Abstract:
1. An optical transceiver for converting and coupling an information-containing electrical signal with an optical fiber comprising: a housing including a base and a cover; an electrical interface subassembly in the housing with a plurality of XFI electrical interfaces for coupling with an external electrical cable or information system device and for transmitting and/or receiving an information-containing electrical signal having a data rate of at least 10 Gigabit per second on each interface, the electrical interface assembly comprising an SFI-5 signal processing circuit for converting between the information-containing electrical signal and a plurality of SFI-5 signals and a Serdes for converting between the plurality of SFI-5 signals and a plurality of electrical signals having a data rate of at least 10 Gigabit per second; a fiber optic connector in the housing and adapted for coupling with an external optical fiber for transmitting and/or receiving an optical communications signal having a data rate of at least 40 Gigabit per second; a transmitter subassembly in the housing for converting the plurality of electrical signals from the Serdes to an optical signal having a data rate of at least 40 Gigabit per second provided to the fiber optic connector; and a receiver subassembly in the housing for converting an optical signal having a data rate of at least 40 Gigabit per second from the fiber optic connector to corresponding electrical signals provided to the Serdes.
