Digital Upstream Crosstalk Cancellation for Future (T)WDM-PON Systems

We experimentally demonstrate a multiple-input multiple-output (MIMO) scheme for compensating upstream crosstalk in (T)WDM passive optical network (PON) systems in the electrical domain. The scheme relaxes the optical receiver filter isolation requirements by up to 9   dB, and thus enables ...
