Which among the following components of a telephone system uses fiber optics?
Trunks components of a telephone system uses fiber optics.
In telecommunications, trunking is a method for a system to provide network access to many clients by sharing a set of lines or frequencies instead of providing them individually. This is analogous to the structure of a tree with one trunk and many branches.
Trunks are transmission media that handle the communication between offices. A trunk normally handles hundreds or thousands of connections through multiplexing.
A trunk can consist of multiple wires, cables or fiber optic stands bundled together to maximize the available bandwidth in a single physical cable, or it can consist of a single high-capacity link over which many signals are multiplexed.
