Abstract :
We propose an inexpensive multilevel transmission system that uses several laser diodes (LDs) of different wavelengths and receives each stream as a block. To compensate for the skew induced by group velocity dispersion (GVD), we propose a dynamic skew compensation method and fabricate a prototype LSI. Experiments show that 5 Gbps transmission can be achieved in a network (NW) with a loss budget only 0.73 dB lower than that of a 2.5 Gbps binary transmission.
