Finisar announces volume production of CWDM family


Finisar has increased production of its coarse wave division multiplexing modules. The company claims to be the first to deliver a full line of optical modules based on CWDM. The range includes every major optical component necessary to support a metro access optical data network, including transceivers (available in eight wavelengths between 1470 and 1610nm), optical add-drop multiplexers (OADMs) and multiplexers/demuxes.

Supporting products include the FTR 1621xx and the FTR 1619xx GBIC transceivers, FWS-OADM passive optical add-drop multiplexers and the FWS-MUX/DEMUX. The FTR1621xx is a multi-rate GBIC transceiver which operates at data rates from 125Mbit/s to 2.7Gbit/s with 28dB receiver sensitivity.

The 1619xx operates at 1Gbit/s Fibre Channel and 1.25Gbit/s GbitE data rates with 30dB receiver sensitivity. Digital diagnostic functions provide calibrated real-time measurements of the laser bias current, the transmitted and received optical power, and internal transceiver temperature.

  • Finisar has also announced that it plans to introduce a DWDM transceiver, ahead of Supercomm 2002, that will enable DWDM transmissions over a CWDM network. This development could see eight narrow channels fitted into each of the eight broad channels of the CWDM system, giving 64 DWDM channels on a CWDM architecture.

Jim Aldridge, senior marketing manager told Lightwave Europe, "The strategy of WDM is that the network can carry multiple wavelengths with, for example, SONET on one wavelength and IP on another."

  • Finisar named Jan Meise as its new international sales and marketing manager for Finisar Optics. He will develop the sales channels for optical subsystems in Europe and Asia as well as customer partnerships, and aim to increase the market for broad optical transceivers. Educated at the Technical University of Braunschweig, Germany, Meise moves to his new post from QuickLogic.
