CBO Transceiver SFP28-25G-SR 25Gbps SR Fiber Optic Module

The CBO Transceiver SFP28-25G-SR 25Gbps SR Fiber Optic Module is a short-reach SFP28 transceiver designed to provide 25 gigabit per second connectivity over multimode fiber. Engineered for data center and enterprise networking, this hot-pluggable module fits SFP28 ports on switches, routers and servers to deliver low-latency uplinks and aggregation links. The module supports short-distance connectivity typical for server-to-switch and switch-to-switch connections within racks and across adjacent racks in campus and data center environments.

Advantages

This SFP28 SR module offers 25Gbps bandwidth in a compact SFP28 form factor, enabling higher port density without a larger physical footprint. Hot-pluggable design allows insertion and removal without powering down the host device, reducing maintenance windows. Optimized for multimode fiber, the transceiver delivers reliable performance for short-range links with low latency and consistent signal quality. The module is compatible with common networking equipment that accepts SFP28 transceivers and is suitable for high-throughput aggregation and access layers.

Suitable for

• Short-reach 25GbE server uplinks in data centers
• Switch-to-switch aggregation within racks or between adjacent racks
• High-density 25Gbps ports on enterprise switches and routers
• Low-latency connections for virtualized and storage networks

Key specifications

• Form factor: SFP28 hot-pluggable transceiver
• Data rate: 25 Gbps
• Optical reach: short-reach over multimode fiber (designed for short distances)
• Fiber type: multimode fiber (MMF)
• Application: 25 Gigabit Ethernet (25GbE) links for uplinks and aggregation
• Latency: optimized for low-latency operation

How to use

Install the module into any compatible SFP28 port on a switch, router or server until it latches securely. Connect appropriate multimode fiber patch cords to the module’s duplex optical interface, ensuring correct transmit/receive orientation. After insertion and fiber connection, the host device should automatically detect the transceiver and negotiate the link at 25Gbps. Monitor link status LEDs and device diagnostics to confirm operational parameters and link integrity.

Recommendations

Use high-quality OM3 or OM4 multimode fiber for optimal reach and performance, keep fiber connectors clean to avoid signal loss, and follow ESD precautions when handling the transceiver. For best results, verify compatibility with host equipment and ensure firmware or driver updates are applied where required.
