CBO AOC SFP28 BlueOptics BO272703Q3M 3 m active optical cable for 25GbE ports

The CBO AOC SFP28 BlueOptics BO272703Q3M is a 3 m active optical cable designed for 25 Gigabit Ethernet links using SFP28 ports. This AOC integrates optical transceivers and a fixed duplex fiber connection in a single assembly, enabling direct connection between switches, servers and network interface cards without separate fiber transceivers. The cable supports short-reach, high-bandwidth interconnects in rack and data centre environments while providing electrical isolation and immunity to electromagnetic interference.

Advantages

This 3 m SFP28 AOC delivers low latency and consistent signal integrity for 25GbE connections. By combining transceivers and fiber in a factory-terminated cable it reduces component count and simplifies installation and inventory. The optical medium provides immunity to crosstalk and EMI found in copper solutions and reduces heat generation at device ports. Its compact SFP28 form factor preserves port density on switches and servers.

Suitable for

• High-speed server-to-switch connections within racks and adjacent racks
• Top-of-rack switch uplinks in data centres requiring 25GbE bandwidth
• Direct attach links between NICs and storage systems with SFP28 ports
• Short-reach interconnects where electrical isolation and EMI immunity are needed

Key specifications

• Form factor: SFP28 active optical cable
• Nominal data rate: 25 Gigabit Ethernet
• Length: 3 metres
• Connector type: SFP28 duplex on both ends
• Transmission medium: active optical fiber
• Typical use: short-reach, high-bandwidth links
• Latency: low, suitable for low-latency network environments
• EMI performance: immune to electromagnetic interference compared to copper

How to use

Install the BlueOptics SFP28 AOC by inserting each SFP28 connector into the corresponding SFP28 port on the network devices until the latch engages. No separate transceivers or fibre termination are required. Ensure both devices support 25GbE operation and compatible link settings, then verify link status via the device management interface. Handle the cable by the connector bodies and avoid sharp bends or tensile stress along the fiber length to maintain performance.

Recommendations

Use this AOC for short-distance, high-performance interconnects inside racks or between adjacent racks. Keep bend radius within manufacturer limits, avoid routing near high-heat components, and confirm firmware or driver compatibility on switches and NICs when deploying in heterogeneous environments.
