SFP28 transceiver CBO BO27Q856S1D 25G SR fiber optic module

The SFP28 transceiver CBO BO27Q856S1D 25G SR fiber optic module by BlueOptics is designed for short-reach 25 Gigabit Ethernet links over multimode fiber. The module uses the SFP28 form factor to provide a compact, hot-pluggable solution for data center and network switch uplinks where short-distance, high-bandwidth connections are required. It supports 25G SR optical transmission and is intended for use in environments that accept SFP28 modules, enabling straightforward installation and replacement without server or switch downtime.

Advantages

This SFP28 25G SR transceiver delivers a balance of density and performance in a small, hot-swappable module. It provides support for 25 Gigabit Ethernet over multimode fiber with low latency and power consumption suitable for aggregation and spine-leaf topologies. The compact form factor and industry-standard optical interface simplify integration into existing switch and router platforms that accept SFP28 modules.

Suitable for

• Short-reach uplinks in data centers and server racks
• Switch-to-switch connections within the same facility using multimode fiber
• Access and aggregation layer links requiring 25G bandwidth
• Environments that require hot-pluggable, high-density optical ports

Key specifications

• Optical data rate: 25 Gigabit Ethernet
• Form factor: SFP28 (hot-pluggable)
• Transmission type: Short Range (SR) over multimode fiber
• Connector type: Duplex LC-compatible optical interface
• Typical use case: Short-distance links inside data centers and wiring closets
• Power and thermal: designed for low power consumption in high-density deployments

How to use

Install the transceiver into an SFP28-compatible port on a switch or server until it clicks into place, taking care to observe the correct orientation. Connect duplex multimode fiber patch cables with LC connectors to the module’s optical interface. Ensure proper fiber type and polarity are maintained. Monitor link status via the host device to confirm successful negotiation at 25G. For removal, power down or follow hot-swap procedures recommended by your equipment vendor if required, then gently disengage the module and replace protective dust caps on the optical ports.

Recommendations

Use OM3 or OM4 multimode fiber for best performance at 25G SR distances, maintain clean fiber connectors to avoid signal degradation, and follow the host equipment’s compatibility list to ensure full functionality.
