AOC CBO AOC-SFP-25G-5M-BO Active Optical Cable SFP28 25 Gbit/s, 5 m

AOC CBO AOC-SFP-25G-5M-BO Active Optical Cable SFP28 25 Gbit/s, 5 m is a factory-terminated SFP28 direct-attach cable designed for short-reach, high-speed interconnects. The 5 m active optical link supports a 25 Gbit/s data rate and is intended for connectivity between switches, servers and network interface cards that accept SFP28 modules. Its optical construction reduces electromagnetic interference and cable weight while providing low-latency performance suitable for data centre and enterprise rack-to-rack or within-rack links.

Advantages

The active optical cable delivers consistent 25 Gbit/s throughput with lower power loss over the 5 m length compared with copper alternatives. Its small SFP28 form-factor connectors enable direct attachment to SFP28 ports without transceivers, simplifying deployment and reducing component count. The optical medium limits crosstalk and EMI, making it suitable for dense cabling environments. The cable's flexibility and lighter weight improve cable management in racks and trays.

Suitable for

• Short-reach server-to-switch and switch-to-switch connections within racks and between adjacent racks
• High-density top-of-rack networking where SFP28 ports are available
• Data centre interconnects requiring 25 Gbit/s links with low latency

Key specifications

• Connector type: SFP28 active optical connectors (both ends)
• Maximum data rate: 25 Gbit/s
• Cable length: 5 metres
• Medium: optical fibre with active transceivers integrated in the cable ends
• Typical use: short-reach direct-attach optical link for 25 G networks
• Benefits: reduced EMI, low latency, lightweight and flexible cable construction

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 port until it latches. Ensure both endpoints support 25 Gbit/s operation and that ports are enabled and configured according to your switch or NIC documentation. Avoid sharp bends and secure the cable to prevent strain on the connectors. Monitor link status indicators on connected devices to confirm successful link negotiation and proper speed. When removing, press the release mechanism and pull straight to disengage the connector without twisting.

Recommendations

For reliable operation, route the cable through appropriate cable management pathways to avoid tight bends and mechanical stress. Verify compatibility with vendor switch and NIC firmware where required; in mixed-vendor environments, test the link under expected traffic conditions. Use the 5 m length for within-rack or adjacent-rack connections to maintain optimal signal integrity and latency.
