Multichannel-Mixed OOK and DPSK Format Transmission Performance between Midspan TDCM and OPC System

We demonstrated the transmission performance between the midspan of tunable-dispersion-compensator-module-(TDCM) and optical-phase-conjugate-(OPC) with specialty using multichannel-mixed OOK and DPSK format. The OPC scheme has the advantage over the penalties performance compared to TDCM scheme.
