## Summary description

Direct-attach copper (DAC) cable CBO QSFP-100G-C2M is a 3-meter passive twinax assembly for 100G QSFP ports. Designed for short-reach high-speed connections between switches, routers and servers, it provides a low-latency, energy-efficient link without transceivers. Suitable for data center top-of-rack and server-to-switch interconnects.

## Long description

The DAC cable CBO QSFP-100G-C2M 100G passive direct-attach twinax, 3 m is a 3‑metre passive twinax copper assembly designed for 100G QSFP ports. It offers a direct-attach alternative to optical transceivers for short-reach connections in data centers, enabling low-latency, energy-efficient links between switches, routers and servers. The cable is intended for use where reliable high-throughput, short-distance connectivity is required without the cost and power consumption of active optical modules.
Advantages
This passive twinax cable delivers high-bandwidth 100G performance with minimal latency and reduced power draw compared with optical transceivers. As a direct-attach solution it simplifies installation by connecting directly into QSFP ports, eliminating the need for separate SFP/QSFP modules. The fixed-length copper assembly reduces component count and recurring module costs while providing consistent electrical signal integrity over the specified 3 m distance. Its design is suitable for dense top-of-rack and server-rack environments where short interconnects are required.
Suitable for
Top-of-rack switch to server connections in data centres
Short-reach switch-to-switch interconnects within the same rack or adjacent racks
High-throughput server uplinks requiring low latency
Environments prioritising energy efficiency and reduced operational cost
Key specifications
Connector type: QSFP to QSFP passive direct-attach twinax
Rated data rate: 100 Gbit/s
Cable length: 3 metres
Cable type: Passive twinax copper assembly
Typical use: Short-reach, within-rack or adjacent-rack interconnects
Latency: Low, direct electrical connection (no optical conversion)
How to use
Install the cable by firmly inserting each QSFP connector into the corresponding QSFP port on your switches, routers or servers until the connector latches. Ensure both devices support passive 100G QSFP direct-attach twinax connections and are powered down or in a maintenance state if required by your equipment guidelines. Once connected, verify link status through device management interfaces and monitor for proper negotiation at 100G. Avoid sharp bends and maintain recommended bend radius to preserve signal integrity over the 3 m assembly.
Usage recommendations
Use this passive DAC cable for short-distance, high-bandwidth links inside racks or between adjacent racks. Confirm port compatibility and QSFP form-factor support on both ends before deployment. For longer distances or where optical isolation is required, consider optical transceivers and fibre cabling instead.
