage, WAN WDM is the use of fiber-optic network constructed fiber optic cable infrastructure,” Merrill Lynch Astle said, “At this stage, including the rapid development of the submarine communication system, it will solve the intercontinental bandwidth bottleneck problem. ” “The local WDM and Metro WDM market rise estimated for this year and next year, the main driving force is the ISP constantly want to build local area networks and metropolitan area networks using WDM technology,” Astle said, “We estimate that the arrival of the third stage of the between the years 2002-2004, when a full-mesh optical networks, and all light-based switching and routing. ” CEM are already prepared for this. “We are in contact with a lot of companies,” said Chairman and CEO Michael Marks of Flextronics, “We do the processing of the light board, but does not provide light welding services. Now we are to strengthen our capacity in the optical networking and user contact . “  

What are fiber optic loopback modules

Fiber Optic Loopback modules are also called optical loopback adapters. There are LC loopback modules, SC loopback modules and other types. They are designed for testing, engineering and the burn-in stage of boards or other equipment. Optical loopback adapters provide system test engineers a simple but effective way of testing the transmission capability and the receiver sensitivity of network equipment.

Fiber Optic Loopback Specifications: Insertion loss: Less than 0.2dB Exchangeability = 0.2 (500 cycle passed) Operating temperature range: Less than 0.2 dB ( -40 to +80°C) What types of Fiber loopback modules are available? The most popular types of fiber optic loopback modules are SC, LC, FC and MTRJ connector types. But each connector type is divided again by fiber type, connector polish type and attenuation. >>Fiber Types Each connector type is available for three fiber types. They are 10G OM3 50/125um multimode, OM2 50/125um multimode, OM1 62.5/125um multimode and 9/125um single mode. >>Connector Polish Types Only PC polish is available for multimode type fibers. But for single mode fiber, two connector polish types are available: UPC polish and APC polish. >>Working Wavelength In addition to fiber type, working wavelength is the other important factor for choosing the correct fiber optic loopback module for your specific application. Available wavelengths are 850nm, 1310nm and 1550nm. 850nm and 1310nm are for multimode applications and 1550nm is for single mode applications.

The core components of the fiber connector: ceramic ferrule

What is ceramic Chaxin? Ceramic ferrule’s main material ceramic. Ceramic ferrules must be used in optical fiber communication, it is a very important role to ensure the communication quality.     Fiber connection technology is divided into two categories, one is permanently connected, often called fixed joints dead joints; other is a removable activities connect, often referred to as the union, need to use the fiber optic connector. In the transmission network, a cable connection between the permanent connection, the optical fiber connector is mainly used to implement the system between devices, between the equipment and instruments, equipment and between the optical fibers and the optical fibers and optical fiber between nonpermanent the fixed connection, it is the optical communication system of the most widespread and the largest use of basic passive devices. Matching ceramic material with quartz fiber thermal, physical and chemical properties and stability, as the core device with ceramic ferrule fiber optic connectors has been developed rapidly.               The ceramic ferrule most important role is to achieve the physical docking of the optical fiber (also known as fiber cold continuation), often used in conjunction with ceramic sleeve. Ceramic cylindrical tube fired zirconia ceramic ferrule, hard texture, delicate white color accuracy of the finished sub-micron level, is the most commonly used in optical fiber communication network, the largest number of precision positioning pieces, often used for the manufacture of the optical connector, the optical coupling of the devices, and the like. Like the circuit in the plug and receptacle, the ferrule and the sleeve are the key components of optical fiber connector. The diameter of only 0.125 mm optical fiber must pass through the inner bore of the ceramic ferrule, and to maintain a linear transmission of the state; connected to the outgoing optical fiber in the other end of the ceramic ferrule. Straight and precise connection directly affect the transmission efficiency of the optical fiber. Ceramic ferrule is not only highly internal hole diameter, while the outer diameter and concentricity requirements higher. And the optical connector because of the need for multiple plug, after repeated use must maintain the same accuracy of the same, very high demands on the material density. The ceramic ferrule classification and features Ceramic ferrule in accordance Dimensions is divided into three categories of SC, LC, and non-standard, in accordance with its precision, can be divided into two kinds of single-mode and multimode. The industry is often referred to as SC singlemode ferrule, SC multimode ferrule, LC singlemode ferrule, LC multimode ferrule, non-standard mortise. The ceramic ferrule characteristics depend on the characteristics of the material zirconia, mainly reflected in the good thermal stability, high hardness, high melting point, and wear-resistant, high machining accuracy.

PON technology development history

The Passive Optical Network – PON mainly uses a passive optical power divider (coupler) for forwarding information to the respective users. As a result of the optical power splitter, so that the power reduction, and therefore more suitable for use for short-distance. PON (passive optical network) refers to ODN (optical wiring network) does not contain any electronic devices and electronic power, ODN all composed by the optical splitterand other passive components, active electronic devices without precious. A passive optical network includes a mounted on the optical line terminal (OLT) of the central control station, as well as a number of supporting the optical network units (ONUs) installed in the customer premises. The optical distribution network (ODN) between the OLT and the ONU includes optical fiber and passive optical splitters or couplers. PON technology development APON (ATM PON) 1995 FSAN (Full Service Access Network) alliance in 1996 by 13 major network operators and their equipment suppliers, 155Mb / s PON system technical specifications, ATM transport protocol, ITU-T G.983 series of standards BPON (Broadband PON) 2001, APON standard was later strengthened to support 622Mb / s transfer rate, coupled with dynamic bandwidth allocation, protection and other functions, to provide Ethernet access, video transmission, high-speed leased line business broadband PON GPON (Gigabit PON) The FSAN Union rate over 1Gb / s PON standard research, would like to propose a program can run in a higher rate, but also in terms of multi-service, OAM & P, and scalability compared to other PON efficiency high. This study makes Gigabit PON (GPON) appears. In January 2003, ITU-T approved established GPON standard G.984.1, G.984.2 and G.984.3 EPON (Ethernet PON) A new type of fiber-optic access network technology, it uses point-to-multipoint structure, passive optical fiber transmission, offers a variety of services on top of Ethernet.

Therefore, it combines the advantages of PON and Ethernet technology: low cost; high bandwidth; scalable, flexible and rapid service reorganization; compatibility with existing Ethernet; convenient management. Buy fiber optic supplies from GPON and EPON maufacturer, we also supply  CWDM module, DWDM module for GPON and EPON system.

What Is The Difference Between cat5e and cat6 Patch Cords

Cat 5e: Cat 5e (which stands for Category 5, enhanced) cable goes along the same lines as basic Cat 5, except that it fulfills higher standards of data transmission. While Cat 5 is common in existing cabling systems, Category 5e has almost entirely replaced it in new installations. Cat 5e can handle data transfer at 1000 Mbps, is suitable for Gigabit Ethernet, and experiences much lower levels of near-end crosstalk (NEXT) than Cat 5. Cat 6: Of the three cable categories we’re discussing, Category 6 is the most advanced and provides the best performance. Just like Cat 5 and Cat 5e, Category 6 cable is typically made up of four twisted pairs of copper wire, but its capabilities far exceed those of other cable types because of one particular structural difference: a longitudinal separator. This separator isolates each of the four pairs of twisted wire from the others, which reduces crosstalk, allows for faster data transfer, and gives Cat 6 cable twice the bandwidth of Cat 5! Cat 6 cable is ideal for supporting 10 Gigabit Ethernet, and is able to operate at up to 250 MHz. Since technology and standards are constantly evolving, Cat 6 is the wisest choice of cable when taking any possible future updates to your network into consideration. Not only is Category 6 cable future-safe, it is also backward-compatible with any previously-existing Cat 5 and Cat 5e cablingfound in older installations. The major difference between Cat5e and Cat6 is the quality of performance they provide. Cat5e is typically used for networks using 100 Mbit/s or a gigabit network, with performance of up to 100 MHz. For networks that can handle up to 250 MHz, you would want to make use of Cat6 cabling, as it offers more than twice the performance of a Cat5e. Although Cat6 may be able to handle greater data loads than Cat5e, it’s always best to use the proper patch cord to match the cabling in your building; it pays to find out what is already in use at your location before installing the network. Are Cat5e and Cat6 Compatible? You may be asking yourself ‘What if my building is set up to use Cat5e but all I have are Cat6 patch cords? Am I still able to use them?’ The answer to the question would be ‘Yes, you can!” As stated before, it’s preferential to match cable types; however, it is possible to mix and match Cat5e and Cat6 if necessary. If you’re unsure of the wiring of the building, you may also want to go with Cat6. To ensure maximum performance, you will want to use the best components possible all throughout the network.

How To Get Your Computer Optimization

Nobody likes a slow running computer, especially when you don’t have the funds to go out and get an entirely new unit, and it may be frustrating to watch your computer’s performance falter without the knowledge to do something to rectify it on your own. Without needing to really go too far outside of your comfort zone and spend a great deal of energy learning an entire new skill set in the process, but you may be surprised to find out just how simple it may be to make a few of these enhancements on your own. It may be for many reasons if your unit is running slowly, so completing the necessary homework ahead of time might be crucial and result in saving you quite a bit of time and money when it comes to finding a solution. If you find that it is a software problem, you can probably just download new drivers and fix the issue that way, but if it’s a hardware issue, there are a couple things you might do to increase your device’s efficiency. Letting you send and receive data at a faster pace, the simplest solution would be to just purchase a new router or modem with a higher signal output, but there are also some other choices for those who’re open to getting a little more up close and personal with their unit. You will find a more reliable, quicker connection with less lag and a more steady data transfer rate letting you stream video and work a lot faster than you were before by upgrading to any more powerful Cisco SFP modules. You can even go a step further than that by looking at other transceivers that surpass the performance ability established by SFP transceivers for those that are more aggressive when it comes to their unit’s performance. You may install any Cisco GLC T module in its place, for instance, with both components being of the same dimensions as well as being swappable hot form pluggable and even more dependable than their counterparts. Supplying a stream of information much more stable than you are probably experiencing presently, there modules may function at a rate of ten, one hundred, or one thousand Mbps speeds through up to one hundred meters of unshielded twisted-pair Ethernet cable. These are only some the choices available to you in order to boost your computer’s performance, but in order to get a better sense of what you can do, identify where your current issue lies, and then do the necessary research needed in order to discover if it is something you can take care of on your own; the results might surprise you.  

Effective Fiber Optic Communications Equipment-CWDM

The use of fiber optic cables for communication has opened up gates for communication multiplexing technologies that maximize the capabilities at minimum costs. Coarse wavelength division multiplexing, or CWDM, modulates different wavelength laser beams with multiple signals. In effect, this means maximized use of a single fiber optic to transmit and receive a large number of signals, minimizing costs for telecom companies. Companies simply use the right optical amplifiers, multiplexers and de-multiplexers to enhance capacity of the fiber optic using CWDM technology. Related technologies are dense wavelength division multiplexing (DWDM) and conventional WDM. Conventional WDM use the 3rd transmission window with a wavelength of 1550nm, accommodating up to 8 channels. DWDM is the same but with a higher density channel. Systems may use 40 channels, each at 100 GHz spacing or 80 channels spaced 50 GHz apart. A technology, the ultra dense WDM is capable of working at a spacing of only 12.5 GHz, allowing more channels. DWDM and WDM are expensive in contrast to CWDM. In CWDM technology, there is an increase in channel space. This translates to requirement of less sophisticated and less costly transceiver devices. Operating in the same window of 1550 nm and making use of OH-free silica fibers, maximum efficiencies are achieved in channels 31, 49, 51, 53, 55, 57, 59 and 61. The channels are spaced 20 nm apart. DWDM spaces them 0.4 nm apart. Less precision optics and lower cost, uncooled lasers with lower maintenance requirements can therefore be used in CWDM devices, operating in the region of 1470, 1490, 1510, 1530, 1550, 1570, 1590 and 1660nm. 18 different channels can be used with wavelengths up to 1270 nm. In addition to being cost effective, power consumption for laser devices used in CWDM technology is also far less. CWDM signals cannot be transmitted long range but are perfect for applications within a range of 60 km such as in a city and for cable television networks allowing upstream and downstream signals. A number of manufacturers offer all related CWDM multiplexers, demultiplexers and optical amplifiers. Networking solution providers are the right people to seek guidance for use of CWDM, DWDM or WDM technology. Networking solution providers carry out the entire installation and commissioning of the right, integrated devices for error-free high speed, high data transmissions over fiber optic lines. Cost and performance optimized CWDM solutions with built in expansion capabilities are available from reliable and trusted online network solution companies.

Using the GLC-SX-MM to Expand Communication Networks

With the rise of communication standards, global companies now come face-to-face with the fact that they have to upgrade their network systems. This way, they get to support data transform in any form. This is where periphery components like the cisco glc-sx-mm come in handy. The GLC-SX-MM is a hot-swappable tool that connects a Gigabit Ethernet interface, as well as the video machine to the main harbour with the multilevel. It is also commonly used between switches, Wireless LAN Controllers, and firewalls. It is a Short Form-Factor Pluggable that works well with a wide variety of products and services, and can be mixed and matched on a port-by-port basis. This makes it quite competent in either simple or extremely complex networking environments. On top of that, the GLC SX MM has high performance modules that sustain a data-rate of 1.25 Gbps. For multi-mode fibers, which is one of the most commonly installed types in corporate settings, it can transmit data up to 500mm. SFP transceiver usually come in different models. This allows the user to customize and configure the system in a way that it gets proper optical reach, either with multi-mode or single-mode optic fiber cables. The four categories of SFP modules are the SX, which is 850nm, the ZX, which is 1550 nm, the LX which is 1310 nm and theDWDM. They are typically made with copper cable interfaces, which allow a host device to connect via unshielded twisted-pair network cable. The CWDM can also be used through single optic cables, and they are 1310/1490 upstream and downstream. There are several known producers of SFPs and it is important that you get to know these brands, especially Cisco, if you’re planning to expand your network. That way, you get to acquire the right kind of gear that would complement your system. If you are looking to buy these things, you might as well stick to only one manufacturer, so that compatibility issues don’t arise. Despite the generalization of the IEEE standards that made parts more flexible and inter-changeable for various networking needs, there is still minimal guarantee that Avaya networking products would work with Netgear and Cisco gadgets. Now, since Cisco is one of the pioneering companies and established brands when it comes to network systems with 28 years of service, customers can rest assured that they will automatically work in any network set up and that in-house engineers will know how to configure them to stabilize the linkages. When buying SFP transceiver and supporting network tools, one can expect costly investments as these do not come cheap. However, with thorough research, it is possible for a company to get good prices for their purchases. It is essential, though, that they get expert advice first, before any transaction is made. That way, the desired outcomes are insured, and delays, as well as excess expenses will not be realized. The internet provides expansive information on network systems, as well as reliable retailers of networking accessories. Thus, you won’t have to break a sweat in looking for those exact pieces you require.

(D) Check the fiber optic connector is inserted into the device interface, Fiber patch cord type match with the device interface, device type and fiber match, whether the equipment transfer length matches the distance is intact. 4. Circuit Link light does not shine failure may be the following: (A) Check whether the cable disconnection (B) Check whether the connection type match: network cards and routers, and other devices use a crossover cable, switches, hubs, and other equipment using the straight line. (C) checking equipment transfer rate matches 5. Network packet loss the serious possible failure are as follows: (A) transceiver electrical port and network device interface, or both ends of the device interface duplex mode mismatch. (B) twisted-pair RJ-45 head detect (C) optical fiber connection jumper alignment device interface, pigtails and jumpers and coupler type matches. 6. Fiber Media Converter connect both ends can not communicate (A) Fibre reverse the TX and RX are connected to the optical fiber swap (B) RJ45 interface with external devices not connected properly (note that direct splicing) Optical fiber interface (ceramic ferrule) do not match, this failure is mainly reflected in the transceiver 100M with optical mutual control function, such as APC ferrule pigtails received PC ferrule on the transceiver can not communicate properly, but then non- the photoelectric interaction control transceiver has no effect. 7 when the pass off phenomenon (A) may be too large, for the optical path attenuation available optical power meter measuring the optical power of the receiving end, ,1-2dB in the vicinity of the scope of the receiving sensitivity range can be substantially determines the optical path failure (B) Switch connected to the fiber converter may be failure, the switch replaced PC, the two transceivers connect directly with the PC, both ends of the PING, Failure to appear when the pass off phenomenon basic judgment of switch failure (C) fiber converter may be failure at both ends of the converter then PC (not through a switch), both ends of the PING no problem, from one end to the other end of the transfer a large file (100M) above, observe it the speed, as the speed is very slow (less than 200M file transfer for more than 15 minutes) can be basic judgment transceiver failure. 8. Communication for some time after the crash, that can not communicate back to normal after re-starting This phenomenon is generally caused by a switch to switch on all data received CRC error detection and length check, check out the error packets will be discarded, the correct packet will be forwarded out. Some of the process error packets can not be detected in the CRC error detection and length checksum this packet forwarding process will not be sent out, it will not be discarded, they will accumulate in the dynamic cache (buffer), can never be sent accumulation in wait until the buffer is full, it will cause the switch to crash the phenomenon. Because transceiver restart or re-starting switch can make communication back to normal, so users often think that the problem of the transceiver. 9. Fiber media converter test methods in order to find out the cause of the malfunction (A) the proximal end of test: Both ends of the computer on the PING PING through that fiber media converters. Proximal test is not a failure of communication can be judged for fiber optic transceivers. (B) Remote Test: Both ends of the computer whether normal and fiber media converters transmit and receive power whether the allowed range of PING, PING not General must check the optical path connection. PING the General Clauses prove optical path connection. The problem is to determine fault in the switch. (C) Remote test to determine the point of failure: First one end of the switch, both ends of the PING if no fault can be judged by the fault of the other switches.
