PRODUCT DESCRIPTION
Hilink’s 1.25G BIDI SFP 20KM Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA),The transceiver consists of four sections: the LD driver, the limiting amplifier, the 1310nm FP laser(the 1550nm DFB 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 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.
