Patent ID: 8041226

Claim:
An optical transceiver, comprising: a transmitter including a semiconductor laser diode for emitting a transmitted optical signal to a first optical fiber and a first equalizer unit for outputting to said laser diode a first electrical signal equalized from a transmitted electrical signal input to said transmitter; and a receiver including a photodiode for converting a received optical signal provided from a second optical fiber to a second electrical signal, and a second equalizer unit for outputting a received electrical signal equalized from said second electrical signal output from said photodiode, wherein said first equalizer unit in said transmitter has a same configuration with said second equalizer unit in said receiver, and includes a plurality of delay blocks and a plurality of multiplier blocks each coupling with a corresponding delay block and multiplying an output from said corresponding delay block by a tap coefficient specific to each multiplier block, wherein said tap coefficients of said first equalizer unit are set based on tap coefficients of said second equalizer unit, wherein said first equalizer unit compensates frequency distortion contained in said first electrical signal, frequency distortion contained in said second electrical signal, and frequency distortion of said laser diode and said photodiode, and wherein said second equalizer unit compensates dispersion of said second optical fiber.
