SFP transceiver modul BlueOptics SFP-BXU35-40KM-AO-BO 1250 Mbit/s

The BlueOptics SFP-BXU35-40KM-AO-BO is a single-mode fiber optic SFP transceiver module designed for 1000BASE-BX-U applications with a maximum data transfer rate of 1250 Mbit/s. Housed in a metal casing and weighing approximately 20 g, the module provides a compact, MSA-compliant SFP interface with LC simplex connectivity. It supports one-way transmit and receive over a single fiber pair with transmitter wavelength at 1550 nm and receiver wavelength at 1310 nm, and is specified for point-to-point links up to 40 km. The transceiver includes digital diagnostics (DDM/DOM) support where the host hardware implements the standard interface, and it is suitable for integration into switches, routers and storage equipment that accept MSA SFP modules.

Advantages

The transceiver combines a robust metal housing with low weight for easy handling and installation. With a high MTBF figure (around 1,000,000 hours) it is designed for long operational availability and reduced maintenance needs. Compliance with MSA mechanical and electrical standards ensures interoperability with a wide range of network hardware that supports 1000BASE-BX-U SFP modules. Built to work with single-mode fiber and LC simplex connectors, the module supports optical links up to 40 km while offering DDM/DOM monitoring for supply voltage, laser bias current, transmit power, receive power and temperature when enabled by the host.

How to use

Install the SFP transceiver into an empty SFP port on compatible network equipment, observing proper ESD precautions. Connect an LC simplex single-mode patch cable between this transceiver and the corresponding remote transceiver; ensure correct orientation for the transmit and receive fibers since this is a bidirectional (BX) module with separate Tx and Rx wavelengths. After insertion, verify link status on the host device and check DDM/DOM readings if the equipment provides this capability. For reliable performance, use appropriate single-mode fiber and ensure connectors and patch cords are clean and undamaged.

Recommendations

Ensure the host device officially supports 1000BASE-BX-U SFP transceivers and DDM/DOM if diagnostics are required. Use high-quality single-mode LC simplex patch cords and follow standard fiber handling procedures, including cleaning connectors before mating and protecting exposed fiber ends. For long-term availability, maintain appropriate operating temperature and avoid mechanical stress on connectors and cables.
