Types Of Stack Cables


The first type of stack cable is the Direct Attach Cable (DAC), which offers a cost-effective solution for short-reach interconnects. DAC cables are composed of copper wires and are directly connected to the ports of network switches or servers. They provide high bandwidth and low latency, making them ideal for data center environments where speed is crucial. DAC cables are available in various lengths to accommodate different network configurations.

Active Optical Cables (AOC) are another type of stack cable used for high-speed interconnects over longer distances. Instead of copper wires, AOCs utilize optical fibers to transmit data. These cables have built-in transceivers that convert electrical signals into optical signals and vice versa. AOCs offer excellent signal integrity, low power consumption, and immunity to electromagnetic interference. They are commonly used in applications that require high bandwidth and reliable connectivity.

Passive Copper Cables are stack cables that consist of copper wires with no active components. These cables are an economical choice for short-distance interconnects within a rack or between adjacent racks. Passive copper cables offer low power consumption and low signal distortion. They are relatively inexpensive compared to DAC and AOC cables but have limited reach. They are commonly used in local area networks (LANs) and small-scale data center setups.
