General Description of SFP 10G, BIDI Tx1550nm/Rx1490nm, 80KM, LC DDM:

HTF’HTSX-B495596Zx/HTSX-B554996Zx SFP+ transceiver is designed for use in 10-Gigabit Ethernet links up to 80km over single-mode fiber. The module consists of CWDM DFB Laser, APD and Preamplifier in a highly integrated optical sub-assembly. Digital diagnostic functions are available via a 2-wire serial interface, as specified in SFF-8472.

HTSX-B495596Zx/HTSX-B554996Zx 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
