A DEVICE FOR CROSSTALK CANCELLATION IN OPTICAL TRANSCEIVERS

摘要

A device useful for cancellation of crosstalk in an optical transceiver, integrating transmission of an output signal and reception of an input signal comprising:a tunable filter for cancelling the crosstalk component from the transmitter to the receiver; a delay element for closing the gap between the input signal and cancelled crosstalk component; and an adaptation circuit for adjusting to the changing characteristics of the device, such as the signal to noise and distortion ratio and the relative amounts of electrical and optical crosstalk, such that the crosstalk component from the transmitter to the receiver is more fully cancelled.
