SFP transceiver modul BlueOptics SFP-BXU34-40KM-SO-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-40KM-SO-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 transfer rate of 1250 Mbit/s (1000BASE-BX-U) and uses an LC simplex connector for single-fiber bidirectional transmission. The transceiver comes in a metal housing, has a compact SFP form factor, weighs approximately 20 g and is intended for use in network equipment that supports standard MSA-compliant SFP modules.

Advantages

This BlueOptics transceiver provides MSA-compliant electrical and mechanical compatibility with SFP ports and supports Digital Diagnostics Monitoring (DDM/DOM) when the host hardware enables it. The metal housing contributes to mechanical durability and heat dissipation, while the module’s specifications and component selection are intended to deliver long Mean Time Between Failures (MTBF) for stable operation in production networks. Its single-mode 1310 nm/1490 nm wavelength pairing and LC simplex interface allow use in long-reach fiber links with minimal susceptibility to electromagnetic interference.

How to use

Install the SFP transceiver into an MSA-compliant SFP slot of a switch, router or other networking device while the device is powered according to the host manufacturer’s instructions. Connect a single-mode LC simplex fiber patch cable between transceivers at each link end, observing polarity for bidirectional single-fiber operation. Verify link parameters and enable DDM/DOM in the host system if optical diagnostics are required. Follow standard safety and handling procedures for optical modules to avoid ESD damage and protect fiber ends from contamination.

Recommendations

Use matched single-mode patch cords and ensure the link budget (attenuation and connectors) supports the 40 km reach. Confirm that the host device firmware supports 1000BASE-BX-U and DDM/DOM features; if necessary, test the module in your hardware prior to large deployments. Clean connector endfaces before mating and store modules in protective caps when not in use.
