SFP28 25G SR Fiber Optic Transceiver, CBO SFP28-25G-SR 25Gbps short-range

The BlueOptics CBO SFP28-25G-SR is a 25G SFP28 short-range (SR) fiber optic transceiver designed for high-speed data links over multimode fiber. It enables 25 Gigabit Ethernet connections for short-distance links commonly found in modern data centers, server interconnects, aggregation and access layers. The module uses the SFP28 hot-pluggable form factor for straightforward installation and replacement without powering down network equipment.

Advantages

This 25Gbps transceiver offers a compact SFP28 footprint that simplifies port upgrades from lower speeds while conserving rack space. The SR optics are optimized for short-distance multimode fiber runs, delivering reliable high-bandwidth connectivity with low latency. Hot-pluggability and standardized electrical and optical interfaces make the module compatible with a wide range of switches and servers that support SFP28 modules, reducing maintenance time and enabling rapid hardware refresh.

Suitable for

• Short-range 25 Gigabit Ethernet links within data centers
• Server-to-switch and switch-to-switch interconnects in aggregation and access layers
• High-density network deployments requiring compact transceivers
• Upgrading existing SFP/SFP+ ports to 25Gbps capable links

Key specifications

• Data rate: 25.78 Gbps (25G Ethernet)
• Form factor: SFP28, hot-pluggable
• Optical interface: Short-range (SR) for multimode fiber
• Supported medium: Multimode fiber (MMF)
• Typical reach: designed for short-distance links within data centers
• Low power consumption suitable for high-density ports

How to use

Insert the SFP28 module into a compatible SFP28 slot on a switch, router or server until it clicks into place. Connect the multimode fiber patch cable to the transceiver's optical port, ensuring correct polarity and that the connector types match. The module is hot-pluggable, so it can be installed or replaced while the host device remains powered, but follow your equipment vendor's guidelines for handling optical transceivers and static-sensitive components. Verify link status and speed through device management interfaces after installation.

Recommendations

Use high-quality multimode fiber and appropriate patch cords (LC connectors where applicable) to achieve expected short-range performance. Observe manufacturer guidelines for operating temperature, dust protection for optical ports, and ESD precautions during handling. For interoperability, confirm that the host device supports SFP28 25G SR modules and update firmware if required.
