General Description
HTF DWDM 2.5G 160km Module transceivers include an APD photo-detector diode and temperature stabilized DWDM EML transmitter. Digital diagnostic functions are available via an I2C.This module is designed for single mode fiber and operates at a nominal wavelength of 100GHz ITU Grid,C Band DWDM wavelength. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF8472.
The optical output can be disabled by a TTL logic high-level input of Tx Disable,and the system also can disable the module via I2C. Tx Fault is provided to indicate that degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of receiver or the link status with partner. The system can also get the LOS (or Link)/Disable/Fault information via I2C register access.
