InfiniBand Active Optical Cable CBO QSFP-AOC-10M-NK-BO 10 m QSFP+ to QSFP+

InfiniBand Active Optical Cable CBO QSFP-AOC-10M-NK-BO 10 m QSFP+ to QSFP+ is a 10-metre QSFP+ to QSFP+ active optical cable engineered for high-speed InfiniBand interconnects. As an AOC, it converts electrical signals to optical transmission within the cable assembly to deliver high bandwidth and low latency over a mid-range distance. The cable is intended for data center and high-performance computing environments where reliable, compact links between servers, switches and storage systems are required and where electrical copper cabling is impractical due to signal integrity or electromagnetic interference concerns.

Advantages

The active optical construction ensures stable high-throughput links with reduced signal loss compared to passive copper for the same distance. At 10 metres, the cable offers flexibility for rack-to-rack or intra-rack connections while keeping cabling density low. Optical transmission reduces susceptibility to electromagnetic interference and improves thermal behavior in dense equipment racks. The QSFP+ to QSFP+ form factor supports commonly deployed InfiniBand and Ethernet QSFP+ ports, simplifying upgrade and replacement tasks without requiring transceivers in the host devices.

Suitable for

• Rack-to-rack server interconnects in data centres
• Switch-to-switch connections in aggregation or spine-leaf topologies
• Server-to-storage links in SAN and HPC installations
• Short- to mid-range InfiniBand links where low latency is required

Key specifications

• Cable type: Active Optical Cable (AOC)
• Connector type: QSFP+ to QSFP+
• Length: 10 metres
• Target application: InfiniBand high-speed interconnects (also compatible with QSFP+ ports for Ethernet)
• Performance characteristics: low latency, high bandwidth suitable for HPC and data centre traffic
• Interference immunity: optical transmission reduces electromagnetic susceptibility

How to use

Install the cable by connecting each QSFP+ plug to compatible QSFP+ ports on the devices to be linked. Ensure both ends are fully inserted and the retention latches are engaged. No external transceivers are required as the cable integrates optical modules. Verify link status indicators on the connected devices to confirm successful negotiation. For best results, avoid sharp bends and protect the cable from compressive forces; route through standard cable management openings and maintain minimum bend radius according to manufacturer guidance.

Recommendations

Use the cable in controlled data centre environments and avoid exposure to direct sunlight, liquids or excessive mechanical stress. When replacing or re-routing cables, power down ports if operational procedures require it, and inspect connector endfaces for contamination before mating. For mixed vendor environments, confirm QSFP+ port compatibility and firmware support for active optical cables.
