## Summary description

The BlueOptics SFP-BXU35-40KM-AO-BO is a fiber optic SFP transceiver module with a maximum data transfer rate of 1250 Mbit/s. It features a metal housing for durability and has a mean time between failures (MTBF) of 1,000,000 hours. Weighing only 20 g, it is lightweight and efficient for network applications.

## Long description

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.
Suitable for
Point-to-point single-mode fiber links up to 40 km
Gigabit Ethernet (1000BASE-BX-U) connections
Integration into switches, routers, and storage systems that accept MSA SFP modules
Environments requiring DDM/DOM monitoring for remote diagnostics

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.
Usage 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.
