SFP-lähetin-vastaanotinmoduuli BlueOptics SFP-BXU35-20KM-CO-BO 1250 Mbit/s

The BlueOptics SFP-BXU35-20KM-CO-BO is a single-mode SFP transceiver module designed for fiber-optic links with a maximum data transfer rate of 1250 Mbit/s. Housed in a metal enclosure and weighing approximately 20 g, the module supports point-to-point optical connections over distances up to 20 km using LC simplex connection and complies with MSA mechanical standards. It is intended for use in network equipment that accepts SFP 1000BASE-BX-U optics and provides stable long-distance connectivity with an MTBF of around 1,000,000 hours.

Advantages

The module offers a compact, metal-bodied design for reliable mechanical protection and thermal dissipation. It supports 1000BASE-BX-U operation with separate transmit and receive wavelengths suitable for single-fiber, bidirectional links. Digital Diagnostics Monitoring (DDM/DOM) support enables remote monitoring of parameters such as supply voltage, laser bias current, optical output/input power and temperature when the host supports these functions. Compliance with SFP MSA ensures electrical and mechanical interoperability with SFP-enabled hardware from multiple vendors.

How to use

Install the SFP transceiver into an empty SFP port on a compatible switch, router or network device while the host device is powered according to the vendor’s instructions. Use a single-mode LC simplex patch cable or patch panel to connect the module to the remote transceiver; ensure the correct fiber polarity for a BX-U link (TX of one end to RX of the other). If the host and module support DDM/DOM, enable and monitor diagnostic parameters through the device management interface to verify link health. Follow the equipment manufacturer’s recommendations for hot-plugging and handling to avoid electrostatic or mechanical damage.

Recommendations

Verify firmware and hardware compatibility with your network device before deployment, use suitable single-mode patch cables and fiber connectors, and perform link tests after installation. For remote monitoring, confirm DDM/DOM support in the host system to access real-time diagnostic values.
