DAC-kabel CBO DAC-QSFP-100G-2M 100G QSFP+ naar QSFP+ Direct Attach, 2 m

CBO DAC-QSFP-100G-2M is a 2-meter direct attach copper (DAC) cable with QSFP+ to QSFP+ connectors designed for 100G links. The cable provides a short-range, low-latency physical connection for compatible QSFP+ ports in switches, routers and servers. It is intended for high-density environments where a reliable 100G link with low power consumption and minimal signal processing is required.

Advantages

The DAC cable delivers a cost-effective and power-efficient alternative to optical transceivers for short-reach 100G interconnects. Because it uses a fixed copper assembly with integrated QSFP+ connectors, it offers low latency and simplified deployment without the need for separate transceiver modules. The 2 m length balances reach and cable management in rack and cabinet topologies and supports high port density interconnections with predictable electrical characteristics.

Suitable for

• Data center switch-to-switch uplinks and aggregation at 100G
• Server to top-of-rack or leaf switch connections in high-performance clusters
• Short-range interconnects within racks and between adjacent racks
• Environments where reduced power consumption and low latency are priorities

Key specifications

• Connector type: QSFP+ to QSFP+
• Nominal data rate: 100 Gbit/s
• Cable type: direct attach copper (DAC)
• Length: 2 meters
• Usage range: short-reach, within racks or between adjacent racks
• Typical latency: minimal, electrical passive interconnect
• Power profile: lower power consumption compared with optical transceiver solutions

How to use

Install the cable by inserting each QSFP+ connector securely into matching QSFP+ ports on network devices. Ensure that host devices support passive DAC assemblies and are powered off or in maintenance state if required by the vendor before hot-plugging. Route the cable to avoid sharp bends and excessive mechanical strain; maintain recommended bend radius to preserve signal integrity. Verify 100G link status and port configuration in the device management interface after installation.

Recommendations

Use the DAC cable for short-distance, high-bandwidth connections where rack-level or adjacent-rack placement is possible. Confirm compatibility with the QSFP+ ports of your switches, routers or servers in vendor documentation and firmware release notes. For longer distances or flexible port configurations consider optical solutions instead of direct attach copper.
