Abstract:
A mode division multiplexing passive optical network (PON) in which channel estimation/inversion is performed in the optical domain. The PON comprises a plurality of input channels; a multiplexer having a plurality of input ports connected to a respective one of the input channels; an optical fibre having an uplink end connected to an output port of the multiplexer, whereby the multiplexer outputs a mode multiplexed signal corresponding to the optical signals from the plurality of input channels. The PON includes an optical equalizer arranged to transfer power between optical signals having different modes to compensate for crosstalk between the different modes. In this system, compensation for crosstalk occurs in the optical domain, e.g. by using the optical equalizer to adapt the optical signals where necessary.

Claim (Index 8):
A mode division multiplexing passive optical network according to  Claim 1 , wherein the optical equalizer is connected between the plurality of output ports of the demultiplexer and the plurality of output channels to perform downlink crosstalk compensation.
