Apparatus and method for transmitting LAN signals over a transport system

摘要

A computer system and method for transmitting LAN signals over transport systems. LAN signals are generated in any client LAN compliant interface. A transceiver receives the client LAN signal in the LAN format. The client LAN signals are not converted to a SONET transmission format at any time before reaching the transceiver. The transceiver then converts the client LAN signal to an internal electrical LAN signal before re-clocking the internal electrical LAN signal. The re-clocked internal electrical LAN signal is then re-modulated into a second LAN signal. The second LAN signal is then transmitted to a transport system.

1. A transceiver for use with at least 10 Gigabit Ethernet (10GE) optical signals, the transceiver comprising:
a first line optics module configured to receive a first optical signal propagating in a first direction, and to convert the first optical signal into a first electrical signal; a first demultiplexer configured to demultiplex the first electrical signal to generate a first demultiplexed electrical signal; a second line optics module configured to receive a second optical signal propagating in a second direction and to convert the second optical signal into a second electrical signal; a second demultiplexer configured to demultiplex the second electrical signal to generate a second demultiplexed electrical signal; a first forward error corrector configured to add redundant information to first data included in the first demultiplexed electrical signal to allow for recovery of potentially damaged bits in the first data; a second forward error corrector configured to add redundant information to second data included in the second demultiplexed electrical signal to allow for recovery of potentially damaged bits in the second data, wherein the first forward error corrector is further configured to recover corrupted data from the second demultiplexed electrical signal before the redundant information is added to the second data included in the second demultiplexed electrical signal; a first multiplexer configured to multiplex the first demultiplexed electrical signal to generate a first multiplexed electrical signal; and a second multiplexer configured to multiplex the second demultiplexed electrical signal to generate a second multiplexed electrical signal, wherein the first line optics module is configured to convert the second multiplexed electrical signal into a third optical signal, and wherein the second line optics module is configured to convert the first multiplexed electrical signal into a fourth optical signal.
