11. D ig ital D iag n os ti c Func t i o ns
A-Gear’s SFP 1G CWDM XXch 150LC transceivers support the 2-wire serial
communication protocol as defined in the SFP MSA. 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, A-Gear SFP 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 endusers when particular operating parameters are outside of a factory set normal range.

The SFP MSA defines 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 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,
Mod Def 1) 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, 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.
Digital diagnostics for the SFP 1G CWDM XXch 150LC are internally calibrated by default.
