General Description
F-tone Networks'FTCS-Cxx12-H6Dxx Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA),The transceiver consists of five sections: the LD driver,the limiting amplifier,the digital diagnostic monitor,the CWDM DFB laser and the APD photo-detector .The module data link up to 160km in 9/125um single mode fiber.
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.
