BlueOptics QSFP-40G-CU3M cavo in fibra ottica InfiniBand 3 m nero

The BlueOptics QSFP-40G-CU3M InfiniBand/fibre optic cable 3 m Black is a 3-metre twin-connector cable with QSFP terminations designed for short-distance, high-throughput connections in data centers and high-performance computing environments. This male-to-male cable supports high-speed data transmission between switches, servers, storage arrays and other network equipment that accept QSFP interfaces. The compact cable construction and black outer jacket make it suitable for dense cabling runs where space management and signal integrity are important.

Advantages

The cable provides reliable, low-latency connectivity with a design optimized for QSFP-compatible ports. Its 3 m length balances reach and signal quality for typical rack-to-rack or within-rack connections. The male/male QSFP connectors ensure straightforward plug-and-play installation with compatible devices. A robust outer jacket offers mechanical protection while maintaining flexibility for routing in constrained spaces.

Suitable for

• Interconnects between QSFP-equipped switches and routers in data centers
• Connections between servers and storage in high-performance computing clusters
• Short-reach links for InfiniBand fabrics and high-speed Ethernet links
• Patch and trunk cabling inside racks where QSFP ports are used

Key specifications

• Connector type: QSFP male to QSFP male
• Cable length: 3 metres
• Cable color: Black
• Application: InfiniBand and high-speed fibre optic links
• Use case: Short-reach, high-throughput interconnects

How to use

Identify QSFP ports on your networking equipment and ensure both ends are free of dust and debris before connection. Align each QSFP connector with the corresponding port and insert until the connector latches or seats securely. Avoid excessive bending or twisting of the cable near the connector ends to preserve signal performance. For removal, release the latch mechanism and pull the connector straight out without tilting to prevent port damage.

Recommendations

Use the cable for short-reach interconnects within racks or between adjacent racks; keep bend radius within manufacturer guidelines and avoid routing near high-interference power cables. Store unused cables coiled loosely and protect connector ends with dust caps when not in use to maintain optical and mechanical integrity.
