## Summary description

The BlueOptics SFP-BXU34-40KM-NG-BO is a fiber optic SFP transceiver module with a maximum data transfer rate of 1250 Mbit/s. It features a metal housing and has a mean time between failures (MTBF) of 1,000,000 hours. Weighing 20 g, it is designed for reliable network connections over long distances.

## Long description

The BlueOptics SFP-BXU34-40KM-NG-BO is an SFP fiber-optic transceiver module designed for single-mode links with a maximum data rate of 1250 Mbit/s. The module has a metal housing, a compact SFP form factor and a low weight of 20 g, making it suitable for use in switches, routers and other network devices that accept SFP optics. It supports LC simplex connections and is intended for long-distance optical links up to 40 km with separate transmit and receive wavelengths (bidirectional over a single fiber).
Advantages
The module offers a standardized SFP interface and MSA-compliant mechanical and electrical characteristics for broad interoperability with third-party hardware. With a mean time between failures (MTBF) of 1,000,000 hours and metal housing construction, it is designed for continuous operation and stable thermal performance. Digital Diagnostics Monitoring (DDM/DOM) support enables remote monitoring of key optical and electrical parameters when the host hardware provides that feature.
Suitable for
Single-mode fiber links up to 40 km
Gigabit Ethernet and related 1.25 Gbit/s applications
Interconnects between switches, routers, storage systems and media converters
Environments requiring LC simplex connectors and bidirectional single-fiber transmission
Key specifications
Interface type: SFP (Small Form-factor Pluggable)
Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
Fiber type: single-mode fiber (SMF)
Maximum reach: up to 40 kilometers on single-mode fiber
Wavelength: separate transmit and receive wavelengths for bidirectional operation over one fiber
Connector: LC simplex
Housing: metal
Weight: 0.02 kg
Digital Diagnostics Monitoring (DDM/DOM): supported where host hardware provides access
How to use
Install the SFP transceiver in an appropriate SFP slot of a compatible network device until it latches; ensure the host device supports the SFP form factor and the required Ethernet protocol. Connect an LC simplex single-mode patch cable to the module and route the fiber to the corresponding transceiver at the remote end, ensuring correct orientation of transmit and receive fibers for bidirectional operation. If your host supports DDM/DOM, enable or query the diagnostics interface to monitor supply voltage, laser bias current, transmit power, receive power and module temperature. Follow standard electrostatic discharge (ESD) precautions during handling and avoid bending the fiber beyond its minimum bend radius.
Usage recommendations
Use certified single-mode LC simplex patch cords and compatible SFP ports for reliable operation. Verify that the host device supports bidirectional single-fiber (BX) transceivers and DDM/DOM if online diagnostics are required. Maintain clean fiber end-faces and observe manufacturer guidelines for insertion/removal to preserve long-term performance.
