Abstract
We demonstrate a capacity upgrade to a 40-Gb/s channel rate with reconfigurable optical add-drop multiplexing (ROADM) operation from a 32×10-Gb/s-based unrepeated WDM link. The 16×40-Gb/s channels were added at the ROADM node without traffic interruption in the expressed channels. The worst channel of the 40-Gb/s rate shows 1.1 dB of Q-value margin to the forward error correction (FEC) limit. The expressed 10-Gb/s channels also satisfy the transmission limit of the bit error ratio (BER) 10-15 without FEC operation. © 2006 Society of Photo-Optical Instrumentation Engineers.
