Optical filtering tolerant and spectrally efficient 200Gbps real-time transmission using flex-shaping algorithms

Real-time transmission of 46*200Gb/s channels within 37.5GHz grid over 16 cascaded WSSs is realized with less than 1.1dB penalty, thanks to software defined optics (SDO) enabled by configurable time-domain hybrid modulation (TDHM) and programmable optical domain equalization (ODE) algorithms, potentially suitable for field deployment in ROADM networks.
