Fiber optic enterprise network using wdm, dwdm, infiniband, cwdm & roadm technology: Lightwave

DWDM & ROADM

DWDM and reconfigurable optical add/drop multiplexer (ROADM) systems are the linchpins of next generation networks. Today’s DWDM systems feature high channel count and longer reach. Meanwhile, colorless, directionless, contentionless, and gridless ROADM features are either available now or on the drawing board.

Watch for silicon photonics on the line side

Thu Oct 23 15:04:00 CDT 2014
Most of the hullabaloo around silicon photonics has centered on its application to data center networks. But presentations and announcements at last month’s ECOC in Cannes, France, indicate the technology will play on the line side as well. For example, Acacia Communications used the show to further publicize its use of sili...
