HTF's HTSX-B273396Lx / HTSX-B332796Lx SFP+ transceiver is designed for use in 10-
Gigabit Ethernet links up to 10 km over single-mode fiber. The module consists of CWDM and DFB
Laser, PIN and Preamplifier in a high-integrated optical sub-assembly. Digital diagnostics
functions
are available via a 2-wire serial interface, as specified in SFF-8472. HTSX-B273396Lx
HTSX-B332796Lx transceivers provide 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.
