SFP-transceivermodule BlueOptics SFP-BXU34-40KM-AT-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-40KM-AT-BO is a single-mode fiber optic SFP transceiver module designed for point-to-point links up to 40 km. It supports a maximum data rate of 1250 Mbit/s (1000BASE-BX-U) and uses an LC simplex connector with separate transmit and receive wavelengths (transmit 1490 nm, receive 1310 nm). The module comes in a metal housing for mechanical robustness, offers a compact SFP form factor, and includes digital diagnostics monitoring (DDM/DOM) for real-time measurement of operating parameters.

Advantages

The module provides reliable long-distance 1.25 Gbit/s optical transmission in a compact SFP package while remaining compatible with equipment that supports the 1000BASE-BX-U specification. Metal housing improves durability and thermal behavior, and the included DDM feature enables remote monitoring of voltage, laser bias current, optical output and input power, and temperature. Its low weight and standard SFP interface make it easy to install in switches, routers and other network devices.

Key specifications

How to use

Insert the SFP transceiver into a compatible SFP slot on your switch, router or transceiver-capable device while the device is powered down or following the vendor's hot-swap instructions. Connect a single-mode LC simplex patch cord between this transceiver and the corresponding remote transceiver, ensuring correct orientation of transmit and receive fibers. Verify link status in the host device and, if supported, use the digital diagnostics interface to monitor optical power, temperature and supply voltage during commissioning and operation.

Recommendations

Use certified single-mode fiber and LC simplex patch cords sized for the 40 km link and verify that both ends use the correct wavelength orientation (Tx/Rx). Confirm that the network hardware supports 1000BASE-BX-U and DDM/DOM to enable full functionality. For improved reliability, operate the module within the host device's recommended temperature range and avoid mechanical stress on fiber connectors.
