SFP transceiver module BlueOptics SFP-LHX1310-40-BO 1250 Mbit/s 1310 nm

The BlueOptics SFP-LHX1310-40-BO is a single‑mode fiber optic SFP transceiver module designed for 1000BASE‑LH applications. It supports a maximum data transfer rate of 1250 Mbit/s at a wavelength of 1310 nm, features an LC duplex optical connector and a metal housing for mechanical durability. The module operates from a 3.3 V supply and weighs approximately 3 g, providing a compact, hot‑pluggable solution for extending optical links up to 40 km when used with appropriate single‑mode fiber.

Advantages

The module offers a standard SFP form factor that ensures compatibility with a wide range of network devices that support 1000BASE‑LH transceivers. Its metal housing contributes to mechanical robustness and thermal stability while the single‑mode 1310 nm optical interface enables long‑reach connections. Support for common digital diagnostics (when host hardware supports DDM/DOM) allows monitoring of parameters such as supply voltage, laser bias current, transmit power, receive power and temperature.

How to use

Install the BlueOptics SFP‑LHX1310‑40‑BO into an empty SFP slot on compatible network equipment while the host device is powered or supports hot‑swapping. Connect LC duplex single‑mode patch cables to the module’s transmit and receive ports, ensuring correct fiber polarity. Verify link status in the host device and, if available, enable or query digital diagnostics (DDM/DOM) through the network equipment to monitor optical parameters and voltage. Follow the host vendor’s instructions for any required compatibility or firmware settings.

Recommendations

For reliable long‑reach performance, use single‑mode fiber of appropriate attenuation and quality, keep connectors clean and properly mated, and confirm that the host device supports 1000BASE‑LH SFP modules and DDM/DOM if monitoring is required. Avoid exposure to mechanical stress and excessive temperatures to preserve module lifetime.
