## Summary description

CBO DAC Cable QSFP28 SC282801L3M26 3M is a 3-meter QSFP28 direct-attach copper (DAC) link designed for high-speed 100GbE connections between compatible switches, routers and network adapters. It provides a fixed, low-latency physical connection without optics, suitable for short-reach links in data centers, server racks and aggregation switches, offering simplified installation and reduced power consumption.

## Long description

The CBO DAC cable QSFP28 SC282801L3M26 3 m is a QSFP28 direct-attach copper (DAC) cable designed for 100GbE short-reach links in data center environments. This fixed copper connection provides a low-latency, power-efficient alternative to optical transceivers for connections between compatible switches, routers and network adapters. At 3 metres length it is intended for rack-to-rack or within-rack interconnects where a reliable, maintenance-free physical link is required without the complexity of separate transceivers and fiber patching.
Advantages
This QSFP28 DAC cable offers deterministic latency and reduced power consumption compared with optical modules, since no transceiver or optical power budget is required. The integrated connector assemblies simplify installation and reduce component count, lowering potential points of failure. Its passive copper construction enables plug-and-play deployment in compatible 100GbE ports and eliminates the need for optical cleaning or fiber management in short-distance topologies.
Suitable for
Short-reach 100GbE links within server racks or between adjacent racks
High-performance switch-to-switch or adapter-to-switch connections
Data center aggregation and spine-leaf topologies requiring consistent low latency
Environments prioritizing lower power consumption and simplified cabling
Key specifications
Interface type: QSFP28 to QSFP28 direct-attach copper
Nominal data rate: 100 Gigabit Ethernet
Cable length: 3.0 metres
Cable type: Copper twinax, fixed assembly
Typical reach: short-reach (within or between racks)
Latency: low, deterministic electrical connection
Compatibility: intended for devices with QSFP28 ports supporting DAC interconnects
How to use
Power off or follow hot-plug guidance of your equipment as recommended by the switch or adapter manufacturer, then insert each QSFP28 plug into the corresponding port until the connector latches. Ensure the port configuration on both ends is set for a copper DAC link if device firmware requires selection. After connection, verify link status via the device management interface and check for correct speed and lane mapping. For removal, depress the latch and gently withdraw the connector to avoid mechanical stress on the port.
Usage recommendations
Use the cable for short, high-speed interconnects inside racks or between adjacent racks where 3 metres provides sufficient reach. Avoid routing through tight bends or subjecting the cable to sustained mechanical strain; maintain bend radii recommended by equipment vendors. Confirm port compatibility and firmware support for DAC assemblies before deployment, and keep the connectors free of contaminants—although direct-attach copper eliminates optical cleaning requirements, good handling practices help maintain reliable electrical contact.
