Network Cable BlueOptics 980-9I54A-00H00A QSFP56 DAC 0.5m Blue

The BlueOptics 980-9I54A-00H00A QSFP56 DAC 0.5m Blue is a direct-attach copper cable engineered for short-reach, high-speed interconnects in data center and network equipment. At 0.5 meters length it provides a low-latency, low-power alternative to optical transceivers for connecting QSFP56 ports, supporting high-throughput links while maintaining signal integrity over copper. The cable housing and connectors are designed for rack and switch environments where dense cabling and reliable electrical contact are required.

Advantages

This QSFP56 DAC delivers consistent electrical performance suitable for 200Gb/s (or supported per QSFP56 standard) port implementations, with minimal insertion loss and reduced heat dissipation compared to active optical solutions. The fixed 0.5 m length minimizes excess cable slack in constrained racks and improves airflow. The robust blue jacket provides clear visual identification within complex cabling runs and the integrated connector shells ensure stable mechanical connection under standard operating conditions.

Suitable for

• Short-reach connections between switches, routers and network adapters in data centers
• Top-of-rack and spine-leaf architectures requiring high-density cabling
• Server-to-switch links where low latency and power efficiency are priorities

Key specifications

• Interface: QSFP56 direct-attach copper (DAC) form factor
• Length: 0.5 meters
• Data rate compatibility: designed for high-speed 200Gb/s class links (QSFP56)
• Cable type: twinaxial copper with molded connector housings
• Color: blue jacket for rack identification
• Connector durability: designed for repeated insertion/removal typical in rack environments

How to use

Ensure both devices support QSFP56 DAC connections and are powered off or follow hot-plug guidelines from the equipment vendor. Align the cable connectors with the QSFP56 ports and insert firmly until the latch engages. Verify link status via the switch or host interface LEDs and monitor for correct negotiated speed. For cable removal, depress the latch mechanism and pull straight out to avoid damaging the port or connector.

Usage recommendations

Install the cable in environments within the operating temperature and humidity range specified by your networking equipment. Use 0.5 m DACs for short interconnects to reduce cable congestion and maintain proper airflow; avoid sharp bends and excessive tension on the cable to preserve signal integrity and connector life.
