Ulwazi nokuphathwa kwe-SFP Module EEPROM
Amamojula e-SFP asebenzisa i-2-wire serial communication protocol njengoba kuchazwe ku-SFP -8472. Imininingwane ye-serial ID yamamojula e-SFP kanye nemingcele ye-Digital Diagnostic Monitor ingafinyelelwa nge-I.2C interface ekhelini A0h kanye A2h. Inkumbulo ifakwe kumephu kuThebula 1. Ulwazi lwe-ID enemininingwane (A0h) lufakwe kuThebula 2., kanye timininingwane ye-DDM ekhelini elithi A2h. Ukuze uthole imininingwane eyengeziwe yemephu yememori nezincazelo ze-byte, sicela ubheke i-SFF-8472, “I-Digital Diagnostic Monitoring Interface yama-Optical Transceivers”. Amapharamitha e-DDM akalwe ngaphakathi.
