Direct Attach QSFP Cable BlueOptics 980-9I67A-00L003, 56G Infiniband FDR, 28AWG, 3 m

BlueOptics 980-9I67A-00L003 is a 3 m Direct Attach QSFP passive copper cable engineered for 56G InfiniBand FDR links. The cable uses 28AWG conductors and a QSFP form-factor to deliver a compact, low-latency electrical connection between QSFP ports on switches, routers and host bus adapters. Designed for short-reach interconnects, this direct attach cable provides an economical and straightforward solution for server-to-switch and switch-to-switch links in data center and high-performance computing environments.

Advantages

The direct attach construction eliminates the need for optical transceivers and reduces component count while maintaining signal integrity for 56G InfiniBand FDR networks. With 28AWG conductors and a passive design, the cable minimizes latency and power consumption compared with active solutions. The 3 m length offers flexibility for rack-level and adjacent-rack connections, and the QSFP connector form factor ensures compatibility with standard QSFP ports used in networking equipment.

Suitable for

• Short-reach server-to-switch connections in data centers
• Switch-to-switch aggregation within a rack or between adjacent racks
• High-performance computing clusters requiring low-latency InfiniBand FDR links
• Connections to routers and host bus adapters with QSFP ports

Key specifications

• Interface: QSFP (Quad Small Form-factor Pluggable) connector on both ends
• Data rate: 56 Gbps per link (InfiniBand FDR)
• Cable type: Passive copper direct attach
• Conductor size: 28 AWG
• Length: 3 meters
• Typical use: Short-reach interconnects and rack-level cabling

How to use

Install the cable by inserting each QSFP connector into compatible QSFP ports on your networking devices until the connector latches. Ensure that ports are powered down or that hot-swap procedures recommended by the equipment vendor are followed if inserting while systems are live. Verify link status in your switch or HBA management interface and confirm negotiated speed and link health. For best performance, avoid sharp bends and compressive stress on the cable and connectors.

Usage recommendations

Use this passive 3 m QSFP direct attach cable for short-distance connections where 56G InfiniBand FDR performance and low latency are required. Avoid running the cable in environments with sources of strong electromagnetic interference and follow equipment vendor guidelines for hot-plugging. Replace the cable if the connector latching mechanism is damaged or if signal errors are observed during link diagnostics.
