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

CBO InfiniBand Active Optical Cable QSFP-AOC-20M-IX-BO — QSFP+ to QSFP+, 20 m is a factory-assembled active optical link that connects QSFP+ ports over a 20 metre distance. The cable integrates optical transceivers and a fiber link in a single assembly, providing a low-latency, high-bandwidth connection for InfiniBand environments without separate SFP/QSFP modules. It is intended for use in environments that require reliable, low-jitter links between switches, servers and storage appliances, and offers longer reach and lighter weight compared with equivalent copper cables.

Advantages

The active optical construction eliminates the need for separate transceivers and reduces installation complexity while maintaining signal integrity over longer distances. Its QSFP+ to QSFP+ form factor supports standard InfiniBand port interfaces and preserves full data rates and low latency characteristics typical for direct-attach optical solutions. The factory-terminated design ensures consistent optical performance and simplifies inventory management.

Suitable for

• Data centre uplinks between switches and aggregation devices
• High-performance computing (HPC) cluster interconnects
• Storage area networks and storage fabric connections
• Server-to-switch connections where reduced weight and EMI immunity are required

Key specifications

• Connector type: QSFP+ female to QSFP+ female
• Length: 20 metres
• Media: active optical cable with integrated transceivers
• Designed protocol: InfiniBand (compatible with QSFP+ InfiniBand ports)
• Performance focus: low latency, high bandwidth links for short-to-medium reach
• Construction: factory-assembled, factory-terminated optical assembly

How to use

Install the QSFP-AOC-20M-IX-BO by inserting each QSFP+ end into compatible QSFP+ ports on the devices to be linked. Ensure ports are powered down or the host advises hot-plug support if inserting into live equipment, and verify port compatibility with QSFP+ InfiniBand signalling. Route the cable to avoid sharp bends and physical strain; secure the cable to racks or cable management fixtures if required. After connection, check link status indicators on connected devices to confirm the optical link is established and operating at the expected rate.

Recommendations

Avoid bending the cable beyond the manufacturer’s minimum bend radius and protect connector ends from contamination when not in use. Use in environments within specified temperature and humidity ranges and pair with InfiniBand-compatible hardware that supports QSFP+ optical AOCs for optimal performance.
