## Summary description

The BlueOptics SFP-BXU35-40KM-NA-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-NA-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 metal and weighing approximately 20 g, this compact SFP module provides a duplex-capable link using an LC simplex connector and supports long-reach transmission up to 40 km with separate transmit and receive wavelengths (TX 1550 nm / RX 1310 nm). The module follows MSA SFP form-factor standards and includes Digital Diagnostic Monitoring (DDM/DOM) support when the host hardware provides the required interface.
Advantages
The transceiver offers stable single-mode optical transmission for Ethernet and related protocols at up to 1.25 Gbit/s over distances to 40 km, with an MTBF rating of 1,000,000 hours indicating long operational life. Its metal housing and standardized SFP interface ensure mechanical robustness and wide interoperability with equipment that accepts MSA-compliant SFP modules. Integrated DDM/DOM support enables real-time monitoring of parameters such as optical output power and temperature when used with compatible systems.
Suitable for
Long-distance single-mode fiber Ethernet links up to 40 km
Switches, routers and storage systems with SFP ports supporting 1000BASE-BX-U
Environments requiring DDM/DOM monitoring for optical diagnostics
Network upgrade or replacement of aging 1 Gbit/s fiber modules
Key specifications
Interface type: SFP (MSA compliant)
Standard: 1000BASE-BX-U
Maximum data transfer rate: 1250 Mbit/s
Wavelengths: TX 1550 nm / RX 1310 nm (single-mode)
Connector: LC simplex
Maximum reach: up to 40 km (single-mode fiber)
Housing: metal
Weight: approx. 0.02 kg
Digital Diagnostic Monitoring (DDM/DOM): supported when host provides interface
MTBF: 1,000,000 hours
How to use
Install the BlueOptics SFP-BXU35-40KM-NA-BO into an empty SFP port on a compliant switch, router or storage device while the host system is powered off or following the vendor’s hot-plug instructions. Connect a single-mode LC patch cable to the LC simplex connector and route the fiber to the remote transceiver; ensure TX of one end is connected to RX of the other end. Configure the host port for 1000BASE-BX-U operation as required by the hardware vendor and verify link status. If available, enable DDM/DOM in the management interface to monitor optical parameters remotely.
Usage recommendations
Use single-mode fiber rated for long-reach links and LC simplex connectors to achieve the specified 40 km range. Verify compatibility with the specific hardware platform and firmware version, and test a sample module in your environment before large deployments. Maintain proper fiber handling and cleanliness for optimal optical performance.
