ABSTRACT:
A single chip integrated circuit for use in an optical transceiver for converting and coupling an information containing electrical signal with an optical fiber having an XFI interface for coupling with an external electrical cable or information system device, and an XAUI interface for coupling with a laser transmitter subassembly including first, second, third and fourth lasers operating at different wavelengths and modulated by the respective four lane XAUI signals. The circuit includes an encoder for encoding the incoming XFI signal into four signals in the XAIU format, and a decoder coupled to the XAUI interface for receiving a four lane XAUI signal and converting it into a serial XFI signal coupled to the XFI interface.
