## Summary description

The BlueOptics SFP-BXU35-40KM-QL-BO is a fiber optic SFP transceiver module with a maximum data transfer rate of 1250 Mbit/s. It features a metal housing, weighs 20 g, and has an MTBF of 1,000,000 hours, making it a reliable choice for network applications.

## Long description

The BlueOptics SFP-BXU35-40KM-QL-BO is a single-mode fiber optic SFP transceiver designed for 1000BASE-BX-U applications with a maximum data rate of 1250 Mbit/s. The module features an LC simplex connector, metal housing in silver colour, low weight (0.02 kg) and an MTBF of 1,000,000 hours, providing a compact, standard-compliant option for point-to-point links up to 40 km when paired with appropriate single-mode fiber.
Advantages
This SFP transceiver follows MSA standards for form factor and interoperability, enabling broad compatibility with network switches, routers and storage systems that support 1000BASE-BX-U modules. It supports bidirectional transmission over a single fiber using separate wavelengths (receiver and transmitter), and offers digital diagnostics (DDM/DOM) for remote monitoring of supply voltage, laser bias current, transmit power, receive power and temperature where supported by host hardware. The metal housing and tested components contribute to long operational life and stable optical performance.
Suitable for
 Single-mode point-to-point Ethernet links up to 40 km
 Interoperable use in switches, routers and storage arrays supporting 1000BASE-BX-U
 Long-distance fiber connections in campus and metropolitan networks
 Environments where DDM/DOM monitoring is required for link diagnostics
Key specifications
 Interface type: SFP (LC simplex)
 Protocol: 1000BASE-BX-U (bidirectional over single-mode fiber)
 Wavelength: Tx 1550 nm / Rx 1310 nm (bidirectional operation)
 Maximum data transfer rate: 1250 Mbit/s
 Maximum reach: up to 40 km on single-mode fiber (typical)
 Housing: metal, silver colour
 Weight: 0.02 kg
 Digital diagnostics: DDM/DOM support (if host supports feature)
 MTBF: 1,000,000 hours
How to use
Install the SFP-BXU35-40KM-QL-BO transceiver into an SFP port on a compatible switch, router or storage device while the host is powered according to the vendor’s hot-plug guidelines. Use an LC simplex single-mode patch cord and ensure the remote transceiver is configured for complementary wavelengths (one end Tx 1550 / Rx 1310, the other end Tx 1310 / Rx 1550) to establish a bidirectional link on a single fiber. Verify link status in the host device and enable DDM/DOM monitoring in the management interface if available for real-time diagnostics.
Usage recommendations
To achieve the specified reach and stable performance, use ITU-T G.652-compliant single-mode fiber and high-quality LC connectors, avoid excessive bends and maintain clean fiber end faces. Confirm host compatibility and firmware support for third-party SFP modules and enable DDM only if the host reports correct diagnostic values.
