Is relay protection operated from the electrical box Why
Once a protection relay detects a fault, it will operate automatically and will close down the breaker's trip circuit. This way the faulty circuit will be disconnected from the system and the circuit breaker will be open. It has a set of input terminals for one or more control signals, and a set of operating contact terminals. Engineering use: Relays are used on feeders, transformers, buses, motors, generators, and transmission lines to protect equipment and improve system. In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected.

Is optical fiber considered an electrical circuit
Fiber optic networks are the foundation of modern high-speed communication, powering the global internet. An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light from one end to the other. Such fibers are widely used in fiber-optic communication, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than. Fiber circuits, also known as fiber optic communication systems, have revolutionized the way we transmit data across vast distances. This technology utilizes light pulses to send information through thin strands of glass or plastic fibers, enabling high-speed, reliable, and secure data. The realm of optical circuits stands as a remarkable intersection of physics and engineering, where the elegance of light meets the precision of electronic communication.
