2.5G SFP DWDM Optical Transceivers


Datacomm’s 2.5G SFP DWDM optical transceivers include a series of the Small Form Factor Pluggable (SFP) transceivers that are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA) and SFF-8472. The 2.5G SFP DWDM optical transceiver consists of five sections: the LD driver, the limiting amplifier, the digital diagnostic monitor, the DFB laser and the APD. These 2.5G SFP DWDM optical modules have a data link up to 80KM and 120KM in 9/125um single mode fiber. Each of the 2.5G SFP DWDM optical transceivers offers a simple and convenient way to interface PCBs to single mode fiber optic cables in Dense Wavelength Division Multiplexing (DWDM) applications. These 2.5G SFP DWDM optical transceivers are high performance, cost effective optical modules for serial optical data communication applications.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.
