BlueOptics QSFP28-DAC-5M-MV InfiniBand/fibre optic cable 5m Male/Male

The BlueOptics QSFP28-DAC-5M-MV is a 5‑meter direct attach cable with QSFP28 connectors on both ends, designed to deliver low-latency, high-bandwidth links for InfiniBand and Ethernet networks. It supports short-reach interconnects between switches, servers and storage systems in data center environments where reliable, high-throughput connectivity is required. The cable is engineered for consistent signal integrity and reduced power consumption compared with optical transceivers, making it suitable for dense rack deployments and high-performance computing clusters.

Advantages

This QSFP28 direct attach cable provides a straightforward physical connection with minimal insertion loss and stable electrical performance across its 5‑meter length. It eliminates the need for separate transceivers and optical modules, lowering system complexity and operating costs. The male-to-male QSFP28 interface ensures compatibility with standard QSFP28 ports and supports multi-lane data transmission for high aggregate throughput. Its robust construction is intended for frequent handling and rack-level installations.

Suitable for

• Server-to-switch and switch-to-switch connections in data centers
• High-performance computing (HPC) clusters and InfiniBand fabrics
• Storage area networks and SAN interconnects
• Top-of-rack and end-of-row rack cabling where 5 m reach is required

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable length: 5 meters
• Supported protocols: InfiniBand and Ethernet short-reach links
• Performance: multi-lane high-bandwidth direct attach cable suitable for 100Gb/s class interconnects
• Physical: ruggedized assembly for rack and data center use

How to use

Install the BlueOptics QSFP28-DAC-5M-MV by inserting each QSFP28 connector into a compatible QSFP28 port on your equipment until the latch engages. Ensure both ends are securely seated and that connected devices are powered down or follow hot‑plug procedures recommended by the equipment manufacturer. Verify link status through the device management interface and confirm negotiated speeds and lane configurations. For cable routing, avoid sharp bends and maintain appropriate separation from high‑power sources to preserve signal integrity.

Recommendations

Use this 5 m QSFP28 direct attach cable for short-distance, high-bandwidth interconnects inside racks or between adjacent racks. Keep connectors clean and protected when not in use, and avoid repeated mating cycles beyond the manufacturer’s specified connector lifetime to maintain performance.
