## Summary description

The BlueOptics SFP-BXU34-20KM-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. Ideal for reliable network connections over long distances.

## Long description

The BlueOptics SFP-BXU34-20KM-NA-BO is a single-mode fiber SFP transceiver module designed for 1000BASE-BX-U links with a maximum data transfer rate of 1250 Mbit/s. Housed in a metal enclosure and weighing 20 g, the module supports point-to-point optical connections over distances up to 20 km using an LC simplex connector. It implements MSA-compliant electrical and mechanical interfaces for broad interoperability and offers an MTBF of 1,000,000 hours for long operational life.
Advantages
The BlueOptics SFP-BXU34-20KM-NA-BO provides DDM/DOM-capable monitoring for real-time diagnostics of supply voltage, temperature, laser bias current, transmit power and receive power. The module is manufactured to MSA standards for plug-and-play compatibility with equipment that supports 1000BASE-BX-U SFP transceivers. Its metal housing ensures mechanical robustness while the single-mode LC simplex interface allows simultaneous transmit and receive over separate wavelengths (1310 nm receive / 1490 nm transmit) on a single fiber.
Suitable for
 Long-distance single-mode Ethernet links up to 20 km
 Interconnects between switches, routers and storage systems
 Fibre Channel over Ethernet (FCoE) and SDH/SONET applications at 1.25 Gbit/s
 Environments requiring remote optical link diagnostics (DDM/DOM)
Key specifications
 Interface type: SFP (MSA compliant)
 Nominal data rate: 1250 Mbit/s (1000BASE-BX-U)
 Optical mode: Single-mode fiber
 Wavelengths: Tx 1490 nm / Rx 1310 nm (bi-directional on one fiber)
 Connector: LC simplex
 Maximum reach: up to 20 km (single-mode fiber)
 Housing: metal
 Weight: 0.02 kg
 MTBF: 1,000,000 hours
 Digital diagnostic monitoring (DDM/DOM): supported (if host supports feature)
How to use
Insert the SFP module into a compatible SFP slot on the network device until it latches. Use an LC simplex single-mode patch cable to connect the transmitter and receiver ends; observe the correct orientation for the BX-U pair where one module transmits at 1490 nm and receives at 1310 nm while its counterpart uses the complementary wavelengths. Verify host compatibility and enable DDM/DOM in the managing system if you require live diagnostics. Follow standard ESD precautions when handling the module and keep dust caps on unused ports.
Usage recommendations
For reliable performance, use single-mode fiber of appropriate quality and ensure end-to-end loss budgets are within the module's specifications. Confirm device compatibility with 1000BASE-BX-U operation and enable digital diagnostics on supported hardware to monitor link health. Store and install the transceiver in environments that meet manufacturer temperature and humidity ranges and avoid mechanical stress to fiber connectors.
