## Summary description

The BlueOptics BO27Q856S1D-BO is an SFP28 transceiver module designed for high-speed data transfer at 25000 Mbit/s. It operates at a wavelength of 850 nm and is compatible with CE and FC products. With a weight of 40 g, it is lightweight and easy to install. This module is compliant with RoHS standards, ensuring environmental safety.

## Long description

The BlueOptics BO27Q856S1D-BO is an SFP28 transceiver module for 25 Gbit/s optical links. It operates at an 850 nm wavelength over multimode fiber and supports LC duplex connections. The module complies with RoHS and relevant industrial standards and is designed to be compact and lightweight for straightforward installation in compatible SFP28 ports.
Advantages
This SFP28 transceiver offers support for 25GBASE-SR optical transmission over multimode fiber up to typical short-reach distances. Its SFP28 interface and LC duplex connector follow MSA conventions for electrical and mechanical interoperability with switches, routers and storage systems that accept compatible 25G SR modules. Built-in digital diagnostics (DDM/DOM) allow remote monitoring of supply voltage, laser bias current, optical output and input power, and temperature for basic link health checks. The module is RoHS-compliant and lightweight, simplifying handling and deployment.
Suitable for
25 Gbit/s Ethernet connections in data center aggregation and top-of-rack switches
High-speed server-to-switch links over multimode fiber
Short-reach storage and backup interconnects within racks or between adjacent racks
Environments requiring digital diagnostics for link monitoring

How to use
Insert the SFP28 transceiver into a compatible SFP28 port on the network device following the device manufacturer’s hot‑plugging guidance. Connect an LC duplex multimode fiber patch cable with the correct fiber type and polarity. Ensure the host device firmware and software support compatible 25G SR modules and, if required, enable DDM/DOM monitoring in the management interface to read diagnostic parameters. Verify link status and data rate in the device operating system or network management tool after installation.
Usage recommendations
Use multimode fiber and OM3/OM4 patch cords for optimal reach and performance. Confirm compatibility with the target hardware platform and, when possible, test a sample module in the live environment before large-scale deployment. Keep connectors clean and store unused modules in protective caps to avoid contamination and signal loss.
