Serial Interface for ID and Digital Diagnostic Monitor

 

The OLSP311XL-C(I)D20T transceiver support the 2-wire serial communication protocol as defined in the SFP+ MSA. The standard SFP+ serial ID provides access to identification information that describes the transceiver's capabilities, standard interfaces, manufacturer, and other information. Additionally, This SFP+ transceivers provide an 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), so the originally monitoring interface makes use of the 8 bit address(A2h), so the originally defined serial ID  memory map remains unchanged. The structure of the memory map is shown in Table1.
 

Digital Diagnostic Specifications

The OLSP311XL-C(I)D20T transceivers can be used in host systems that require either internally or externally calibrated digital diagnostics.
