SFP28 transceiver module BlueOptics BO27Q856S3D-BO 25000 Mbit/s

The BlueOptics BO27Q856S3D-BO SFP28 transceiver module is designed for high-speed optical links with a maximum data transfer rate of 25,000 Mbit/s. Housed in a robust silver metal shell and weighing approximately 40 g, this compact SFP28 module supports LC duplex connections and is built to meet MSA physical and electrical standards. The module offers long operational reliability with a rated MTBF of 1,000,000 hours and is intended for multimode fiber links in data center and network environments.

Advantages

The module combines a compact SFP28 form factor with a durable metal housing and compatibility with standard LC duplex multimode patching. It supports high data throughput up to 25 Gbit/s while maintaining low weight and physical footprint. The design follows MSA specifications for optical transceivers and includes digital diagnostics monitoring (DDM/DOM) capability for real-time status of optical power, laser bias, supply voltage and temperature when supported by host hardware. Long MTBF and component selection aim to provide extended operational lifetime and reduced maintenance.

Suitable for

• 25G Ethernet aggregation and server uplinks in data centers
• High-speed inter-switch links over multimode fiber
• Storage and virtualization network connections
• Environments requiring small-form-factor pluggable optics with DDM support

Key specifications

• Interface type: SFP28 (MSA compliant)
• Maximum data transfer rate: 25,000 Mbit/s (25G)
• Connector: LC duplex (multimode operation)
• Wavelength: 850 nm (multimode)
• Typical reach: up to 300 meters over multimode fiber
• Product colour: Silver; housing: metal
• Weight: approx. 0.04 kg
• Digital diagnostics monitoring (DDM/DOM): supported when host hardware provides access

How to use

Insert the SFP28 transceiver into a compatible SFP28 slot on a switch, router or server following the host device manufacturer’s hot-plug instructions. Connect LC duplex multimode fiber patch cords to the module’s LC ports, ensuring correct transmit/receive orientation. Verify link status and, if available, read DDM/DOM values through the host system to confirm optical power, temperature and other diagnostic parameters. Follow standard ESD precautions during handling and avoid bending fibers beyond their specified minimum bend radius.

Recommendations

Use multimode OM3/OM4 fiber for best performance at 25G over the stated reach, and ensure firmware/driver compatibility with the host device. For reliable operation, keep connectors clean and perform regular inspection of fiber endfaces. Confirm that the host platform supports DDM/DOM to access real-time diagnostics for proactive maintenance.
