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

The BlueOptics SFP-BXU35-40KM-QN-BO is a single-mode fiber SFP transceiver module designed for up to 1250 Mbit/s data transfer. The module is housed in metal, has a compact SFP form factor with an LC simplex interface and a weight of approximately 20 g. It supports 1000BASE-BX-U operation with a transmitter and receiver pair optimized for single-fiber bi-directional links, providing reliable optical links over distances up to 40 km and featuring an MTBF of 1,000,000 hours.

Advantages

The module follows MSA SFP standards for mechanical and electrical interoperability and includes support for Digital Diagnostics Monitoring (DDM/DOM) where supported by host hardware. Its metal housing contributes to robust mechanical protection and thermal stability. With single-mode LC simplex connectivity and paired wavelengths for transmit and receive, the transceiver enables long-reach point-to-point optical links while maintaining compatibility with major networking platforms that accept MSA-compliant SFP modules.

How to use

Install the module into an available SFP port on compatible network equipment until it latches securely. Connect a single-mode LC simplex fiber patch cord to the transceiver, ensuring the correct orientation for the transmit and receive channels when linking to a complementary BX transceiver at the remote end. Verify that the host device recognizes the module and, if required, enable or confirm DDM/DOM monitoring in the host system to access real-time diagnostics such as optical power and temperature. Follow the equipment manufacturer's procedures for hot-plugging and for confirming link status.

Recommendations

Use high-quality single-mode fiber patch cords and ensure proper cleaning of LC connectors before insertion to maintain optimal optical performance. Confirm that the remote transceiver is configured for the complementary wavelength pair for 1000BASE-BX-U operation and that the host hardware supports SFP modules with DDM if diagnostics are needed. Avoid excessive bending of fiber and protect the module from mechanical shock and contamination during installation and operation.
