Direct Attach Cable (DAC), especially active DAC, is widely used in data centers for short-reach, high-density interconnect.
Key use cases:
Server-to-top-of-rack (ToR) switch connections
Storage and hyperconverged infrastructure links
In-rack and adjacent-rack fabric cabling
Key advantages:
Lower cost: eliminates separate optical transceivers and reduces overall capex
Lower power and latency: no optical-to-electrical conversion
High reliability: fewer components and connectors than optical links
Plug-and-play: simple deployment with broad vendor interoperability
For links up to approximately 5–10 meters, active DACs provide signal conditioning that extends reach and improves signal integrity over passive copper, making them an ideal choice for high-speed, cost-sensitive data center architectures.
Our QC team are testing the DAC, Quality is very important for a project.
