## Summary description

Direct attach copper (DAC) cable CBO QSFP-100G-C3M is a 3 m passive 100G connection designed for QSFP ports. It provides a short-reach, low-latency link between compatible switches, routers or network adapters without transceivers. Ideal for top-of-rack, spine-leaf and high-density rack interconnects where reliable 100Gbps connectivity and reduced power consumption are required.

## Long description

Direct attach copper (DAC) cable CBO QSFP-100G-C3M is a 3 meter passive 100G connection engineered for QSFP ports. The cable provides a short-reach, low-latency link between compatible switches, routers or network adapters without using separate optical transceivers. Designed for high-density environments, it delivers reliable 100Gbps connectivity with minimal power consumption and simplified cabling for top-of-rack, spine-leaf and adjacent-rack interconnects.
Advantages
The passive DAC design eliminates the need for external transceivers, reducing component count and operational power draw. With a fixed 3 m length and QSFP-to-QSFP terminated connectors, the cable offers predictable signal performance and low latency suitable for high-throughput fabrics. Its rugged assembly and standardized QSFP interface ensure straightforward installation and compatibility with equipment that accepts QSFP passive copper assemblies.
Suitable for
Top-of-rack switch to switch connections in data centre racks
Spine-leaf interconnects in leaf-spine network architectures
High-density server or switch adjacency where short-reach 100Gbps links are required
Direct connections between network adapters and switches for low-latency applications
Key specifications
Data rate: 100 Gbps (parallel lanes)
Length: 3 meters
Connector type: QSFP to QSFP copper assembly
Design: Passive direct attach copper (DAC)
Typical application: Short-reach, high-bandwidth interconnects
Latency: Low, suitable for high-throughput fabrics
How to use
Install the QSFP-100G-C3M by inserting each QSFP connector into the QSFP port on the two devices to be connected. Ensure both ports support passive QSFP copper assemblies and are powered down or follow hot-plug guidance from the equipment vendor if applicable. After seating the connectors, verify link status and negotiated speed through the device management interface. No additional configuration is required at the cable level beyond verifying physical link and interface settings on the connected devices.
Usage recommendations
Use this 3 m passive DAC where short, direct 100Gbps links are sufficient and where minimizing power and component complexity is a priority. Avoid routing the cable near strong electromagnetic sources and maintain bend radii recommended by the equipment vendor to preserve signal integrity and connector longevity.
