CBO InfiniBand cable SC252501K0.5M30-BL QSFP to QSFP 0.5 m, black

The CBO InfiniBand cable SC252501K0.5M30-BL QSFP to QSFP 0.5 m is a short, black QSFP-to-QSFP interconnect engineered for high-speed InfiniBand environments. It provides a direct electrical/optical link between QSFP ports, minimising latency and maximising throughput for dense rack and chassis configurations. Its half-metre length and compact construction are intended for close-proximity connections inside server racks, switch panels and high-performance computing setups where space and signal integrity are critical.

Advantages

This QSFP-to-QSFP cable supports low-latency, high-bandwidth links suitable for InfiniBand topologies. The short length reduces signal attenuation and crosstalk compared with longer assemblies, helping to maintain link stability and performance. Its robust connectors and compact cable jacket are designed for reliable repeated insertions and tidy cable management in stacked equipment. The black jacket provides a neutral appearance that blends into typical rack environments.

Suitable for

• Direct high-speed links between QSFP ports in switches and routers
• Short-reach connections within server racks and chassis
• High-performance computing (HPC) clusters and node interconnects
• Low-latency fabrics in data centre top-of-rack or midplane installations

Key specifications

• Connector type: QSFP to QSFP
• Cable length: 0.5 m
• Colour: black
• Intended network type: InfiniBand high-speed interconnects
• Design: short, direct link for low latency and high throughput

How to use

Power down or follow hot-swap procedures recommended by your equipment vendor before making connections if required. Align each QSFP connector with the corresponding port and insert firmly until the connector latches. Route the cable to avoid sharp bends and mechanical stress, maintaining the specified minimum bend radius for QSFP assemblies. Verify link status through your switch or host interface and check that negotiated link speeds and lanes match the expected configuration.

Usage recommendations

Use this short QSFP-to-QSFP cable for intra-rack or intra-chassis interconnects where minimal cable length improves signal quality. Avoid excessive bending or tensile strain, and store or route the cable within rack cable management channels to prevent connector stress. For multi-hop or longer-distance requirements, select appropriately rated longer assemblies or active optical solutions.
