Description: The options implemented in the SFP transceiver unknown -- Unknown rateSelect -- RATE_SELECT is implemented. If this bit is not set, no control of pin is required. If this bit is set, then active control if the rate select pin is required. In Both cases, compliance with mlutiple rate standards should be determined by the following objects sfpTransceiverComplianceCodes sfpFibreChannelTransmissionSpeed txDisable -- TX_DISABLE is impelmented and disables the serial output txFault -- TX_FAULT is implemented. losNormal -- loss of signal implemented los high indicates the received optical power is below the worst case receiver sensitivity (as defined by the standard in use. los low indicates normal operation losInverted -- loss of signal implemented los low indicates the received optical power is below the worst case receiver sensitivity (as defined by the standard in use. los high indicates normal operation
