## Summary description

The BlueOptics SFP-BXU34-20KM-NG-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-BXU34-20KM-NG-BO is a single-mode fiber SFP transceiver module designed for up to 1250 Mbit/s data rate and point-to-point links of up to 20 km. The module is built in a metal housing, weighs approximately 20 g and implements LC simplex connectivity. It supports 1000BASE-BX-U operation with a transmitting wavelength around 1490 nm and receiving wavelength around 1310 nm, and includes Digital Diagnostics Monitoring (DDM) for real-time status of key optical parameters. The product follows MSA SFP mechanical and electrical standards to ensure interoperability with compatible network hardware.
Advantages
The transceiver offers a compact SFP form factor and metal housing for mechanical stability and thermal dissipation. With a rated MTBF of 1,000,000 hours and the use of proven optical and IC components, it provides long operational availability for carrier and enterprise networks. The integrated DDM/DOM support simplifies monitoring and maintenance by reporting supply voltage, laser bias current, output power, received power and temperature when supported by the host device.
Suitable for
 Point-to-point Gigabit Ethernet links over single-mode fiber up to 20 km
 Interconnects between switches, routers and storage systems that accept 1000BASE-BX-U SFP modules
 Upgrades or replacements in network equipment that require LC simplex single-mode transceivers
 Environments where remote optical diagnostics (DDM) are useful for monitoring link health
Key specifications
 Interface type: SFP (MSA compliant)
 Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
 Fiber type: single-mode
 Wavelengths: Tx ≈1490 nm / Rx ≈1310 nm (1000BASE-BX-U)
 Connector: LC simplex
 Maximum distance: up to 20 km (depending on fiber and link budget)
 Housing: metal
 Weight: approx. 0.02 kg
 Digital Diagnostics Monitoring: supported (DDM/DOM, SFF-8472)
 MTBF: approx. 1,000,000 hours
How to use
Install the SFP transceiver into a compatible SFP port on your switch, router or other network device while the host device is powered according to the vendor instructions. Connect a single-mode LC simplex patch cable between this transceiver and the corresponding remote transceiver; ensure correct orientation for the BX-U (bidirectional) link so that the Tx wavelength on one end matches the Rx wavelength on the other end. Verify link status and, if available, read DDM parameters through the host device management interface to confirm optical power levels and temperature within expected ranges.
Usage recommendations
Use factory-quality single-mode patch cords and follow fiber handling best practices (avoid tight bends, keep connectors clean). Confirm host device compatibility with 1000BASE-BX-U SFP modules and enable DDM/DOM support in the management interface if remote diagnostics are required. For critical links, test the module in your specific hardware prior to deployment to validate interoperability and link budget.
