## Summary description

Cisco QSFP-100G-CU1M= is a 1 m copper direct-attach QSFP to QSFP cable designed for 100G InfiniBand and compatible fiber-optic networking equipment. It features QSFP connectors on both ends and a fixed 1 m length, suitable for short-reach interconnects in data centers, switch-to-switch links, server top-of-rack connections, and high-bandwidth uplinks.

## Long description

Cisco QSFP-100G-CU1M= is a 1 m copper direct-attach cable with QSFP connectors on both ends, designed to carry 100G signals for short-reach interconnects. The cable implements a 100GBASE-CR4 link over copper and is intended for use between QSFP ports on network switches, top-of-rack servers, and adjacent rack equipment in data centers. Its fixed 1 metre length and QSFP-to-QSFP form factor make it a straightforward option for establishing high-bandwidth links where fiber transceivers are not required.
Advantages
The direct-attach copper design provides a low-latency, energy-efficient physical connection without the need for separate transceivers or optical modules. This cable simplifies installation with a plug-and-play QSFP interface and reduces per-link cost for very short runs. Its consistent physical construction supports reliable 100G signaling across short distances and is compatible with equipment that accepts QSFP direct-attach copper assemblies.
Suitable for
 Switch-to-switch 100G links within the same rack or adjacent racks
 Top-of-rack (ToR) uplinks between servers and switches where 1 m reach is adequate
 High-density patching in data center racks and network aggregation points
Key specifications
 Cable type: Direct-attach copper (DAC)
 Connector type: QSFP to QSFP
 Data rate: 100 Gbps (100GBASE-CR4 electrical interface)
 Length: 1 metre (fixed)
 Typical use: Short-reach, rack-to-rack or within-rack interconnects
How to use
Insert each QSFP connector into the corresponding QSFP port on the networking devices until the connector latches. Ensure devices are powered down or follow hot-plug guidance from the equipment manufacturer if performing live installation. After physical connection, verify link status and interface configuration on the network devices; auto-negotiation and link training are typically handled by the equipment. Handle the cable by the connector housings and avoid tight bends or excessive pulling to maintain signal integrity.
Usage recommendations
Use this 1 m QSFP-to-QSFP copper cable for short, cost-sensitive 100G links inside racks or between adjacent racks. Avoid using it for longer distances; for extended runs, consider fiber-based QSFP optics or active cabling. Maintain bend radius and secure cable routing to minimise mechanical strain and preserve performance.
