InfiniBand/fibre optic cable Cisco QSFP-100G-CU2M= 2 m Black

Cisco QSFP-100G-CU2M= is a 2-meter copper direct-attach cable with QSFP connectors at both ends, designed to provide a cost-effective 100GBASE-CR4 link for very short distances. It connects QSFP-100G ports on compatible Cisco switches and networking equipment, making it suitable for connections within racks and between adjacent racks in data centers and enterprise networks.

Advantages

This copper direct-attach cable offers a low-cost, low-latency solution for establishing 100 Gigabit connections over very short distances. With QSFP-to-QSFP connectors and a 2 m length, the cable delivers reliable physical-layer performance without the need for transceivers, reduces power consumption compared with active optical solutions, and is compatible with Cisco QSFP-100G ports.

Suitable for (tasks / use cases)

• Short-range 100G links within a server rack
• Inter-rack connections between adjacent racks
• High-performance computing and data center top-of-rack connectivity
• Low-latency connections for latency-sensitive applications

How to use

Inspect both QSFP ports and the cable ends for damage before installation. Insert each QSFP connector firmly into matching QSFP-100G ports on the networking devices until the latch engages. Route the cable to avoid sharp bends and mechanical stress; maintain the recommended bend radius. The connection is passive—no additional transceivers or power sources are required. Verify link status and speed on the devices after insertion.

Usage recommendations

Use this 2 m Cisco QSFP copper direct-attach cable for short, high-bandwidth links inside racks or between adjacent racks. Do not use for links exceeding the recommended short-reach distance for copper DACs. Store and handle the cable to avoid kinks and contamination of the connector interfaces.
