## Long description

The Copper DAC cable CBO QSFP28-DAC-2M 100G is a 2‑metre twinax cable with QSFP28 connectors, engineered for short-range 100G links between switches, routers and servers. This passive Direct Attach Copper (DAC) assembly delivers a direct electrical connection without separate optical transceivers, offering a compact, low-latency and energy-efficient option for top-of-rack and data centre aggregation. The cable supports 100 Gigabit data rates and is intended for short-distance interconnects where cost, power consumption and simplicity of installation are priorities.
Advantages
The DAC QSFP28 cable provides a straightforward plug-and-play solution that eliminates the need for separate optical modules, reducing overall system cost and power draw. Its twinax construction ensures low latency and stable signal integrity over the specified 2 m reach, while QSFP28 connectors enable easy compatibility with standard QSFP28 ports on networking equipment. The fixed cable design simplifies inventory and installation in dense rack environments.
Suitable for (tasks / use cases)
 Short-range 100G connections between top-of-rack switches and aggregation switches
 Direct server-to-switch or switch-to-switch links in data centre racks
 High-density patching in network closets and blade server enclosures
 Low-latency interconnects for storage and compute clusters
Key specifications
 Connector type: QSFP28 to QSFP28
 Data rate: 100 Gbit/s
 Length: 2 m
 Cable type: Twinax copper (passive DAC)
 Typical use: Short-reach electrical interconnects in data centres
 Latency: Low, suitable for latency-sensitive applications
How to use
Install the QSFP28-DAC-2M by inserting each QSFP28 connector into the QSFP28 port of the devices to be linked, ensuring correct orientation and a secure seating until the connector latch engages. No separate transceivers, configuration or additional power connections are required. After physical installation, verify link status on connected equipment and confirm the interface is configured for 100G operation if necessary. For removal, disengage the connector latch and pull straight out to avoid stressing the cable assemblies or ports.
Usage recommendations
Use this 2 m copper DAC for short-distance connections within the same rack or adjacent racks. Avoid routing the cable near high-power or high-interference sources, maintain gentle bend radii, and choose passive twinax only where the required reach and port compatibility are confirmed. For longer distances or optical isolation requirements, consider active optical cables or transceiver-based fiber links.
