    SFP CWDM SFP 2.5G 1330nm 1370nm Module Fiber Optic Transceiver Module 40km

    SFP CWDM SFP 2.5G 1330nm 1370nm Module Fiber Optic Transceiver Module 40km


    2.5Gb/s CWDM Single-mode SFP Transceiver

    SFP-2.5G-CWDM-40km-LC-DDM 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 XXnm DFB laser and the PIN photo-detector .The module data link up to 40KM 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.


    • Up to 2.5Gb/s data links
    • DFB laser transmitter and PIN photo-detector
    • Up to 40km on 9/125µm SMF
    • Hot-pluggable SFP footprint
    • Duplex LC/UPC type pluggable optical interface
