SFP transceiver module BlueOptics TN-SFP-25G-SR-S-BO 25000 Mbit/s 850 nm

The BlueOptics TN-SFP-25G-SR-S-BO is an SFP28 fiber-optic transceiver module designed for 25GBASE-SR short-range optical links. It supports a maximum data transfer rate of 25,000 Mbit/s over multimode fiber at an operating wavelength of 850 nm. The module has a metal housing in silver color, accepts 3.3 V input voltage, features an LC duplex interface via an SFP28 form-factor connector and is specified for reach up to 100 meters. Lightweight and compact, it is intended for insertion into compatible switch, router or storage system ports that support SFP28 25GBASE-SR optics.

Advantages

The transceiver provides high-speed 25 Gbit/s optical connectivity using standardized SFP28 form factor and LC duplex connection, enabling simultaneous transmit and receive over two fibers. Its metal housing ensures mechanical robustness and thermal stability, while the 3.3 V operation matches common transceiver power rails. The module is compatible with multimode fiber links up to 100 m and is lightweight for easy handling and installation. Digital diagnostics/DOM support allows monitoring of supply voltage, laser bias, optical power and temperature when the host hardware provides the diagnostic interface.

Key specifications

How to use

Verify that your host device (switch, router or storage system) supports SFP28 25GBASE-SR modules and the Digital Diagnostics Monitoring (DDM/DOM) interface if you intend to use diagnostics. With power off or according to the host manufacturer’s hot-swap instructions, insert the SFP28 transceiver into an available SFP28 slot until it latches. Connect LC duplex multimode fiber patch cords, ensuring correct polarity for transmit and receive pairs and using appropriate MPO/patch panel routing where applicable. Power on the host and confirm link status via the device management interface. Use supported fiber patch cords and proper fiber handling practices to maintain signal quality and link reach.

Recommendations

Use multimode OM3/OM4 fiber to achieve the specified 100 m reach at 25 Gbit/s, keep connectors and fiber clean, and verify that the host device firmware and port settings are configured for 25GBASE-SR operation and DOM access where required.
