Digital Diagnostics Functions
MRV’s SFP-10GD-SX SFP+ transceivers support the 2-wire serial communication protocol as defi ned in the SFF-8472. It is very closely
related to the E2PROM defi ned in the GBIC standard, with the same electrical specifi cations.
The standard SFP+ serial ID provides access to identifi cation information that describes the transceiver’s capabilities, standard
interfaces, manufacturer, and other information.
Additionally, MRV’s SFP+ transceivers provide an enhanced Digital Diagnostic monitoring interface that allows real-time access to
device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power,
and transceiver supply voltage. It also defi nes a sophisticated system of alarm and warning fl ags that alert end-users when particular
operating parameters are outside of a factory set normal range.
SFF-8472 defi nes a 256-byte memory map in E2PROM that is accessible over a 2-wire serial interface at the 8 bit address 1010000X
(A0h). The Digital Diagnostic monitoring interface uses the 8-bit address 1010001X (A2h), so the originally defi ned serial ID memory
map remains unchanged. The interface is identical to and fully backward compatible with both the GBIC specifi cation and the SFP
Multi Source Agreement.
The operating and diagnostics information is monitored and reported by a Digital Diagnostics Transceiver Controller (DDTC) inside
the transceiver, which is accessed through a 2-wire serial interface. When the serial protocol is activated, the serial clock signal (SCL,
Mod Def 1) is generated by the host. The positive edge clocks data to the SFP transceiver into those segments of the E2PROM that are
not write-protected. The negative edge clocks data from the SFP transceiver. The serial data signal (SDA, Mod Def 2) is bi-directional
for serial data transfer. The host uses SDA in conjunction with SCL to mark the start and end of serial protocol activation. The memories
are organized as a series of 8-bit data words that can be addressed individually or sequentially.
