Kexint BIDI-1.25G-1310/1550nm-10km-LC-DDM 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 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.
