SFP transceiver module BlueOptics SFP-BXU35-20KM-NA-BO 1250 Mbit/s

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.

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.

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.
