Digital Diagnostic Monitoring Interface
This section includes the following topics:
Overview of Digital Diagnostic Monitoring Interface
The TXN31015D2 Optical Transceiver supports the 2-wire serial communication
protocol. The TXN31015D2 Optical Transceiver has a digital diagnostic monitoring
interface that is an extension of the serial ID interface defined in the Gigabit Interface
Converter (GBIC) specification and the SFF Transceiver MultiSource Agreement (MSA)

interface, which uses the 8-bit address 1010001X (A2h) reserved for optical
transceivers, allows real-time access to device-operating parameters while leaving
unchanged the original serial ID memory map A0h. The digital diagnostic
monitoring interface is backward compatible with both the GBIC specification and
the SFF MSA.
