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

The BlueOptics SFP-BXU35-20KM-CN-BO is a single-mode fiber SFP transceiver module supporting a maximum data rate of 1250 Mbit/s. Housed in a metal casing and weighing approximately 20 g, this SFP module is designed for point-to-point fiber links up to 20 kilometres and follows MSA mechanical specifications. It implements a bidirectional 1000BASE-BX-U optical interface using LC simplex connectors with separate transmit and receive wavelengths for single-fibre operation.

Advantages

The module provides a compact, hot-pluggable SFP form factor compatible with network devices that support 1000BASE-BX-U optics. A metal housing offers mechanical robustness and thermal dissipation, while a mean time between failures (MTBF) of 1,000,000 hours indicates long operational life for reduced maintenance. Compliance with industry MSA standards ensures interoperability with switches, routers and other SFP-capable equipment, and the design supports Digital Diagnostics Monitoring when the host platform provides DDM/DOM support.

Key specifications

How to use

Insert the SFP transceiver into any compatible SFP slot on a switch, router or other network device while the host is powered on or according to the device manufacturer’s hot-swap guidance. Connect an appropriate single-mode LC simplex patch cable between this transceiver and the remote transceiver, ensuring correct orientation of transmit and receive ends for BX-U operation. Verify link negotiation and speed settings on both ends and enable DDM/DOM in the host system if monitoring of optical parameters is required.

Recommendations

For best performance, use single-mode fiber and LC simplex patch cords rated for 1310/1550 nm, keep connectors clean and install transceivers in equipment that officially supports 1000BASE-BX-U SFP modules. Confirm that the host device supports DDM/DOM if you require real-time diagnostics, and follow the equipment manufacturer’s thermal and handling guidelines to maintain the stated MTBF and operational stability.
