Finisar's line of coarse wavelength division multiplexing (CWDM) modules is now in volume production. Finisar is the first company to deliver a full line of optical modules based on CWDM. Finisar's CWDM product family includes every major optical component needed to support a metro access optical data network, including transceivers (available in eight specific wavelengths between 1470 and 1610nm), optical add/drop multiplexers (OADMs) and multiplexers/ demultiplexers.
These products include the FTR-1621-xx and FTR-1619-xx GBIC transceivers, FWS-OADM passive optical add/drop multiplexers and FWS-MUX/DEMUX multiplexers/demultiplexers.
The FTR-1621-xx is a multirate GBIC transceiver that operates at datarates from 125Mbit/s to 2.7Gbit/s (OC-48 datarates) with 28dB receiver sensitivity.
The FTR-1619-xx operates at 1.0625Gbit/s Fibre Channel and 1.25Gbit/s gigabit Ethernet datarates with 30dB receiver sensitivity.
As in all other Finisar optical GBIC modules, "smart" digital diagnostic functions are provided.
These digital diagnostic functions provide calibrated real time measurements of the laser bias current, the transmitted optical power, the received optical power, and the internal transceiver temperature.
The FTR-1621-xx and FTR-1619-xx are available in eight wavelengths: 1470, 1490,1510, 1530, 1550, 1570, 1590 and 1610nm.
The FWS-OADM adds/drops a single CWDM wavelength from network traffic and passes the other wavelengths.
The FWS-MUX/DEMUX multiplexes and demultiplexes four or eight CWDM wavelength channels from a pair of fibres.
Add/dropped and multiplexed/demultiplexed wavelengths are interfaced to any of Finisar's CWDM transceivers installed in an existing GBIC slot in network equipment.
The FWS-OADM and FWS-MUX/DEMUX are available as plug-ins with a 1RU chassis for system applications or as a module with fibre optic pigtails that enable OEMs to design circuit boards with CWDM capability.
Finisar's CWDM GBICs work with Finisar OADMs and mux/demuxes to create sophisticated metropolitan area networks that address the key issues for network providers: transparency, scalability and cost-effectiveness.
