MRV begins manufacture of CWDM transceivers

3/30/00 MRV Communications Inc. (Chatsworth, CA) has begun manufacturing its coarse wavelength-division multiplexing (CWDM) transceivers for metropolitan and regional networks. This is the first 10-Gbit/sec transceiver module in the industry using CWDM technology, says MRV, with distance support up to 50 km.

3/30/00 MRV Communications Inc. (Chatsworth, CA) has begun manufacturing its coarse wavelength-division multiplexing (CWDM) transceivers for metropolitan and regional networks. This is the first 10-Gbit/sec transceiver module in the industry using CWDM technology, says MRV, with distance support up to 50 km.

The optical 4xtransceiver line is offered at speeds of 4xOC12, 4xGigabit Ethernet, or 4xOC48 and 1xOC-192 with distances up to 80 km, 65 km, and 50 km, respectively. The transceivers transmit four channels using four wavelengths in the 1.5-micrometer low-loss fiber window.

The transceivers will be used in high-speed connections of ATM switches and IP routers. In addition, they can solve fiber exhaust problems by concentrating traffic using WDM technology. Where fiber availability is limited, a four times increase can provide the necessary bandwidth.

The CWDM transceiver modules will be available beginning in the second quarter of 2000.
