2.5G SFP CWDM Optical Transceivers


Datacomm’s 2.5G SFP CWDM optical transceivers use the same Small Form Factor Pluggable (SFP) optics form factors and they are 2.5G SFP CWDM optical transceivers that are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). These optical transceivers consists of five sections: the LD driver, the limiting amplifier, the digital diagnostic monitor, the XXnm DFB laser and the PIN photo-detector. The module data link of these 2.5G SFP CWDM optical transceivers range from 40KM to 120KM in 9/125um single mode fiber. The optical output of these 2.5G SFP CWDM optical transceivers 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.
