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.

Overcoming the alphabet soup of form factors with 100G QSFP28

Wed Aug 06 16:00:00 CDT 2014
When the IEEE finished the first 100G standard for Ethernet networks, the transceiver industry launched an alphabet soup of form factors. The CFP emerged first, "C" for 100, and FP for "Form factor, Pluggable." Like the early versions of 10G transceivers, the CFP was huge. When compared to the mo...
