## Summary description

The BlueOptics BO27Q856S3D-BO is an SFP28 transceiver module designed for high-speed data transfer up to 25000 Mbit/s. It features a robust metal housing and a long MTBF of 1000000 hours, ensuring reliability and durability. Weighing only 40 g, it is lightweight yet efficient for network applications.

## Long description

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.
Usage 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.
