Direct Attach Cable BlueOptics 9613CM100CAB0-0030 100GBASE-CR4 Infiniband EDR 30AWG 1m

BlueOptics 9613CM100CAB0-0030 is a 1 metre Direct Attach Copper (DAC) cable engineered for 100GBASE-CR4 and Infiniband EDR environments. With 30 AWG conductors and a short, fixed-length design, this DAC provides a low-latency, high-bandwidth connection for data centre interconnects between switches, network interface cards and storage systems that support CR4 and EDR link technologies.

Advantages

The cable offers a cost-effective, power-efficient alternative to optical transceivers for short-reach links, reducing equipment and operational expenses while preserving full 100 Gbps throughput. Its factory-terminated, single-cable design eliminates the need for separate transceivers and patch cords, simplifying installation and reducing points of failure. The 30 AWG conductors and robust shielding deliver signal integrity over the 1 m span suitable for rack-to-rack or within-rack connections.

Suitable for

• High-speed 100 Gbps interconnects between switches or routers
• Direct connections from NICs to switches in data centre servers
• Storage arrays and appliances requiring CR4-compatible links
• Short-reach Infiniband EDR links within racks or adjacent racks

When it may not be suitable

This DAC is designed for short-reach links and is not appropriate for long-haul or campus backbone connections where optical transceivers and fibre are required. It also requires devices with compatible CR4/EDR electrical interfaces; it will not function with equipment that accepts only optical modules or incompatible connector types.

Key specifications

• Data rate: 100 Gbps (CR4 / EDR)
• Length: 1 metre
• Conductor gauge: 30 AWG
• Cable type: Direct Attach Copper (DAC), factory-terminated
• Suitable link types: 100GBASE-CR4, Infiniband EDR
• Typical applications: within-rack and short rack-to-rack connections

How to use

Power off or follow hot-plug instructions for your hardware, then insert each connector into the corresponding port on the two devices ensuring proper orientation. The cable is factory-terminated so no field termination is required. After connection, verify link status LEDs or software interface indicators on both devices to confirm a 100 Gbps CR4/EDR link. For cable removal, press any retention latch and withdraw straight out to avoid damaging the connector or port.

What to consider before purchase

• Confirm both devices support 100GBASE-CR4 or Infiniband EDR electrical interfaces
• Verify that a 1 m cable length matches your rack or equipment spacing
• Ensure port compatibility in terms of connector type and retention mechanism
• Assess whether copper DAC is preferred over optical solutions for your use case

Usage recommendations

Use this DAC for short, high-bandwidth connections inside racks or between adjacent racks where low latency, low power draw and cost-effectiveness are priorities. Avoid tight bends and mechanical strain on the cable and keep connectors free of dust and debris to maintain signal integrity.
