FAQ
1. What is direct attach copper cable?
A: A direct attach copper cable, also known as a DAC cable, is a type of high-speed data transmission cable commonly used in networking applications. It is designed to connect networking devices such as switches, routers, and servers over short distances, typically within the same rack or data center.
2. Why use DAC cable?
A: DAC cables are typically more affordable compared to optical transceivers and fiber optic cables, offering a cost-effective alternative for short-range connections where extensive transmission distances are not necessary.
3. What is the maximum length of direct attached copper cable?
A：The maximum length of a DAC cable depends on the type and speed of the connection. Generally, DAC cables are limited to relatively short distances compared to fiber optic cables. For example, 10GbE and 25GbE DAC cables typically have a maximum length of up to 5 meters (16.4 feet), while 40GbE and 100GbE DAC cables may have a maximum length of up to 2 meters (6.6 feet) or 5 meters (16.4 feet), depending on the specific cable and equipment requirements.
