CBO QSFP Active Optical Cable S26361-F3986-L405-BL 40 Gbit/s, 5 m, Male-to-Male

Active Optical Cable CBO S26361-F3986-L405-BL with QSFP connectors delivers 40 Gbit/s data throughput over a 5 m length. This male-to-male assembly uses optical transmission inside a flexible cable jacket to provide electrical isolation and reduced electromagnetic interference compared with copper solutions. The cable is intended for short-reach interconnects in data centers, network racks and high-density server or storage environments where low latency and reliable high-speed links are required.

Advantages

The active optical design supports 40 Gbit/s links with low power consumption at each end and stable signal integrity across the full 5 m span. Optical transmission eliminates susceptibility to EMI and ground loop issues, while the plug-and-play QSFP connectors enable quick installation without additional transceivers. The cable’s compact construction simplifies routing in dense rack environments and helps maintain consistent performance under varying electrical conditions.

Suitable for

• Interconnects between servers, switches and storage in data centers
• High-density rack-to-rack short-reach links
• Connections where electrical isolation and low EMI are required
• Environments that require 40 Gbit/s throughput with minimal latency

Key specifications

• Data rate: 40 Gbit/s
• Cable type: active optical cable (AOC)
• Connector type: QSFP male-to-male
• Length: 5 m
• Transmission medium: optical fibers within active assembly
• Typical use: short-reach server, switch and storage interconnects

How to use

Ensure both link endpoints support QSFP-based 40 Gbit/s connections before installation. Power down or follow hot-swap procedures for your equipment if required by the manufacturer, then insert each QSFP plug fully into the corresponding port until the connector latch engages. Route the flexible cable to avoid sharp bends and mechanical strain; maintain the recommended minimum bend radius specified by your equipment vendor. After connection, verify link status and throughput using the host devices’ management interface or diagnostic tools.

Recommendations

Store and handle the cable to avoid kinks, tight bends and exposure to liquids or corrosive agents. Use in typical data center temperature and humidity ranges, and inspect QSFP connectors for debris before mating to prevent port contamination. For longest service life, avoid frequent unplugging cycles and follow equipment vendor guidance for hot-plug procedures.
