Passive network components are elements that do not require a power source and do not amplify or regenerate signals. They are essential to network building blocks and perform fundamental functions such as connecting devices, splitting signals, or hosting the active network equipment. These components are typically used with active routers, switches, or hubs to build a complete network.
Some examples of passive network components include:
Network cabinets, Patch panels, Copper and fiber ducts, Copper and fiber optic cables, Connectors, DWDM etc.
