    Frequently Asked Questions (FAQ)

    What is the data rate and connector type for these SFP GE modules?

    All SFP GE models listed in the ordering information support a standard data rate of 1.25G and are designed with LC duplex connectors for reliable fiber connectivity.

    What transmission distances do these SFP modules cover?

    These SFP modules cover a wide range of network distances, starting from 550 meters (multi-mode fiber) up to long-range options of 10km, 20km, 40km, 80km, 120km, and up to 160km (single-mode fiber).

    What laser and receiver types are utilized in the long-distance models?

    For medium distances (up to 80km), DFB+PIN configurations are utilized. For ultra-long distances (120km and 160km), high-performance DFB+APD configurations are deployed to ensure superior receiver sensitivity.

    What is the operating temperature range for these transceivers?

    The standard operating temperature range for these SFP GE optical transceivers is commercial grade, spanning from 0°C to 70°C.

    How can I access the detailed specifications for a specific part number?
