## Summary description

The BlueOptics SFP-1G-BX40-U-BO is a fiber optic SFP transceiver module designed for long-distance data transmission up to 40000 m. It features an aluminum body and weighs only 20 g, making it lightweight and durable. Ideal for network applications requiring reliable and efficient connectivity.

## Long description

The BlueOptics SFP-1G-BX40-U-BO is a single-mode fiber SFP transceiver designed for one-way 1000BASE-BX-U transmission over long distances up to 40,000 meters. Housed in an aluminium enclosure and weighing approximately 20 g, this compact module provides a standardized SFP interface with LC simplex connector compatible with MSA-compliant ports. The module uses a 1490 nm transmitter and a 1310 nm receiver to carry optical signals on separate wavelengths over a single fiber, enabling long-reach links with low electromagnetic interference.
Advantages
The transceiver supports long-distance single-mode connections up to 40 km while maintaining a small, lightweight aluminium form factor suitable for dense installations. It is built to MSA standards for mechanical and electrical compatibility with a wide range of network equipment. The module implements separate transmit and receive wavelengths for single-fiber operation and optionally supports Digital Diagnostics Monitoring (DDM/DOM) when the host device provides the required interface, enabling remote monitoring of voltage, temperature, laser bias current and optical power.
Suitable for
Long-distance fiber links between buildings or data centers
Upgrading switches and routers to support 1000BASE-BX-U single-mode connections
Optical backbone segments in campus and metropolitan area networks
Applications requiring low EMI and stable throughput over single-mode fiber
Key specifications
Interface type: SFP (MSA compliant)
Data rate: 1.25 Gbps (1000BASE-BX-U)
Fiber type: Single-mode fiber
Wavelengths: Tx 1490 nm / Rx 1310 nm
Connector: LC simplex
Maximum reach: up to 40,000 m (40 km)
Housing: aluminium
Weight: approx. 0.02 kg
Support for Digital Diagnostics Monitoring (DDM/DOM) when supported by host hardware
How to use
Insert the SFP module into an empty SFP slot of a compatible switch, router or other network device while the device is powered according to the vendor guidance. Use an LC simplex single-mode patch cord or patch panel to connect the module to the remote transceiver; note that this module uses different wavelengths for transmit and receive, so the transmit fiber of one end must connect to the receive fiber of the other end. If the host device supports DDM/DOM, enable or query the diagnostic interface through the device management system to monitor operational parameters. Follow your equipment vendor’s instructions for hot-plugging and firmware compatibility checks.
Usage recommendations
For reliable long-distance links, pair the module with single-mode OS2-rated fiber and quality LC connectors, maintain correct fiber polarity (Tx↔Rx), and confirm that the host hardware supports 1000BASE-BX-U and, if required, DDM/DOM. Avoid excessive bending of fiber cables and protect transceiver modules from dust when not connected.
