## Summary description

The BlueOptics SFP-BXU35-20KM-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 a mean time between failures (MTBF) of 1,000,000 hours, ensuring reliability for network applications.

## Long description

The BlueOptics SFP-BXU35-20KM-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. The module features an LC simplex connector, metal housing in silver, and a compact, lightweight design (approx. 20 g). It supports bidirectional transmission with separate transmit and receive wavelengths and is built to industry MSA standards for broad interoperability with switches, routers and storage systems that accept SFP modules.
Advantages
This SFP transceiver provides long reach capability up to 20 km over single‑mode fiber while maintaining 1.25 Gbit/s throughput. The metal housing offers durable mechanical protection and thermal stability. With a high MTBF (around 1,000,000 hours) and support for digital diagnostics (DDM/DOM) when enabled by the host hardware, the module supports reliable continuous operation and remote monitoring of key parameters such as optical output/input power, temperature and supply voltage.
Suitable for
 Single‑mode fiber networks requiring point‑to‑point 1000BASE‑BX‑U links
 Interconnects between switches, routers and storage systems over distances up to 20 km
 Environments where compact, MSA‑compliant SFP modules are needed for mixed‑vendor equipment
 Installations that benefit from digital diagnostics for remote monitoring and troubleshooting
Key specifications
 Interface type: SFP (LC simplex)
 Transmission standard: 1000BASE‑BX‑U (bidirectional single‑fibre)
 Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
 Optical fiber type: single‑mode fiber
 Wavelengths: separate Tx/Rx wavelengths (bidirectional operation)
 Maximum reach: up to 20 km
 Housing: metal, silver colour
 Weight: approx. 0.02 kg
 Digital diagnostics: DDM/DOM support (requires host support)
 MSA compliance for electrical, mechanical and functional interoperability
How to use
Insert the SFP module carefully into an SFP slot on the target device (switch, router or storage system) until it clicks into place. Connect an LC simplex single‑mode patch cable to the module and to the remote transceiver; ensure correct orientation of transmit and receive fibers for bidirectional links. Verify that the host device recognizes the module and, if available, enable DDM/DOM functions in the management interface to monitor optical and electrical parameters. Follow the equipment manufacturer’s guidance for hot‑swap procedures and electrostatic discharge (ESD) precautions during handling and installation.
Usage recommendations
For optimal performance, use single‑mode LC simplex fiber patch cords rated for the intended distance, keep optical connectors clean, and confirm that the remote end uses a compatible BX‑U transceiver with matching wavelengths. Ensure the host device firmware supports third‑party SFP modules and DDM if remote diagnostics are required. Store unused modules in protective packaging to avoid contamination and mechanical damage.
