Módulo transceptor SFP BlueOptics SFP-BXU34-40KM-PT-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-40KM-PT-BO is a single-mode fiber optic SFP transceiver module designed for 1000BASE-BX-U applications with a maximum data rate of 1250 Mbit/s. Housed in a durable metal case and weighing just 20 g, this module supports long-distance optical links up to 40 km using LC Simplex connectors. The module implements separate wavelengths for transmit and receive, enabling bi-directional transmission over a single fiber and is built to industry MSA standards for interoperability.

Advantages

The transceiver provides stable Gigabit connectivity over long single-mode fiber runs while keeping a compact SFP form factor and a metal housing for mechanical durability and EMI resistance. With an MTBF of approximately 1,000,000 hours and support for digital diagnostics monitoring (DDM/DOM), it enables reliable long-term operation and easier remote troubleshooting. The module is compatible with common 1000BASE-BX-U ports and is suitable as a functional replacement in systems that support MSA-compliant SFP modules.

How to use

Insert the BlueOptics SFP-BXU34-40KM-PT-BO into any compatible SFP slot on a switch, router or optical interface following the host device manufacturer’s hot-plug guidelines. Connect an LC Simplex single-mode fiber patch cable between transceivers at each end, ensuring proper alignment of the bi-directional wavelengths (transmit 1490 nm to receive 1490 nm on the opposite end). Verify link negotiation and speed on the host device and, if required, enable DDM/DOM monitoring in the management interface to track parameters such as temperature, supply voltage and optical power levels.

Recommendations

To achieve reliable performance, use single-mode LC patch cords and clean connectors before mating. Confirm compatibility with the host device firmware or vendor compatibility list if the platform enforces vendor checks. When deploying long links, test the optical power budget and enable DDM/DOM monitoring to detect potential degradation early. Store unused modules in anti-static packaging and avoid exposure to moisture or extreme temperatures.
