International Classification:

H04B 10/24

US Classification:

398135

Abstract:

An optical transceiver converting and coupling an information-containing electrical signal with an optical fiber including a housing conforming to the industry standard XENPAK™ form factor including an electrical connector for coupling with an external electrical cable or information system device and for transmitting and/or receiving an information-containing electrical communications signal, and a fiber optic connector adapted for coupling with an external optical fiber for transmitting and/or receiving an optical communications signal.
