System, apparatus and method for supporting multiple-interfaces for optical fiber communication

摘要

A multiple-interface apparatus, and networking device including: a plurality of system side lanes configured to connect to an electrical signal source; and a plurality of line side lanes, wherein the number of the plurality of line side lanes matches the number of the plurality of system side lanes, including: a first set of line side lanes configured to connect to a first optical transceiver module; and a second set of line side lanes configured to connect to a second optical transceiver module; a mode selector module configured to transmit the electrical signal to the first optical transceiver module on the first set of line side lanes or the second optical transceiver module on the second set of line side lanes; and an adaptation module to adapt the electrical signal for at least one of the first or second set of line side lanes.

1. A multiple-interface apparatus comprising:
a system side port comprising a plurality of system side lanes configured to connect to an electrical signal source and receive an electrical signal; and a line side port comprising a plurality of line side lanes, wherein the number of the plurality of line side lanes matches the number of the plurality of system side lanes, comprising:
a first set of line side lanes configured to connect to a first optical transceiver module; anda second set of line side lanes configured to connect to a second optical transceiver module; a mode selector module that receives the electrical signal from the system side port and is configured to select a mode of operation from either a pass-through mode or an adaptation mode based on data being transmitted by the electrical signal such that the electrical signal is sent to the first optical transceiver module on the first set of line side lanes or the second optical transceiver module on the second set of line side lanes based on the selected mode; and an adaptation module, which, when adaptation mode is selected, receives the electrical signal from the mode selector module and is configured to adapt the electrical signal, to form an adapted electrical signal, for at least one of the first set of line side lanes or the second set of line side lanes, and supply the adapted electrical signal to the first or second optical transceiver module via the line side port.
