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

The BlueOptics SFP-BXU34-40KM-LC-BO is a single‑mode fiber optic SFP transceiver module designed for 1000BASE‑BX‑U links with an operational data rate up to 1250 Mbit/s. Housed in metal and weighing approximately 20 g, the module supports simplex LC connections and is specified for long‑reach links up to 40 km. It implements single‑fiber bidirectional transmission with separate transmit and receive wavelengths and includes digital diagnostics monitoring (DDM) for real‑time status reporting when supported by host hardware.

Advantages

The module follows MSA SFP mechanical and electrical standards to ensure interoperability with compatible network equipment and offers a compact metal housing for thermal stability and electromagnetic shielding. With an MTBF around 1,000,000 hours and lightweight construction, it provides a balance of reliability and easy installation. Built for single‑mode fiber and LC simplex connectors, it enables long‑distance Gigabit Ethernet links while providing DDM/DOM data for remote monitoring and maintenance.

Key specifications

How to use

Install the SFP transceiver into a compatible SFP slot on switches, routers or other network devices while the device is powered according to the vendor’s instructions for hot‑swapping if supported. Connect a single‑mode LC simplex patch cable between this transceiver and a corresponding BX‑U transceiver at the remote end, ensuring the correct TX/RX orientation. Verify link status and, if available, use the DDM/DOM information from the host to monitor supply voltage, laser current, optical transmit/receive power and module temperature.

Recommendations

Confirm that the target hardware supports 1000BASE‑BX‑U SFP modules and DDM if remote diagnostics are required. Use single‑mode fiber with appropriate loss budget for 40 km links and high‑quality LC simplex patch cords; avoid excessive bending and inspect connectors for cleanliness before mating to ensure optimal performance.
