## Summary description

The BlueOptics SFP-BXU35-20KM-PS-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 connectivity.

## Long description

The BlueOptics SFP-BXU35-20KM-PS-BO is a single-port SFP fiber-optic transceiver designed for 1000BASE-BX-U applications with a maximum data rate of 1250 Mbit/s. Housed in a metal enclosure and weighing approximately 20 g, this module is intended for single-mode fiber links with LC simplex connector, supporting unidirectional transmit and receive wavelengths suitable for up to 20 km reach. The module implements industry-standard SFP electrical and mechanical interfaces for compatibility with network switches, routers and storage systems that accept MSA-compliant SFP modules.
Advantages
The module offers stable 1.25 Gbit/s performance over single-mode fiber and a compact SFP form factor that fits a wide range of network devices. A metal housing provides mechanical robustness and thermal stability, while the specified MTBF of 1,000,000 hours indicates long-term reliability for continuous operation. Support for digital diagnostics (DDM/DOM) simplifies monitoring of parameters such as supply voltage, laser power and temperature when the host hardware enables this feature.
Suitable for
Single-mode fiber Ethernet links up to 20 km
Interconnects between switches, routers and storage systems
Carrier and enterprise networks requiring 1000BASE-BX-U
Applications that need real-time optical diagnostics (DDM/DOM) support
Key specifications
Form factor: SFP (Small Form-factor Pluggable)
Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
Fiber type: single-mode fiber
Connector: LC simplex
Wavelength: separate transmit and receive wavelengths for 1000BASE-BX-U (typical 1310 nm/1550 nm pairing)
Maximum reach: up to 20 km
Housing material: metal
Color: silver
Weight: approx. 0.02 kg
MTBF: 1,000,000 hours
How to use
Insert the BlueOptics SFP-BXU35-20KM-PS-BO module into an available SFP slot on the host device while the device is powered on or according to the host vendor's hot-plug recommendations. Connect LC simplex single-mode patch cords to the module’s transmit and receive ports, observing correct fiber polarity and the unidirectional nature of 1000BASE-BX-U links. Ensure the host device is configured for a 1.25 Gbit/s SFP module and that any required firmware or software settings allow third-party transceivers if applicable. If monitoring is required, enable DDM/DOM functions in the host to read diagnostic parameters.
Usage recommendations
Use factory-tested single-mode LC patch cords and follow proper fiber handling procedures to maintain link quality. Confirm compatibility with the host hardware documentation before deployment and perform link validation tests after installation to verify expected throughput and DDM readings.
