Patch cord is an electrical or optical cable, which is used to connect one electronic or optical device to another for signal routing. Patch cords are the most niversal form of Ethernet cable available today. Patch cords are also used to route signals to mixing boards, processors, conditioners, drum machines and other instruments and components.
The features that separate one type of electrical patch cord from another are thickness, safeguarding, length and connectors. Patch cords are most commonly found in computer network rooms. They are used to connect patch panels to network devices. This provides connection to the computers which are blocked in the remote network jacks. The patch cord provide a choice to select between single and multiple modes. With a multi-mode fiber patch in deployment, one need not to worry about the speed, bandwidth and transfer direction of data. With a fundamentally high speed and high accuracy system in place, fiber optic patch cords supply you a low attenuation connection between the fiber network cables or from the cable to the device. These cables are able to carry more than one signal over its length at the same time, in a way that no two signals conflict with each other.
This helps significantly in improving the bandwidth and data transfer rate of the cables. The material used to make these cables is glass and plastic. They are never made of metal. These materials are neither ferromagnetic and nor paramagnetic. While patch and crossover cables may look the same, they are used for two distinctive situations. A crossover cable is reqiured when connecting networks or computers together directly. However, if you are connecting computers to a switch, hub or router a patch cord is what you'll need.
