100km Field Trial of 1.24 Tbit/s, Spectral Efficient Asynchronous 5 WDM×25 DPSK-OCDMA Using One Set of 50×50 Ports Large Scale En/Decoder

Field trial of Terabit payload capacity (1.24 Tb/s), spectral efficient (SE>0.41 bit/s/Hz) asynchronous WDM/DPSK-OCDMA system is demonstrated for the first time with a set of large scale (50×50 ports, 500 Gchip/s) multi-port en/decoder and FEC.
