SFP transceiver module BlueOptics SFP-BXU35-40KM-CO-BO 1250 Mbit/s

The BlueOptics SFP-BXU35-40KM-CO-BO is a single-mode fiber SFP transceiver module designed for 1000BASE-BX-U applications with a maximum data transfer rate of 1250 Mbit/s. Housed in a compact metal enclosure and weighing approximately 20 g, this module supports long-distance optical links up to 40 km using an LC simplex connector. The transceiver integrates receive and transmit wavelengths arranged for bidirectional operation over a single fiber and is engineered to meet MSA interoperability guidelines for plug-and-play use in compatible network equipment.

Advantages

The metal housing provides mechanical durability and thermal stability for consistent operation in standard networking environments. With a rated mean time between failures (MTBF) of 1,000,000 hours, the module is intended for long service life and reduced maintenance intervals. Compliance with SFP MSA electrical and mechanical specifications ensures wide compatibility with switches, routers and other SFP-supporting devices. The module supports Digital Diagnostic Monitoring (DDM/DOM) for real-time monitoring of optical power, temperature and supply parameters when used in hardware that exposes these diagnostics.

How to use

Install the SFP-BXU35-40KM-CO-BO into an SFP-capable port on compatible network equipment while the device is powered down or following the equipment manufacturer's hot-plug procedures. Connect an appropriate single-mode LC simplex patch cable or a fiber patch panel configured for bidirectional operation. Verify link status and, if available, read DDM values from the host system to confirm transmit and receive power, temperature and supply voltage. Ensure the remote end uses the complementary BX-U transceiver with matching wavelength orientation for correct bidirectional operation.

Recommendations

Use single-mode fiber of appropriate attenuation and quality to achieve the specified 40 km reach, and perform optical power budget calculations when planning links. Confirm that the host hardware supports DDM/DOM if you require diagnostic monitoring. For replacement or interoperability, match the 1000BASE-BX-U profile and LC simplex connector type to the existing infrastructure.
