2.5G SFP Optical Transceivers


Datacomm’s 2.5G Small Form Factor Pluggable (SFP) optical transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). The 2.5G SFP optical transceivers consist of five sections: the LD driver, the limiting amplifier, the digital diagnostic monitor, the 1310nm FP laser and the PIN photo-detector. The data link of these 2.5G SFP optical modules range from 2KM to 120KM 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.
