Say the part name and you have read the datasheet header: SFP-10G-DW42-80KM-TFO — 10G, SFP package, DW42 designation, 80km reach — with TenFourOptics building the Cisco-coded version of that exact combination. The EEPROM is programmed so a Cisco host identifies the module at insertion, the 80km rating puts far-flung sites within range of a standard SFP port, and DDM/DOM data stays available for as long as the link runs. Nothing else about the port or its neighbors needs attention during the exchange.
