What is the working principle of a spectrometer spectrometer spectrometer
A spectrometer splits light into colors to show what materials are made of by measuring light's intensity and wavelength. It works by letting light enter through a slit, then using optics and a grating or prism to separate colors, which a detector measures and displays as a graph. An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials. The word "spectrum" refers to the range of wavelengths or frequencies of electromagnetic radiation, which includes visible light, ultraviolet (UV) light, infrared (IR).

DCD-2 Differential Relay Protection Working Principle
This relay works on the basis of the quantitative difference that occurs in the outgoing and incoming current levels, surpassing a certain percentage of the total current. DCD-2A differential relay (hereinafter referred to as the relay) is used for primary protection in single-phase differential protection lines of two or three winding power transformers and ac generators. Principle of Operation: These relays activate based on discrepancies in electrical quantities. The aim of this technical article is to cover the most important principles of four fundamental relay protections: overcurrent, directional overcurrent, distance and differential for transmission lines, power transformers and busbars.

Working principle of optical fiber connectors
Fiber cable can be very flexible, but traditional fiber's loss increases greatly if the fiber is bent with a radius smaller than around 30 mm. Bendable fibers, targeted toward easier installation in home environments, have been standardized as ITU-T. The optical fiber connector is to precisely butt the two end faces of the optical fiber, so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent, and the impact on the system due to its involvement in the optical link is. Typical bandwidths for multimode (MM) fibers are between 200 and 600MHz-km and >10GHz-km for single mode (SM) fibers.

Working principle of optical cable pulling
Blowing uses continuous airflow or water flow to suspend and push the cable forward through the duct. Pulling relies on mechanical traction applied via rope, winch, or pulling eye. Fiber optic cable is surprisingly strong, durable and pliable; however, several best practices should be followed to ensure a successful cable installation. While both techniques achieve the same goal—placing fiber cables inside ducts—their engineering mechanics, tension characteristics, duct preparation requirements, and environmental.
