Active Optical Cable CBO SFP28-AOC-20M 20 m SFP28 AOC for 25GbE connections

The BlueOptics Active Optical Cable CBO SFP28-AOC-20M is a 20-metre SFP28 AOC engineered for 25GbE-compatible links. This pre-terminated cable integrates SFP28 connectors and optical transceivers into a single assembly, enabling direct optical connections between switches, servers and routers without separate pluggable transceivers. It is intended for short- to medium-range interconnects in data centres and enterprise networks where low latency, stable signal integrity and simplified deployment are priorities.

Advantages

This SFP28 AOC delivers high-bandwidth 25 Gigabit Ethernet links with optical signal transmission that reduces electromagnetic interference and crosstalk compared with copper alternatives. The integrated design removes the need to purchase and install separate transceivers, simplifying inventory and reducing potential compatibility issues. With a fixed 20 m length, the cable provides predictable optical performance and consistent latency across links in rack-to-rack, switch-to-switch and server-to-switch topologies.

Suitable for

• Rack-to-rack and intra-rack connections in data centres
• Interconnects between switches and aggregation devices
• Server uplinks and top-of-rack switch connections
• High-density network deployments requiring low-latency links

Key specifications

• Connector type: SFP28 on both ends
• Length: 20 metres
• Supported data rate: 25 Gigabit Ethernet (25GbE)
• Transmission medium: multimode optical link within AOC assembly
• Latency: low, suitable for latency-sensitive applications
• Compatibility: designed for SFP28 ports supporting 25GbE
• Cable design: pre-terminated, hot-pluggable AOC

How to use

Insert each SFP28 connector into the corresponding 25GbE-capable SFP28 slot on network devices until it latches. Ensure connected devices are powered and configured for the target link speed; most switches and servers will auto-negotiate 25GbE where supported. Route the cable to avoid sharp bends and mechanical strain on the connectors; secure the cable along rack rails or cable management arms as required. No separate transceiver installation or optical cleaning of ferrules is necessary because the cable is factory-terminated.

Recommendations

For reliable operation, avoid bending the cable below the manufacturer’s minimum bend radius, keep the integrated connectors free from dust before insertion, and verify firmware or compatibility notes on your network equipment for SFP28 AOC support. Use the 20 m length for planned rack-to-rack distances to maintain predictable link characteristics and simplify cable management in dense installations.
