SFP Function Description

- Jul 01, 2018-

Most optical SFP transceivers support SFF-8472 (Industrial Standard Multilateral Protocol), and under the SFF-8472 protocol, digital Diagnostic monitoring (DDM, digital Diagnostic Monitor) functionality must be supported, which enables end users to detect SFP parameters in real time , such as the basic 5 monitoring quantities: temperature (Temperature), transceiver supply voltage (VCC), laser bias current (Tx Bias), optical output power (Tx Power), input power (Rx Power).
