Digital Diagnostic Functions
TOPSTAR TOP-SFP+-10G-LRM transceivers support the 2-wire serial communication protocol as defined in the SFP
MSA1.
The standard SFP serial ID provides access to identification information that describes the transceiver’s
capabilities, standard interfaces, manufacturer, and other information.
Additionally, TOPSTAR 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 end-users when particular operating parameters
are outside of a factory set normal range.
The SFP MSA defines a 256-byte memory map in EEPROM 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 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
