Direct Attach Cable BlueOptics 980-9I62V-00C003 100Gb/s Infiniband EDR 26AWG 3m

BlueOptics 980-9I62V-00C003 is a copper Direct Attach Cable (DAC) designed for 100Gb/s Infiniband EDR links. With 26 AWG conductors and a 3 m length, this cable provides a short-reach, low-latency physical interconnect for switches, servers and storage nodes in high-performance computing and data center environments. The assembly integrates fixed connectors and a shielded twinax structure to maintain signal integrity at EDR speeds while simplifying rack-level cabling.

Advantages

The cable delivers native 100Gb/s throughput with reduced latency compared to optical transceivers over similar distances, and its copper twinax construction offers robust electromagnetic shielding and consistent performance in dense rack deployments. A 3 m length balances reach and manageability for typical top-of-rack and mid-plane connections, while the standardized EDR-compatible interface ensures interoperability with compliant networking equipment.

Suitable for

• Top-of-rack and intra-rack connections between switches and servers
• Interconnects in HPC clusters using Infiniband EDR
• Short-reach links for storage arrays and compute nodes
• Data center layouts requiring low-latency 100Gb/s cabling

Key specifications

• Data rate: 100 Gb/s
• Protocol compatibility: Infiniband EDR
• Conductor gauge: 26 AWG
• Length: 3 meters
• Cable type: Copper direct attach / twinax
• Connector type: Fixed DAC connectors for EDR systems
• Characteristic: Shielded for reduced EMI

How to use

Install the cable by firmly inserting each connector into the corresponding EDR-compatible port on your switch, server or storage device until it latches. Route the cable to avoid sharp bends and mechanical strain, maintaining the specified minimum bend radius to preserve signal integrity. For best performance, use this DAC for short-reach links within the same rack or adjacent racks and ensure connected equipment supports Infiniband EDR speeds.

Usage recommendations

Verify port compatibility and firmware support on networking equipment before deployment. Avoid prolonged exposure to temperatures or conditions outside the equipment specifications, and periodically inspect connectors and cable shielding for physical damage. Use appropriate cable management to prevent stress on connectors and to maintain airflow in the rack.
