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 VCSEL laser and the PIN photo-detector .The module data link up to 550m in
50/125um multi 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.
