Active Optical Cable (AOC) CBO SFP28-AOC-5M 5 m — SFP28 25Gbps direct-attach optical cable

CBO SFP28-AOC-5M is a 5-meter active optical cable (AOC) equipped with SFP28 connectors and engineered for 25 Gbps links. The cable integrates optical transceivers inside the assembly to provide a compact, hot-pluggable direct-attach solution that replaces passive copper DACs for short-reach connections. It is intended for server-to-switch, switch-to-switch and uplink applications in data centers and enterprise networks where stable 25GbE connectivity and reduced electromagnetic interference are required.

Advantages

The Active Optical Cable offers native SFP28 compatibility with 25Gbps signaling while maintaining a slim, lightweight form factor. By incorporating optical transceivers into the cable, it minimizes crosstalk and electromagnetic interference compared with copper alternatives and enables reliable signal integrity over the 5 m link. The AOC design supports hot-pluggable deployment and eliminates the need for separate transceiver modules, simplifying inventory and installation in dense rack environments.

Suitable for

• Server-to-switch connections in data centers
• Switch-to-switch links for aggregation and spine-leaf topologies
• High-speed uplinks between switches or routers
• Short-reach 25GbE links where reduced EMI is required

Key specifications

• Connector type: SFP28 to SFP28 compatible
• Nominal length: 5 meters
• Data rate: 25 Gbps per channel (25GbE)
• Cable type: Active optical cable with integrated transceivers
• Signal medium: Optical fiber within AOC assembly
• Form factor: Direct-attach, hot-pluggable
• Typical use: Short-reach links in rack and spine-leaf deployments

How to use

Install the AOC by inserting each SFP28 connector into the corresponding SFP28 port on your network devices until the latch engages. Ensure both ends are fully seated and that the connected devices are compatible with SFP28 AOC modules. Configure the network interfaces on the connected devices according to your switch or server operating system requirements, and verify link status through device management or CLI tools. No separate transceiver installation is required because the optical transceivers are integrated in the cable assembly.

Usage recommendations

Handle the cable by the connector housings and avoid sharp bends or excessive pulling; follow minimum bend radius guidelines to prevent signal degradation. Use in clean rack environments and ensure ports and connectors are free from dust before insertion. For interoperability, verify device compatibility with SFP28 active optical cables and update device firmware if required for optimal link negotiation.
