  • Differential optical signal receiver
    Patent number: 6175438
    Abstract: A differential optical signal receiver includes an interference-rejecting circuit to provide enhanced interference signal rejection. The differential optical signal receiver includes a differential optical signal detector for detecting a received differential optical signal and converting it to a differential electrical signal. An interference-rejecting differential electrical circuit, including a common source load, processes the differential electrical signal so as to reject any electrical interference signal other than said differential electrical signal.
