Abstract:
1. An electro-optical transceiver module having a plurality of optical transmit lanes and a plurality of parallel optical receive lanes, the module comprising: signal detection circuitry operably coupled to the plurality of optical receive lanes and being operable to detect a loss of optical power on a specific optical receive lane of the plurality of optical receive lanes; and control circuitry operably coupled to the signal detection circuitry, the control circuitry being configured to generate a power loss indicator in response to the loss of optical power on the specific optical receive line, the power loss indicator indicating that the loss of optical power occurred on the specific optical receive lane, the control circuitry being operably coupled to the plurality of optical transmit lanes such that a power level of a signal provided to a specific optical transmit lane corresponding to the specific optical receive lane and to a remote transceiver module is reduced from a first optical power level to a second optical power level.
