Direct Attach Cable (DAC) Overview: A Simple Guide
Direct attach cables (DAC) are interconnect solutions that are widely used in data centers and network environments. This article will explore what DACs are, how to use them (advantages and disadvantages), the classification of DACs and their comparisons to other optical transceivers’ connectivity solutions, and the common data-rate types of DACs. What is a Direct Attach Cable (DAC)? Direct Attach Cable (DAC) is a fixed-length, pre-terminated cable assembly with integrated transceiver modules at both ends. It is typically used to connect network devices, such as switches, routers, and servers, over short distances, typically within or between adjacent racks. DACs are available in copper or fiber optic models, with copper […]
