## Summary description

The BlueOptics SFP-BXU34-40KM-AT-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 designed for efficient data transmission over long distances.

## Long description

The BlueOptics SFP-BXU34-40KM-AT-BO is a single-mode fiber optic SFP transceiver module designed for point-to-point links up to 40 km. It supports a maximum data rate of 1250 Mbit/s (1000BASE-BX-U) and uses an LC simplex connector with separate transmit and receive wavelengths (transmit 1490 nm, receive 1310 nm). The module comes in a metal housing for mechanical robustness, offers a compact SFP form factor, and includes digital diagnostics monitoring (DDM/DOM) for real-time measurement of operating parameters.
Advantages
The module provides reliable long-distance 1.25 Gbit/s optical transmission in a compact SFP package while remaining compatible with equipment that supports the 1000BASE-BX-U specification. Metal housing improves durability and thermal behavior, and the included DDM feature enables remote monitoring of voltage, laser bias current, optical output and input power, and temperature. Its low weight and standard SFP interface make it easy to install in switches, routers and other network devices.
Suitable for
 Single-mode fiber point-to-point links up to 40 km
 Gigabit Ethernet (1000BASE-BX-U) connections
 Network equipment requiring LC simplex SFP modules
 Environments where remote optical diagnostics (DDM/DOM) are needed
Key specifications
 Interface type: SFP (small form-factor pluggable)
 Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
 Fiber type: single-mode
 Wavelengths: Tx 1490 nm / Rx 1310 nm
 Connector: LC simplex
 Maximum reach: up to 40 km (dependent on fiber and link budget)
 Diagnostics: DDM / DOM (SFF-8472 compliant)
 Housing: metal
 Weight: approx. 0.02 kg
How to use
Insert the SFP transceiver into a compatible SFP slot on your switch, router or transceiver-capable device while the device is powered down or following the vendor's hot-swap instructions. Connect a single-mode LC simplex patch cord between this transceiver and the corresponding remote transceiver, ensuring correct orientation of transmit and receive fibers. Verify link status in the host device and, if supported, use the digital diagnostics interface to monitor optical power, temperature and supply voltage during commissioning and operation.
Usage recommendations
Use certified single-mode fiber and LC simplex patch cords sized for the 40 km link and verify that both ends use the correct wavelength orientation (Tx/Rx). Confirm that the network hardware supports 1000BASE-BX-U and DDM/DOM to enable full functionality. For improved reliability, operate the module within the host device's recommended temperature range and avoid mechanical stress on fiber connectors.
