200G IM/DD Time-and-Polarization-Division-Multiplexed PON with >29dB Power Budget Using Boosted EML and APDs

We experimentally show feasibility of downstream 200 Gbit/s IM/DD TPDM PON system with >4 dB margin to 29 dB optical power budget based on two 100 Gbit/s polarization channels in a single wavelength window. The system uses SBS suppression to mitigate nonlinear fiber loss and duoternary modulation to overcome bandwidth limitation.
