Brand : D-TECH
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 FP laser and the PIN photo-detector .The module data link up to 20km 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 can also disable the module via I2C. Tx Fault is provided to indicate the degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal from the receiver or the link status with the partner. The system can also get the LOS (or link) or disable/fault information via I2C register access.
It has to be noted that the operation in excess of any individual absolute maximum ratings might cause permanent damage to this module
