Fiberstore 10Gbe SFP Direct Attach Cables

SFP (Small Form-factor Pluggable) products support various fiber optic and copper based transceivers and cable assemblies. The SFP was designed for Ethernet, Fibre Channel and InfiniBand applications up to 4Gb/s and based on the industry standard SFP Multi-Source Agreement (MSA). This interconnection style can be found in many different hardware verticals including, media converters, switches, servers and numerous data storage units.

QSFP stands for Quad Small Form Pluggable and was designed in parallel with the OM4 fiber optic standard to help support 40/100 Gbps transmission speeds. Offering 3 times the density of traditional SFP ports, the system is ideal for switches, routers, and host bus adapters (HBA's) where bandwidth is essential.

Qsfp to SFP+ cable is compose with QSFP moduels and Nx1 twinax cables with SFP+ transceivers. QSFP copper cable assemblies are a low cost option for short-reach applications; where as, active optical QSFP cable assemblies use state-of-the-art technology to provide cost effective high data throughput for longer distances. An example of this would be the Blazar 40 Gigabit Long Reach cable from Luxtera. It is a low power 40 Gbps Active Optical Cable assembly, containing four complete fiber optic transceivers per end, each operating at data rates from 1 to 10.3125 Gbps.

FiberStore QSFP+ to 4 SFP+ hybrid splitter cables make a great cost-effective interconnect solution to IT professionals by providing much needed space for data centers and cost cuts. These cables allow you to connect your QSFP+ and SFP+ Switches and Network cards without upgrading your entire data center or storage array. They can be used for QDR infiniBand, 40 Gigabit Ethernet and 10Gigabit applications. Each QSFP-SFP+ splitter cable features a single QSFP connector (SFF-8436) rated for 40-Gb/s on one end and (4) SFP+ connectors (SFF-8431), each rated for 10-Gb/s, on the other.

We also supply 10G SFP+ Direct Attach Cables which is twinax cable with SFP+ connector are designed to work with equipment with 10G SFP+ interface to provide high performance 10G Ethernet network, using an enhanced SFP+ connector sending 10G data over one paired transmitters and receivers, over a thin twinax  cable. FiberStore provides 10G SFP+ cables, including sfp 10gbe copper cable, active cable and 10G SFP+ AOC cable, in various lengths according to requirement of our customers.

CWDM Building Blocks from FiberStore

CWDM is a technique for transmitting signals by fiber, whih means division multiplexing light wavelengths. CWDM was standardized by the ITU-T on the recommendation of the G. 694.2 standard in 2002, based on a grid or wavelength separation of 20nm(or 2500 GHz) in range of 1270-1610 nm, and can carry up to 18 wavelengths via a singel pair fiber.

The main building blocks used in CWDM Network are Multiplexer and Demuliplexer.

CWDM MUX DEMUX- The passive CWDM MUX building block can aggregates wavelengths of light from several transmitter sources(TX) and transmits the combined linght into one fiber. Eash wavelength of light remains unchanged and transparent in the presence of neighboring wavelengths. Typically, CWDM MUX and DEMUXE modules are designed with a minumum of 4 channels to a maximum of 16 channels.

OADM- is illustrated in a protedted ring system. OADMs provide access to a singel or even more wavelengths of a wavelength-multiplexed system increasing the possibility of networking. Although this greatly improves the flexibility for CWDM, the insertion loss of these devices poses a challenge on the design of rings as CWDM uses no optical amplitication to overcome losses.

CWDM Transceiver- with embedded transmitter and receiver functions in a single packaged module. With different grades of performance,and have been integrated into WDM networks for point to point links, metro and core networks and storage area networks (SAN) applications such as data-center mirroring.

FiberStore CWDM transceivers can operate on 9/125um single-mode fiber to 40km or 80km by using special CWDM channels (1270nm to 1610nm, in steps of 20nm).

CWDM SFP transceiver- CWDM SFP Transceiver is a convenient and cost-effective solution for the adoption of Gigabit Ethernet and Fiber Channel(FC) in campus, data-center, and metropolitan-area access networks, with maximum optical budget 41dB. FiberStore CWDM SFP modules support data rates from 100 Mbps up to 4.25 Gbps. There are 18 center wavelengths available from 1270 nm to 1610 nm, with each step 20 nm. These wavelengths are compliant to the ITU G.694 CWDM standard

CWDM GBIC transceiver- CWDM GBIC transceivers are high performance, cost effective modules supporting data-rate of 1.25Gbps and 40km transmission distance with SMF. The transceivers meet the Gigabit Interface Converter (GBIC) specification Rev.5.5, for serial optical data communications such as Gigabit Ethernet 1000BASE-ZX and Fiber Channel 1x SM-LC-L FC-PI application. This module is designed for single-mode fiber and operates at a nominal wavelength of CWDM wavelength. There are eighteen center wavelengths available from 1270 nm to 1610 nm, with each step 20 nm.The transmitter section uses a multiple quantum well CWDM DFB laser and is a class 1 laser compliant according to International Safety Standard IEC-60825. The receiver section uses an integrated InGaAs detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC.

Fiberstore Flexible, Low-cost CWDM Mux Demux Device

Fiberstore introduces its new generation of coarse wavelength-division multiplexing (CWDM) passive devices boasting increased functions and improved performance to extend the reach of CWDM metropolitan networks

FiberStore CWDM Mux/Demux is a passive technology, it allows for any protocol to be transported over the link, as long as it is at a specific wavelength (i.e. T1 over fiber at 1570nm transported alongside 10Gbps Ethernet at 1590nm). This allows for long-term future proofing of the networking infrastructure because the multiplexers simply refract light at any network speed, regardless of the protocol being deployed.

FiberStore provides a complete portfolio of CWDM Mux Demux and Optical Add Drop Multiplexer (OADM) units to suit all applications such as:Gigabit & 10G Ethernet, SDH/SONET, ATM, ESCON, Fibre Channel, FTTx and CATV.
