The working mechanism of low-voltage cabling involves the transmission of electrical currents via insulated copper or fiber optic cables. The current carrying capacity of these cables is relatively minor, making them appropriate for communication networks and security systems. Common voltage levels include 12V, 24V, and 48V This type of wiring is often used to power or transmit data between smaller, low-power devices such as doorbells, thermostats, security cameras, garden lighting, and. They are the bridge between fiber optic cables in the field and the equipment or patch panels that manage them. By combining factory-installed connectors with spliced bare fiber, pigtails ensure that network installers can create fast, reliable, and cost-effective terminations. In particular, anything below 50 volts is considered to be of low voltage.
