1000Base-SX Standard and 1000Base-SX SFP Module

An Ethernet standard that transmits at 1 Gbps. Used mostly to connect high-end workstations and servers as well as for network backbones, Gigabit Ethernet transmits full duplex from point to point using switches and half duplex in a shared environment (CSMA/CD) using a hub. The first IEEE Gigabit Ethernet standard (802.3z) was defined in 1997 for use over multimode optical fiber and two years later for copper cables 1000BASE-SX is one of the IEEE802.3z standard made for the laser transceiver witch work on short wavelength multimode fiber (850mm). When use 62.5pm multimode fiber, link distances can be up to 260m; when use 50pm multimode fiber, connection distance up to 550m. 1000Base SX SFP is the small form hot swappable fiber optic transceiver, which work with multimode fiber for linking. When used with 62.5 MMF its max-working span is around 220 meters, when used with 50 MMF its max-working span is around 550 meters. Typical 1000Base SX transceivers like Cisco GLC SX MM and SFP GE S. the latter is with DOM support and extended working temperature. The maximum distance between nodes is based on the type of transceiver and cable used as outlined below. 1000Base-SX (802.3z) 62.5 multimode 160 220 62.5 multimode 200 275 50 multimode 400 500 50 multimode 500 550 1000Base SX SFP tranceiver are used in Gigabit Ethernet and they are fully compatible with 1000Base-SX standards defined by IEEE. Fiberstore offer the 1000Base SX SFP transceiver modules, our products are fully compatible with IEEE 802.3z for Gigabit Ethernet and our optical transceivers are fully compatible to use with the equipment from other suppliers.

Cisco GBIC Product Line Application

The word GBIC is an IT industry term which stands for Gigabit Interface Converter. A GBIC is a variety of Optical Transceiver, which is designed to convert serial electric signals into serial optical signals. GBIC modules are typically inserted into a network switch in order to connect a Fiber Optic system with an Ethernet system. The most common applications where GBIC modules are used include Fibre Channel and Gigabit Ethernet. The GBIC is fully hot swappable, which adds to its flexibility and ease of installation. It has become a standard form factor for optical transceivers, and can support a variety of physical media, from legacy copper to long wave single mode fiber up to lengths of hundreds of kilometers Cisco GBIC modules and 3rd party equivalent, MSA (Multi Source Agreement) compliant modules can be interchanged on a wide variety of Cisco products and can be intermixed in combinations of 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX, 1000BASE-CWDM, or 1000BASE-DWDM interfaces on a port-by-port basis. The WS-G5483 is Cisco’s 1000BASE-T GBIC product, which connects a GBIC port to Category 5 wiring using a standard RJ-45 interface. The maximum Category 5 wiring distance is 328 feet (100 meters). The WS-G5484 is Cisco’s 1000BASE-SX GBIC product, which operates on legacy multimode fiber (MMF) optic link spans up to 1815 feet (550 m) and on laser-optimized multimode fiber (OM3) optic link spans up to 3281 feet (1 km). The Cisco WS-G5486 is Cisco’s 1000BASE-LX/LH GBIC product, which allows for reaches up to 6.2 miles (10 km) over single-mode fiber (SMF) and up to 550 meters over multimode fiber (MMF). The Cisco WS-G5487 is Cisco’s 1000BASE-ZX GBIC product, which operates on ordinary single-mode fiber optic link spans up to 43.4 miles (70 km) long. Link spans of up to 62 miles (100 km) are possible using premium single-mode fiber or dispersion shifted single-mode fiber. The GBIC provides an optical link budget of 21 dB – the precise link span length will depend on multiple factors such as fiber quality, number of splices, and connectors

The bandwidth and window of Fiber optic cable

Optical fiber in theory, its bandwidth is infinitely high, the transmission capacity is infinitely large, the transmission distance is infinity. The lighter weight is almost perfectly signal transmission medium can simultaneously transmit N-way telephone, an N-channel TV signal …… However, current applications, fiber optic cable is farther with the theoretical difference. Fragile physical properties of silica aside aside, its transmission capacity is only open several windows. In May 2002, ITU-T tissue optical band of the optical fiber communication system is divided into O, E, S, C, L, U6 a band. Known as the first window, single-mode optical fiber O with 2 window multimode fiber 850nm C with said window 3 L with 4 windows, E with 5 window. Multimode fiber and single-mode fiber communication band summary can be listed in the following table
Frequency band Window Wavelength range (nm) Frequency range (THz)
1 850(770-910)
Original band 2 1260-1360 237.9-220.4
Extended band 5 1360-1460 220.4-205.3
Short wavelength band 1460-1530 205.3-195.9
Conventional band 3 1530-1565 195.9-191.6
Longer wavelength band 4 1565-1625 191.6-184.5
Ultralength wavelength band 1625-1675 184.5-179.0
Due to the lower prices of the LED light source, 850nm, 1300nm wavelength with multi-mode fiber optic cable to set up a small network of choice for laser light source 1310nm wavelength 1550 nm single-mode fiber optic cable can constitute the basis of a large network, if the single-mode fiber optic cable available window morewords, wavelength division multiplexing (MDM) will be a core fiber multi-wavelength optical signals transmit at the same time to achieve ultra-high speed transmission effect, so you can maximize the potential of the single-mode fiber optic cable. 2 core telephone line telephony and network use at the same time, by ADSL “cat” because voice and data use different frequency, wavelength division multiplexing (MDM) technology principle similar to ADSL technology, this technology is generally used in the bandwidth requirements of a higher position backbone. Intelligent building applications, fiber optic cable is often close to support multi-mode-based, such as multi-mode fiber optic cable with the emission wavelength of 850nm or 1300nm LED light source, or 850nm VCSEL laser wavelength. Single-mode used in long distance system buildings, single-mode fiber optic cable with emission wavelength 1310nm or 1550nm FP or DFB laser, means that most of the fiber optic cable is only open a window. The fiber optic cable can transfer window open, open a few, which are subject to dispersion, loss, DMD, PMD and other factors, but also with light sources and other network equipment. From a long-term perspective, the more support window cable in practicality, compatibility, scalability is higher.
