Καλώδιο DAC BlueOptics EQPC40PC030C0100-BL QSFP InfiniBand 3m μαύρο

The BlueOptics EQPC40PC030C0100-BL QSFP InfiniBand 3m Black is a 3-meter direct attach copper (DAC) cable with QSFP connectors at both ends, engineered for high-speed InfiniBand and compatible data center interconnects. Its black outer jacket and compact form factor provide a low-latency, power-efficient physical link between servers, switches and storage systems. The cable is intended for short-reach, high-throughput environments where reliable, captive connections are required.

Advantages

This DAC cable offers low latency and predictable performance for InfiniBand applications thanks to its direct copper construction and QSFP connectors. The integrated design eliminates the need for separate transceivers, reducing component count and power consumption. A 3 m length balances reach and signal integrity for rack-to-rack and intra-rack connections, while the robust black jacket contributes to mechanical durability and straightforward cable management.

Suitable for

• Server-to-switch and switch-to-switch connections in data centers
• High-performance computing clusters using InfiniBand fabrics
• Short-reach storage connectivity and SAN interlinks
• Environments requiring low-latency, high-throughput links

Key specifications

• Cable type: Direct Attach Copper (DAC)
• Length: 3 m
• Connectors: QSFP to QSFP
• Typical use: InfiniBand and high-speed data interconnects
• Colour: Black
• Weight: approx. 0.25 kg

How to use

Install the DAC cable by firmly inserting each QSFP connector into the corresponding QSFP port on your networking equipment until the latch engages. Ensure both devices are powered down or follow hot-plug recommendations from the equipment vendor if supported. Route the cable to avoid sharp bends and maintain the recommended bend radius for copper assemblies. Verify link status through your switch or host interface; firmware or driver settings may be required to enable InfiniBand links.

Recommendations

For optimal performance, use the 3 m DAC cable for short-reach connections within racks or between adjacent racks. Avoid excessive bending or kinking, and protect connectors from contaminants. Confirm compatibility with your equipment's QSFP ports and firmware, and follow data center cable-management practices to maintain airflow and serviceability.
