Active Optical InfiniBand Cable CBO QSFP-AOC-20M-CP-BO — QSFP to QSFP, 20 m

BlueOptics Active Optical InfiniBand Cable CBO QSFP-AOC-20M-CP-BO is a 20-meter QSFP-to-QSFP active optical cable engineered for high-speed data interconnects in data centers and high-performance computing (HPC) environments. The cable delivers optical signal transmission between QSFP ports, offering extended reach compared with equivalent copper direct-attach cables while maintaining low latency and electrical isolation. Its design supports dense rack-to-rack and intra-rack connections where reliable high-bandwidth links are required for switches, servers and storage systems.

Advantages

This Active Optical InfiniBand cable provides optical transmission that reduces electromagnetic interference and eliminates ground loop concerns common with copper links. Its 20 m length enables flexible equipment placement and simplified cable management across racks. The QSFP-to-QSFP termination ensures compatibility with devices that accept Quad Small Form-factor Pluggable interfaces, delivering consistent high-throughput performance with lower power dissipation compared to longer copper assemblies.

Suitable for

• Interconnecting QSFP-enabled switches in data center topologies
• Linking servers and compute nodes in HPC clusters
• Connecting storage arrays to host systems requiring high-bandwidth links
• Rack-to-rack and row-to-row optical cabling where 20 m reach is needed

Key specifications

• Connector type: QSFP to QSFP optical ends
• Cable type: Active optical cable (AOC)
• Length: 20 meters
• Supported link characteristics: low latency, high bandwidth suitable for InfiniBand environments
• Electrical isolation: optical transmission provides galvanic separation between devices
• Typical deployment: data center and HPC interconnects

How to use

Install the cable by inserting each QSFP connector into compatible QSFP ports on the devices to be linked, ensuring secure latching according to the device vendor's port guidance. Check port LEDs or system management interfaces to confirm link negotiation and operational status. Avoid tight bends and excessive tension along the cable run; follow standard data center fiber handling practices to maintain optical performance. If hot-pluggable QSFP ports are supported by your hardware, the cable can be connected or disconnected while systems remain powered, following vendor guidelines.

Recommendations

For reliable performance, route the 20 m Active Optical InfiniBand cable away from sources of mechanical stress, maintain minimum bend radius specified by the vendor, and verify compatibility with your QSFP ports and firmware. Use the cable where optical isolation and extended reach are required to achieve consistent, high-bandwidth InfiniBand links.
