Direct attach cable, short for DAC, is a form of high speed cable with “transceivers” on either end. They can be used to connect switches to routers or servers. They are becoming increasingly popular in the network industry and widely applied in storage area network, data center, and high-performance computing connectivity etc. The DAC has the advantage of cost-effectiveness compared with the regular optics.
