Ricetrasmettitore SFP28 BlueOptics BO27O856S1D (4TC7A88638-BO) – LC-Duplex, 10G/25GBASE-SR, multimodale 850 nm, 100 m, DDM, 0–70 °C

The BlueOptics BO27O856S1D SFP28 transceiver is a compact optical module designed for short-range 10G and 25GBASE-SR links over multimode fiber. It uses an 850 nm VCSEL light source and LC-duplex connectors to deliver reliable transmission up to 100 meters on suitable multimode cabling. The module supports Digital Diagnostics Monitoring (DDM) for real-time monitoring of optical parameters and is rated for operation across an industrial temperature range of 0 to 70°C.

Advantages

This SFP28 transceiver provides compatibility with both 10G and 25GBASE-SR standards, enabling flexible deployment in modern high-speed networks. Its LC-duplex interface and multimode operation simplify integration into existing data center and campus fiber infrastructures. Built-in DDM allows monitoring of temperature, optical power and other key metrics to assist with link management and troubleshooting. The compact SFP28 form factor saves port space and supports high-density switch and server interconnects.

How to use

Insert the transceiver into an SFP28-compatible port on a switch, server NIC or media converter following the host device manufacturer’s instructions. Connect LC-duplex multimode fiber patch cords, observing correct transmit/receive orientation. Verify link status on the host device and use the DDM interface to check optical power, temperature and other diagnostics through supported management tools. Ensure the fiber type and distance do not exceed the specified 100 meter reach for reliable performance.

Recommendations

For optimal results, use OM3 or OM4 multimode fiber and high-quality LC duplex patch cords. Confirm host equipment supports SFP28 modules and the required 10G/25GBASE-SR operation. Monitor DDM values after installation to identify potential issues with connectors, patch cords or bend losses, and maintain a clean fiber end-face to prevent signal degradation.
