It also adds new options to the previously defined two-wire interface ID memory m

44、ap that accommodate new transceiver types that were not considered in the SFP MSA or GBIC documents. The interface is an extension of the two-wire interface ID interface defined in the GBIC specification as well as the SFP MSA. Both specifications define a 256 byte memory map in EEPROM which is acce

45、ssible over a 2 wire serial interface at the 8 bit address 1010000X (A0h). The digital diagnostic monitoring interface makes use of the 8 bit address 1010001X (A2h), so the originally defined two-wire interface ID memory map remains unchanged. The interface is backward compatible with both the GBIC
