Active Optical Cable CBO SFP28-AOC-10M 10 m SFP28 DAC for 25GbE connections

The Active Optical Cable CBO SFP28-AOC-10M is a 10-metre plug-and-play AOC with SFP28 interfaces designed for 25GbE connectivity. It links SFP28 ports on switches, servers or network interface cards directly without separate transceivers, delivering a compact optical connection for short to medium distance data centre interconnects. The cable lowers electromagnetic interference and power consumption compared with some copper alternatives while maintaining low latency and a small form factor suitable for dense rack environments.

Advantages

This SFP28 AOC supports 25 Gigabit Ethernet data rates and offers a fully integrated, factory-terminated optical connection that removes the need to install separate transceivers. The 10 m length covers typical top-of-rack to aggregation or adjacent-rack links and helps reduce cable bulk in high-density installations. As an optical solution, it provides immunity to electromagnetic interference and typically consumes less power than active copper direct attach alternatives, contributing to lower operating costs in aggregated deployments.

Suitable for

• Top-of-rack to aggregation switch connections in data centres
• Server to switch links requiring 25GbE bandwidth
• High-density rack environments where compact cabling is needed
• Short- to medium-distance interconnects with low-latency requirements

Key specifications

• Interface type: SFP28 to SFP28 optical assembly
• Rated data rate: 25 Gigabit Ethernet
• Cable type: active optical cable (AOC)
• Length: 10 metres
• Form factor: hot-pluggable SFP28 modules integrated in cable ends
• EMI behaviour: immune to electromagnetic interference typical of fibre optics
• Power: low-power design compared with many active copper alternatives

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on network switches, servers or NICs until the latch engages. No separate transceivers or external configuration are required for basic link operation; devices should auto-negotiate the 25GbE link if the hardware and firmware support that speed. Ensure both ends are seated properly and that cable bend radius and rack routing follow standard fibre handling practices to avoid damage.

Recommendations

For reliable performance, maintain recommended minimum bend radius, avoid tight cable ties and route the AOC away from crush points. Verify switch or NIC compatibility with SFP28 AOCs and ensure firmware is up to date if vendor-specific link validation is required. Use the 10 m length for rack-to-rack or top-of-rack aggregation links; for longer runs select an appropriate optical transceiver and fibre patching solution.
