[pdf] DDM data can be accessed through switch CLI commands, SNMP, or dedicated DDM readers. The data is typically displayed in a table format showing current values, high/low alarm. Every pluggable optical transceiver (SFP, SFP+, QSFP, QSFP28, etc. ) ships with a small EEPROM that stores two kinds of information: a fixed Serial-ID block (vendor, part number, serial number, capabilities) and—when provided—a diagnostics area (real-time temperature, voltage, TX/RX power, etc. It allows real-time monitoring of important operational parameters, helping maintain network performance, detect faults early, and simplify troubleshooting. Glancing at the SFP specification, the Acronyms — DDM or DOM may catch your sight.
