Transmitter based on DFB laser array. MZ-modulator produces OFDM signal. 4-QAM OFDM signal. N=122 carriers with 528MHz bandwidth per band. 1xN power spilitter with an SOA switch in each arm. Acts as a high-speed optical switch to route the signal to the input ports of NxN AWG. SOA switches is also used as amplifiers to compensate for the loss of the splitter. The SOAs are activated according to the Latin routing characteristics of NxN AWG.
