CBO AOC SFP-25G-D-AOC-5M active optical cable, 25 Gbps, 5 m, SFP28 to SFP28

The CBO AOC SFP-25G-D-AOC-5M active optical cable is a factory-terminated SFP28-to-SFP28 link engineered for short-reach, high-bandwidth connections. With an aggregated data rate of 25 Gbps per lane and a fixed 5 m length, this BlueOptics AOC is intended for direct interconnects between servers, switches and storage devices in data centers and network racks. The cable uses optical signaling to reduce power consumption and latency compared with equivalent electrical direct-attach copper options, and supports plug-and-play installation in compatible 25G SFP28 ports.

Advantages

The active optical construction delivers stable 25 Gbps performance over the 5 m span while keeping weight and bulk low. Optical transmission reduces electromagnetic interference and heat generation versus copper DACs, contributing to lower system power consumption and improved thermal behaviour. Factory termination and standardized SFP28 connectors ensure compatibility with devices that support 25G SFP28 interfaces and simplify deployment without manual fiber termination or transceiver installation.

Suitable for

• Short-reach links inside racks and between adjacent racks in data centres
• High-density switch-to-switch or server-to-switch interconnects requiring 25G bandwidth
• Storage area network connections and aggregation layers with 25G SFP28 ports

Key specifications

• Connector type: SFP28 to SFP28
• Data rate: 25 Gbps per lane (aggregated 25G operation)
• Cable type: Active optical cable (AOC)
• Length: 5 metres (fixed)
• Transmission medium: Optical fiber with integrated transceivers
• Typical advantages: lower power consumption and reduced EMI compared with electrical DAC

How to use

Install the cable by inserting each SFP28 connector into the corresponding 25G SFP28 port on the two devices to be connected. Ensure both devices support 25G operation and that ports are enabled in the network equipment configuration. The cable is factory-terminated and requires no additional tooling; once seated, the devices will detect the link and negotiate speed automatically according to their firmware and port settings. Avoid bending the cable sharply at the connector and route it to prevent mechanical stress.

Recommendations

For reliable operation, use the 5 m AOC for short-reach connections inside racks or between neighbouring racks. Verify compatibility with the networking equipment vendor’s supported transceiver list when operating in mixed-vendor environments, and follow standard ESD precautions when handling SFP28 modules and ports.
