Καλώδιο InfiniBand/οπτικής ίνας BlueOptics 720211-B21-BO 15 m QSFP

The BlueOptics 720211-B21-BO is a 15 m InfiniBand/fibre optic cable with QSFP connectors on both ends, designed for high-throughput, low-latency connections in server rooms and data centers. This cable supports optical transmission over multimode fibre and is intended for short- to medium-reach links between switches, storage arrays and high-performance computing nodes. Its blue jacket provides visible identification in dense cabling environments while the QSFP interfaces deliver a compact, high-density connection option.

Advantages

The cable provides consistent high-speed optical performance with low insertion loss and stable signal integrity across the specified link length. Dual QSFP connectors enable direct connections between compatible transceivers or QSFP ports without additional adapters. The 15 m length balances reach and manageability for typical data center topologies, and the robust outer jacket reduces mechanical wear and simplifies routing in racks and cable trays.

Suitable for

• Inter-switch links in enterprise and colocation data centers
• Connections between servers and storage systems in SAN or HPC environments
• High-bandwidth InfiniBand fabric deployments and cluster interconnects
• Short- to medium-reach optical links within racks and between adjacent aisles

Key specifications

• Connector type: QSFP on both ends
• Length: 15 meters
• Fibre type: multimode optical fibre suitable for short- to medium-reach links
• Jacket colour: blue for easy identification
• Designed for high-speed, low-latency data transmission

How to use

Confirm that both endpoints support QSFP optical interfaces and that the transceivers or QSFP ports are compatible with multimode fibre. Route the cable carefully through racks or trays to avoid tight bends and mechanical stress; maintain the minimum bend radius recommended for multimode fibre. Insert the QSFP connectors into the corresponding ports until they latch, and verify link status through the network equipment management interface. For link changes or maintenance, power down or follow hot-swap procedures as recommended by your equipment vendor.

Recommendations

Inspect connector end-faces before installation and clean with an appropriate fibre optic cleaning tool if necessary. Avoid exceeding the cable's bend radius, keep the cable away from sources of electromagnetic interference, and store spare lengths in a manner that prevents kinking. Use cable management accessories to maintain organized pathways and ensure reliable long-term performance.
