## Long description

The CBO QSFP28-DAC-1M is a 1‑meter passive copper direct attach cable that provides 100G connectivity for equipment equipped with QSFP28 ports. Engineered for short-reach links, this DAC cable offers a compact physical profile, low latency and plug-and-play operation without the need for external power or transceivers. It is suitable for high-density environments such as data center racks and top-of-rack switch interconnects where reliable 100G copper connections are required.
Advantages
The passive copper design delivers low power consumption and negligible added latency compared with active or optical alternatives. Its one-meter length minimizes signal degradation over short distances while keeping cable management tidy in rack and modular deployments. The integrated QSFP28 connectors simplify installation and reduce the number of separate components needed for a 100G link.
Suitable for
Short-distance connections between switches in a rack or adjacent racks
Direct server-to-switch or server-to-NIC 100G links
Top-of-rack and end-of-row network topologies requiring compact cabling
Key specifications
Connector type: QSFP28 to QSFP28 passive copper
Nominal length: 1 meter
Data rate: 100 Gbit/s
Cable medium: copper twinax (DAC)
Power requirement: passive, no external power or transceivers required
Typical use: short-reach direct attach interconnects
How to use
Install the cable by inserting each QSFP28 connector into the corresponding port until the latch engages. Ensure ports on both devices are QSFP28-compatible and that firmware or drivers on connected equipment support passive DAC links at 100G. Avoid excessive bending or strain on the cable and secure cable runs within the rack to prevent movement. For best results, power down or follow hot-swap guidance from your equipment vendor if recommended when connecting or disconnecting high-speed links.
Usage recommendations
Choose this 1 m passive DAC for short, high-density links inside racks or between adjacent racks where cost-effective, low-latency 100G connectivity is required. Verify compatibility with your switch or NIC vendor documentation and maintain correct airflow and cable management to preserve signal integrity.
