Demonstration of single channel 160-Gb/s OTDM 100-km transmission system

A 16 × 10-Gb/s optical time-division-multiplexing (OTDM) 100-km transmission system with home-made multiplexer is demonstrated experimentally. A demultiplexer based on two cascaded electro-absorption modulator (EAM) and a clock recovery unit form a feedback loop. Error-free demultiplexing from 160-Gb/s to 10-Gb/s after over 100-km transmission is achieved. The power penalty is about 3.5 dB with the bit error rate of 10−9.
