Glasvezel-transceiver BlueOptics R9F90A-BO 25000 Mbit/s SFP28 850 nm

The BlueOptics R9F90A-BO is a fiber optic transceiver module in SFP28 form factor engineered for 25 Gbit/s connectivity. Operating at an 850 nm wavelength, this module supports high-speed short-reach links over multimode fiber. Housed in a durable metal casing and powered by a standard 3.3 V supply, the transceiver is designed for compact installation in network switches, servers and compatible SFP28 ports. The product’s silver finish and 20 g weight make it a lightweight, rack-friendly component for data centre and enterprise environments.

Advantages

The module offers a 25 000 Mbit/s data transfer rate in the SFP28 form factor, enabling higher throughput compared with older SFP modules while remaining compatible with SFP28 ports. Its 850 nm wavelength is suited for multimode fiber links, providing reliable short-reach performance. A metal housing provides mechanical protection and EMI resilience. The compact and lightweight design simplifies installation in dense networking equipment and helps maintain airflow in rack-mounted systems.

Key specifications

How to use

Ensure the host device supports SFP28 transceivers and 25 Gbit/s operation. With the host powered down or per the device hot-swap procedure, insert the BlueOptics R9F90A-BO into an available SFP28 port until it latches. Connect the appropriate multimode fiber patch cable to the transceiver’s optical interface. Power on the host or allow the port to negotiate link parameters; verify link status through the switch or server management interface. Monitor temperature and signal metrics where supported to ensure stable operation.

Recommendations

Use OM3 or OM4 multimode fiber for optimal short-reach performance at 850 nm, and follow the host vendor’s compatibility list where available. Keep fiber connectors clean and avoid excessive bending of the patch cords. For high-density deployments, allow adequate airflow and verify that power and thermal conditions meet device specifications.
