Network Cable BlueOptics FN-CABLE-QSFPDD-2QSFP56-L2 QSFP-DD 2xQSFP56 2m Blue

The BlueOptics FN-CABLE-QSFPDD-2QSFP56-L2 QSFP-DD 2xQSFP56 2m Blue is a high-performance direct-attach cable designed for short-reach, high-bandwidth interconnects. It provides a QSFP-DD plug to dual QSFP56 breakout, enabling conversion from a single 8-lane interface to two 4-lane interfaces over a 2-meter copper link. The cable is intended for use in dense networking environments where reliable, low-latency connections are required between switches, routers and high-speed servers.

Advantages

This 2‑meter cable supports high data throughput and low latency suitable for 200G or aggregated 100G deployments when used with compatible QSFP-DD and QSFP56 ports. The construction combines flexibility with mechanical durability for straightforward routing in rack and cabinet installations. The integrated breakout design eliminates the need for separate adapters, reducing points of failure and simplifying cabling topology. Its blue jacket provides visual identification for organized patching.

Suitable for

• High-density data center switch-to-switch connections
• Server to top-of-rack or leaf switch links
• Aggregation and uplink scenarios requiring QSFP-DD to QSFP56 breakout
• Short-reach cabling inside racks and network cabinets

Key specifications

• Connector type: QSFP-DD (single end) to 2 × QSFP56 (breakout)
• Cable length: 2 meters
• Media type: copper direct-attach cable
• Bandwidth capability: supports multi-lane high-speed links (QSFP-DD/QSFP56 class)
• Jacket color: blue
• Application environment: short-reach, intra-rack and inter-rack networking

How to use

Install the QSFP-DD end into the host port and insert the two QSFP56 ends into the target ports, ensuring secure seating until the latches engage. Route the cable to avoid tight bends and maintain the manufacturer’s minimum bend radius. Use the 2 m length to bridge adjacent equipment in the same rack or neighboring racks; avoid stretching or twisting the cable during installation. Verify link status using the connected devices' indicators and perform any required port configuration on network equipment to enable the expected aggregated or breakout operation.

Usage recommendations

For reliable operation, confirm port compatibility and firmware support for QSFP-DD to QSFP56 breakout modes on your switches or servers. Keep the cable free from sharp edges, and maintain proper airflow in racks. Replace the cable if the connector latches or the jacket show visible damage. For distances beyond short-reach copper limits, consider optical transceivers and fiber cabling.
