Modulo ricetrasmettitore SFP BlueOptics SFP-BXU34-40KM-SW-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-40KM-SW-BO is a single-mode fiber SFP transceiver module designed for 1000BASE-BX-U applications with a maximum data rate of 1250 Mbit/s. Housed in metal and weighing 20 g, this compact SFP module supports LC simplex connections and is intended for long-reach fiber links up to 40 km when used in appropriate network equipment. The transceiver implements single-fiber bidirectional transmission with separate transmit and receive wavelengths and is compliant with common SFP MSA form-factor requirements.

Advantages

The module offers compatibility with SFP ports that support 1000BASE-BX-U protocols and is built to deliver stable optical links with an MTBF of 1,000,000 hours. The metal housing provides mechanical robustness and electromagnetic shielding while the lightweight design simplifies installation in switches, routers and media converters. Digital diagnostic monitoring (DDM/DOM) support is typically available on this class of transceivers to enable remote measurement of parameters such as optical power and temperature, facilitating easier maintenance and monitoring.

Key specifications

How to use

Insert the SFP transceiver into a compatible SFP port on your switch, router or media converter while the device is powered down or following the vendor's hot-plug guidance. Connect a single-mode LC simplex fiber patch cord between transceivers or to a patch panel, ensuring the correct orientation for transmit and receive fibers according to BX-U wavelength assignment. Verify link status and, where available, monitor diagnostics via the host device to confirm optical power levels and temperature are within expected ranges. Follow the network equipment vendor's firmware and configuration recommendations for enabling 1000BASE-BX-U operation.

Recommendations

Use high-quality single-mode fiber and LC simplex patch cords and confirm that the host hardware supports BX-U single-fiber transceivers and DDM/DOM if you require remote diagnostics. Avoid bending the fiber beyond its minimum bend radius and keep connectors clean to maintain optimal signal levels and reliable 40 km operation.
