Finisar Corp has a new line of coarse wave division multiplexing (CWDM) optical transceivers, the FWDM-1621 and FWDM-1619.
Finisar Corp has a new line of coarse wave division multiplexing (CWDM) optical transceivers, the FWDM-1621 and FWDM-1619 Using Finisar's advanced APD technology, these transceivers are designed expressly for metropolitan area networks requiring high-speed, optical communications at datarates from 622Mbit/s to 2.7Gbit/s and link budgets of up to 30dB

The Longwave fibre channel SFP+ 1310nm transceivers support 1.4km and 10km transmission over single-mode fibre.
Both products are fully compliant with the small form factor pluggable (SFP) multisource agreement.
The FWDM-1621 and FWDM-1619 transceivers provide a cost-effective solution for metro access topologies where gigabit-rate signals need to be transported between locations separated by metropolitan distances.
Finisar's CWDM SFP transceivers work with its OADMs and mux/demuxs to create sophisticated metropolitan area networks that address the key issues for network providers: transparency, scalability and cost-effectiveness.
"Applying our 2.7Gbit/s APD technology to an SFP transceiver represents a milestone in optical transceiver design", said Andreas Weber, Director of Product Development for Gigabit Transceiver Products at Finisar.
"This step is just the beginning for us in developing the next generation of fibre optic transceivers", he added.
The FWDM-1621 is a multirate transceiver that operates at datarates from 622Mbit/s to 2.7Gbit/s with -28dBm receiver sensitivity.
The FWDM-1619 operates from 622Mbit/s to 1.0625Gbit/s Fibre Channel and 1.25Gbit/s Gigabit Ethernet datarates with -30dBm receiver sensitivity.
The FWDM-1621 and FWDM-1619 use CWDM ITU-grid DFB lasers in eight wavelengths: 1470, 1490, 1510, 1530, 1550, 1570, 1590 and 1610nm.
As in all other Finisar optical SFP modules, "smart" digital diagnostic functions are supported.
These digital diagnostic functions provide calibrated real time measurements of the laser bias current, transmitted optical power, received optical power, internal transceiver temperature and the supply voltage.
They allow communications companies to implement reliable performance monitoring of the optical link in a very accurate and cost-effective way.
Sample availability is September 2002.
Full production is expected December 2002.
Finisar will be showing the FWDM-1621 and FWDM-1619 optical transceivers at ECOC in Copenhagen.
