BlueOptics 40G-DACP-QSFP50CM-BL InfiniBand fibre optic cable 0.5 m QSFP Black

The BlueOptics 40G-DACP-QSFP50CM-BL InfiniBand fibre optic cable 0.5 m QSFP Black is a direct-attach copper-style active optical cable designed for short-reach, high-bandwidth connections in data centers and enterprise networks. With QSFP male connectors on both ends and a compact 0.5 m length, the cable provides a reliable physical link for 40 Gbps InfiniBand and other high-speed interconnect applications while minimizing signal loss and crosstalk.

Advantages

This 0.5 m QSFP cable combines the low latency and high throughput required by modern server-to-switch and switch-to-switch links. The active optical design offers stable signal integrity over short distances and reduces the thermal and electrical interference typical of passive copper alternatives. Its compact length improves cable management in dense rack environments and helps maintain airflow and accessibility around network equipment.

Suitable for

• Short-reach connections between switches and servers in data centers
• High-bandwidth InfiniBand fabrics and clustered computing environments
• Connections between network devices requiring QSFP interfaces
• Situations where compact cabling and tidy rack management are required

Key specifications

• Connector type: QSFP male to QSFP male
• Cable type: active fibre optic cable suitable for InfiniBand
• Rated data rate: 40 Gbps
• Length: 0.5 m
• Color: black
• Applications: short-reach high-speed interconnects in data centers

How to use

Plug each QSFP connector securely into the corresponding QSFP port on network switches, servers, or adapters. Ensure connectors are aligned and fully inserted until the latch engages. Verify that connected equipment recognizes the link and that interface status indicators show an active connection. Handle the cable by the connectors and avoid sharp bends along the optical fiber to preserve signal performance.

Recommendations

For optimal performance, use this 0.5 m QSFP cable for short-distance links within racks or between adjacent racks. Avoid exceeding recommended bend radius and keep the cable away from sources of strong electromagnetic interference. Confirm compatibility with device QSFP port specifications before deployment and perform link tests after installation to ensure stable operation.
