Abstract: A transceiver includes a transmitter and a receiver. The transmitter includes a precoder stage, an encoder stage and a first converter stage. The precoder stage receives an input binary signal and a previously processed binary signal. The encoder stage is electrically coupled to the precoder stage and the first converter stage and includes a feed forward equalizer (FFE). The first converter stage generates a modulated signal. The receiver includes a second converter stage, an amplifier stage, a first equalizer stage and a second equalizer stage. The second converter stage receives the modulated signal. The first equalizer stage is electrically coupled to the amplifier stage. The second equalizer stage is electrically coupled to the first equalizer stage. The second equalizer stage includes a decision feedback equalizer (DFE) that converts the modulated signal into an output binary signal.

Abstract: An optical to electrical converter is to receive an incoming optical data communications signal. A binary to ternary encoder has an input coupled to an output of the converter. A ternary to binary decoder has first and second limiting amplifiers, each having a pair of complementary inputs. One of the inputs of each pair is coupled to a first adjustable threshold circuit and the other is coupled to an output of the encoder. A logical summing circuit has a pair of inputs coupled to outputs of the first and second limiting amplifiers, respectively. Other embodiments are also described and claimed.
