Direct Attach Cable BlueOptics 9613CM100CAB2-0030 QSFP28 100GBASE-CR4 Infiniband EDR 26AWG 3m

The BlueOptics Direct Attach Cable 9613CM100CAB2-0030 is a QSFP28 100GBASE-CR4 copper assembly designed for short-reach high-bandwidth interconnects. With a 3 meter length and 26AWG conductors, this DAC supports 100 Gigabit Ethernet links and Infiniband EDR environments. The cable uses QSFP28 connectors on both ends and is intended for direct attachment between servers, switches and storage devices where low latency and high throughput are required.

Advantages

This QSFP28 direct attach copper cable delivers a cost-effective, low-power alternative to optical transceivers for short 100G links. Its 26AWG construction provides reliable signal integrity for 100GBASE-CR4 and Infiniband EDR, while the standardized QSFP28 form factor ensures compatibility with equipment designed for QSFP28 ports. The fixed 3 m length reduces excess cabling in dense racks and helps maintain predictable electrical performance across short distances.

Suitable for

• Short-reach 100 Gigabit Ethernet connections between switches and top-of-rack servers
• High-throughput Infiniband EDR links in compute clusters
• Direct server-to-storage or switch-to-storage interconnects in data centers
• Racks and cabinets where low latency and low power consumption are priorities

When it may not be suitable

This direct attach copper cable is optimized for short-reach links and is not appropriate for longer-distance connections that require fiber optics. Environments that call for hot-pluggable optical transceivers, longer link budgets, or where electrical routing through patch panels is required may be better served by fiber optic solutions or active optical cables.

Key specifications

• Connector type: QSFP28 on both ends
• Data rate: 100 Gbps (100GBASE-CR4)
• Supported protocol: Infiniband EDR compatible
• Cable gauge: 26 AWG
• Length: 3 m
• Cable type: Direct attach copper (DAC)

How to use

Install the BlueOptics QSFP28 DAC by inserting each QSFP28 connector into the corresponding 100G QSFP28 port on your network equipment until the latch engages. Verify link status and configuration in the host devices or switch management interface. The cable is ready to use without additional optics configuration; ensure both endpoints support 100GBASE-CR4 or Infiniband EDR for proper operation. Handle the cable by the connector housings to avoid bending the conductors and maintain the recommended bend radius for copper assemblies.

What to consider before purchase

• Confirm that both devices have QSFP28 ports and support 100GBASE-CR4 or Infiniband EDR
• Verify that a 3 m fixed-length DAC fits your rack layout and does not require additional cable management
• Ensure your equipment vendor allows passive DACs or comparable copper cables for warranty and compatibility considerations

Usage recommendations

Use the 3 m BlueOptics QSFP28 DAC for direct short links within racks or between adjacent racks where low latency and low power are priorities. Avoid tight bends, excessive strain, and routing near high-power sources to maintain performance and longevity.
