## Summary description

The BlueOptics FN-CABLE-QSFPDD-DAC-02-BL is a high-quality 2-meter InfiniBand/fibre optic cable featuring QSFP-DD connectors on both ends. This cable is designed for high-speed data transmission, ensuring reliable connectivity for data centers and networking applications. Its durable construction and black color make it suitable for professional environments, providing excellent performance and longevity.

## Long description

The BlueOptics FN-CABLE-QSFPDD-DAC-02-BL is a 2 m QSFP-DD direct attach cable designed for high-speed InfiniBand and 400G environments. With QSFP-DD connectors on both ends and a compact twinax construction, this black cable provides a short-range, high-throughput connection between rack-mounted devices such as switches, routers and storage systems. The passive design transmits electrical signals without onboard active circuitry and is intended for installations that support passive DAC twinax copper solutions.
Advantages
This 2 m cable delivers high data throughput with low latency and low power consumption thanks to its passive twinax construction. Its QSFP-DD to QSFP-DD connectivity follows MSA-compatible form factor guidelines to ensure mechanical fit and interoperability with hardware platforms that accept QSFP-DD passive DACs. The cable’s compact design and robust jacket make it suitable for dense rack environments while minimizing cable bulk and easing routing between adjacent racks or within a rack.
Suitable for
Interconnecting switches and routers within a rack or to neighboring racks
High-performance computing and InfiniBand clusters requiring short-range 400G links
Direct attach connections between storage arrays and host interfaces
Key specifications
Cable length: 2 m
Connector type: QSFP-DD to QSFP-DD
Transmission type: passive twinax/direct attach for short-range high-speed links
Typical use: 400G / InfiniBand short-distance interconnects
Product colour: Black
Weight: approximately 0.15 kg
How to use
Ensure both devices support passive QSFP-DD DAC connections and the intended data rate before installation. Power down or follow hot-plug guidelines of the equipment manufacturer when inserting or removing QSFP-DD modules if required. Align each QSFP-DD connector with the host port and insert until the retention mechanism engages. Route the cable to avoid sharp bends and mechanical strain; maintain minimum bend radius as recommended for twinax cables. Verify link status on connected devices and confirm negotiated speed and link health through the switch or host interface diagnostics.
Usage recommendations
Use this cable for short-distance, high-bandwidth links where passive twinax DACs are supported by the hardware. For longer distances or optical transmission, choose a supported active optical or fiber solution. Regularly inspect connectors for contamination and ensure proper cable strain relief to maintain reliable, low-latency connections.
