Abstract :
A low-complexity polarization multiplexed Passive Optical Network (PON) architecture based on Multiple Input Multiple Output (MIMO) polarization beamforming is experimentally demonstrated, achieving twice the throughput for both downstream and upstream transmissions. In addition, a novel dynamic power allocation scheme further improves the loss budget by up to ~1.8 dB in the downstream direction.
