Method, apparatus and systems for a wavelength division multiplexing system operating at 0-Band. The system includes a transmitter for wavelength division multiplexing digital 0-band optical channels into a multiplexed optical signal, amplifying and transmitting the multiplexed optical signal, a fiber transmission span using constant intensity modulation and semiconductor optical amplification, and a receiver for receiving and amplifying the transmitted multiplexed optical signal and restoring the individual digital 0-band optical signals. In an embodiment, the transmission span is a single mode fiber transmission span and in another embodiment includes an optical amplifier module coupled into the fiber transmission span. In another embodiment, the transmission span includes a length of 0- band dispersion compensating fiber to reduce four-wave mixing. In another embodiment the system uses wavelength division multiplexing in combination with polarization interleaving. In another embo
