Aktívny optický kábel CBO SFP28-AOC-7M 7 m SFP28

Active Optical Cable CBO SFP28-AOC-7M 7 m SFP28 is a 7-meter SFP28-compatible fiber link from BlueOptics designed for 25GbE direct connections between SFP28 ports. The cable integrates optical transceivers in its ends, providing a low-latency optical connection without the need for separate modules. It is intended for short-to-medium reach links inside racks and between adjacent racks, offering stable signal transmission with reduced power consumption compared with discrete transceiver-plus-copper-cable solutions.

Advantages

The Active Optical Cable delivers high-bandwidth 25Gbps throughput with consistent optical performance over a 7 m length. Its integrated design simplifies installation by eliminating the need to install separate transceivers and patch cords, which reduces setup time and potential mismatch errors. The optical link provides electrical isolation and lower electromagnetic interference compared with copper alternatives, and the AOC construction typically results in lower port power draw and compact cable routing in dense server and switch environments.

Suitable for

• 25GbE server-to-switch connections in data centers
• Inter-rack links between adjacent or nearby racks
• High-density switch-to-switch uplinks
• Short-range optical interconnects inside network cabinets

Key specifications

• Cable type: Active Optical Cable (AOC) with SFP28 interfaces
• Nominal data rate: 25 Gbps per lane (SFP28 standard)
• Length: 7 meters
• Connector form factor: SFP28 on both ends for direct port insertion
• Typical application: Short-reach 25GbE links within racks and between adjacent racks
• Latency: low, suitable for latency-sensitive server and storage connections
• EMI behaviour: optically isolated, reduced electromagnetic interference compared with copper cables

How to use

Install the Active Optical Cable by inserting each SFP28 connector into the corresponding SFP28 port on the network devices until the latch engages. Ensure ports are powered down or follow hot-swap guidelines provided by the equipment manufacturer if inserting while live. After insertion, verify link status in the host device management interface and confirm negotiated speed is 25GbE. Route the cable to avoid sharp bends and secure it in the rack to prevent stress on the connector ends. No separate transceivers or fiber patch cords are required.

Recommendations

Use the 7 m Active Optical Cable for direct short-distance 25GbE connections where a compact, low-latency optical link is required. Avoid bending the cable beyond the manufacturer’s minimum bend radius, keep connectors clean, and follow equipment vendor guidance for SFP28 port handling and firmware compatibility to ensure reliable operation.
