155M SFP BIDI SC Optical Transceivers


Datacomm’s DC-B0334(43)SC-20 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 FP 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.
