Apparatus and method for transmitting 10 Gigabit Ethernet LAN signals over a transport system
A computer system and method for transmitting 10 Gigabit Ethernet (10GE) LAN signals over transport systems. Standard 10GE LAN signals are generated in any client IEEE 802.3 10GE LAN compliant interface. A transceiver receives the client 10GE LAN signal in the LAN format. The client 10GE LAN signals are not converted to a SONET transmission format at any time before reaching the transceiver. The transceiver then converts the client 10GE LAN signal to an internal electrical 10GE LAN signal before re-clocking the internal electrical LAN signal. The re-clocked internal electrical 10GE LAN signal is then re-modulated into a second 10GE LAN signal. The second 10GE LAN signal is then transmitted to a transport system.
