Direct Attach Cable BlueOptics 980-9I620-00E00A-BL, Infiniband EDR 100Gb/s, 30AWG, 0.5 m

BlueOptics 980-9I620-00E00A-BL direct attach cable is a 0.5 m passive copper link engineered for 100Gb/s Infiniband EDR environments. With 30AWG conductors and a compact, low-profile design, the cable delivers short-reach connectivity between switches, servers and storage systems in data centers and high-performance computing clusters. It is intended for rack and cabinet interconnects where a low-latency, high-throughput fabric is required.

Advantages

The cable provides native 100Gb/s bandwidth for Infiniband EDR fabrics while maintaining low insertion loss across a short distance. The 30AWG construction offers a balance between flexibility and electrical performance, enabling reliable connections in dense rack deployments. The passive design reduces power consumption and complexity compared with active optical alternatives, and the short 0.5 m length minimises signal degradation and cabling clutter in constrained environments.

Suitable for

• Short-reach connections between switches and servers in data center racks
• Interconnects within high-performance computing (HPC) clusters
• Storage array to host links requiring 100Gb/s Infiniband EDR throughput
• Patch cabling inside server cabinets and top-of-rack configurations

Key specifications

• Protocol compatibility: Infiniband EDR, 100Gb/s
• Cable type: Passive direct attach copper
• Conductor size: 30AWG
• Length: 0.5 m
• Typical use: Short-reach, low-latency interconnects
• Connector style: Direct attach interface for compatible InfiniBand ports

How to use

Insert the cable ends firmly into the corresponding Infiniband EDR ports on the devices to be connected, ensuring connectors are aligned and latched where applicable. Use the 0.5 m length to route the cable within a rack or between adjacent racks to minimise excess slack. Verify link status on connected devices and confirm 100Gb/s link rate in the host or switch management interface. For installation, handle the cable by its connector body and avoid tight bends that could stress the conductors.

Usage recommendations

Use the direct attach cable for short-distance, high-throughput links inside racks or between adjacent cabinets. Avoid running this passive copper cable over long distances or in environments where optical transceivers are required. Maintain bend radii recommended for 30AWG assemblies and keep the cable away from sources of electromagnetic interference for optimal signal integrity.
