## Long description

SFP28 BlueOptics BO27Q856S3D is a 25Gbps 850nm multimode optical transceiver designed for short-range, high-speed links in network equipment. The module uses an SFP28 form factor to provide hot-pluggable 25 Gigabit Ethernet connectivity over multimode fiber, suitable for installation in switches, routers and servers. It is intended for data center uplinks and server-to-server interconnects where compact size and reliable 25Gbps throughput are required.
Advantages
The transceiver delivers 25Gbps line rate on multimode fibre with an 850nm wavelength optimized for short-reach links. Its SFP28 form factor enables hot-pluggable insertion and removal without shutting down host equipment, while the compact design conserves port density in rack-mounted switches and servers. Compatibility with standard 25 Gigabit Ethernet interfaces ensures straightforward integration into existing network infrastructures. The module’s electrical and optical characteristics are engineered for stable, low-latency transmission in dense data center environments.
Suitable for
Data center uplink and spine connections
Server-to-server high-speed interconnects
Top-of-rack switch ports requiring 25Gbps links
Short-reach multimode fiber links within campus or enterprise racks
Key specifications
Interface type: SFP28 hot-pluggable module
Data rate: 25 Gigabits per second
Wavelength: 850 nm for multimode fibre
Fiber type: Multimode (MMF)
Typical reach: short-range multimode links (designed for intra-rack and short campus links)
Application: 25 Gigabit Ethernet
Form factor: Compact SFP28 compatible with standard cages and connectors
How to use
Install the SFP28 transceiver into an appropriate SFP28 slot on a switch, router or server while the host device is powered on to take advantage of hot-pluggable operation. Connect multimode fiber patch cords with matching LC connectors and ensure correct polarity. Verify link status through the host device’s management interface and secure fiber routing to avoid bends below the minimum bend radius. If necessary, consult the networking equipment documentation for port configuration and 25GbE settings.
Usage recommendations
Use quality multimode fiber and certified LC patch cords to achieve reliable 25Gbps performance; avoid using single-mode fiber or mismatched connectors. Confirm compatibility with the host device’s transceiver support list and perform link testing after installation to validate throughput and signal integrity.
