Digital Diagnostic Functions
SFP 1.25G 80KM 1310&1550 transceivers support the 2-wire serial communication protocol as defined in the SFPMSA. It is
very closely related to the E2PROM defined in the GBIC standard, with the same electrical specifications.
The standard SFP serial ID provides access to identification information that describes the transceiver’s capabilities, standard
interfaces, manufacturer, and other information.
Additionally, SFP 1.25G 80KM 1310&1550 transceivers provide a unique enhanced digital diagnostic monitoring interface,
which 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 defines a sophisticated system of alarm and
warning flags, which alerts end-users when particular operating parameters are outside of a factory set normal range.
The SFPMSA defines a 256-byte memory map in E2PROM that is accessible over a 2-wire serial interface at the 8 bit
address1010000X(A0h).The digital diagnostic monitoring interface makes use of the 8 bit address 1010001X(A2h), so the
originally defined serial ID memory map remains unchanged. The interface is identical to, and is thus fully backward
compatible with both the GBIC Specification 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,ModDef1) is generated by the host. The positive edge clocks data into 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,ModDef2) 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 asaseriesof8-bit data words that can be addressed
individually or sequentially.
Digital diagnostics for the TOP-BIDI-1.25G-80AD/BD are Internally calibrated by default.
