Abstract

See full text

A method and apparatus for processing a communication signal in an optical network. A network node typically includes a transmit train for generating transmissions and a receive train for receiving transmissions from another network node. The network node may be, for example, an OLT or an ONU. In a receiver implementing the described solution, a photodiode is employed to convert received optical signals into electrical signals that are then provided to a TIA or other device for producing a differential output having an inverted output and a non-inverted output. One of the outputs is delayed one bit and attenuated, then combined with the other output to produce an equalized signal for further processing by the receive train. The solution may be analogously applied on the transmit side for introducing pre-distortion, either in addition to or in lieu of in the receiver.
