Network Cable BlueOptics 980-9I35S-00W01A QSFP-DD BlueLAN DAC 2m Blue

The BlueOptics 980-9I35S-00W01A QSFP-DD BlueLAN DAC 2m Blue is a direct attach copper (DAC) cable engineered for short-reach, high-density network interconnects. With a 2 meter length and QSFP-DD form factor, this blue cable supports high-speed connections between compatible QSFP-DD ports in switches, routers and servers while minimising signal loss through a passive copper construction. The cable is suitable for rack-to-rack and intra-rack connections where low latency and reliable physical link performance are required.

Advantages

This BlueOptics QSFP-DD DAC cable provides a straightforward, low-power solution for high-density networking environments. Its passive copper design offers predictable electrical performance with minimal additional configuration, while the 2 m length balances flexibility and tidy cable management. The durable jacket and keyed QSFP-DD connector ensure secure mating and consistent physical contact across frequent insertions.

Suitable for

• Rack-to-rack and intra-rack connections in data centers
• High-density switch-to-switch or switch-to-server links
• Short-reach 100G/200G/400G interconnects where QSFP-DD ports are available

Key specifications

• Form factor: QSFP-DD (double density quad small form-factor pluggable)
• Cable type: Direct Attach Copper (DAC), passive
• Length: 2 metres
• Color: Blue
• Connector: QSFP-DD compatible plug on both ends
• Typical use: Short-reach, high-density Ethernet interconnects

How to use

Install by aligning the keyed QSFP-DD plugs with the device port and inserting until the connector latches. Ensure both ends are fully seated and that connected devices are powered off or follow the vendor's hot-plug guidelines when inserting into live equipment. Route the cable to avoid sharp bends and maintain the manufacturer’s minimum bend radius. Verify link status and speed on the network devices after connection to confirm proper operation.

Usage recommendations

For best results, use this QSFP-DD DAC cable for short-distance links inside racks or between adjacent racks. Avoid excessive bending, kinking or mechanical strain, and keep connectors free of dust. Confirm compatibility with the vendor's supported transceiver and cable list before deployment to ensure link negotiation and performance.
