CROSSTALK SUPPRESSION METHOD AND APPARATUS

摘要

Embodiments of the present invention provide a crosstalk suppression method and apparatus. By obtaining a first electrical signal indicating a data bit stream of a first optical signal output by a laser diode (LD) in an optical transceiver module and a transmission parameter of a photodiode (PD), adjusting the first electrical signal based on the transmission parameter of the PD to obtain a third electrical signal indicating an electrical signal transformed by the PD from the first optical signal transmitted by the LD, and subtracting the third electrical signal from a second electrical signal output by the PD in the optical transceiver module, an electrical signal generated by the optical signal transmitted by the LD and reflected or refracted to the PD is removed from the electrical signal output by the PD, thereby suppressing crosstalk and improving the sensitivity of the optical transceiver module.

1. A crosstalk suppression method, comprising:
obtaining a first electrical signal that indicates a data bit stream of a first optical signal output by a laser diode (LD) in an optical transceiver module; obtaining a second electrical signal output by a photodiode (PD) in the optical transceiver module; adjusting the first electrical signal based on a pre-obtained transmission parameter of the PD to obtain a third electrical signal that indicates, as part of the second electrical signal, an electrical signal transformed by the PD from the first optical signal transmitted by the LD; and subtracting the third electrical signal from the second electrical signal to obtain an electrical signal transformed by the PD from an optical signal output from an external signal source.
