Abstract
A link pulse translation circuit includes transmit portion circuitry that receives a first link pulse signal, having a first level, from a physical layer device. The transmit portion circuitry translates the first link pulse signal into a second link pulse signal that has a second level suitable for driving transmit portion circuitry of an optical transceiver. Receive portion circuitry receives a signal detect signal from receive portion circuitry of an optical transceiver, the receive portion circuitry of the optical transceiver asserting the signal detect signal in response to an optical pulse signal being provided on an optical medium to which the receive portion circuitry of the optical transceiver is coupled. The receive portion circuitry provides a third link pulse signal, having the first level and corresponding to the optical pulse signal, to the physical layer device.
