OTN
OTN (Optical Transport Network) is a technology used in modern telecommunications networks to send large amounts of data over fiber optic cables. Think of it as a highly organized highway system for digital information, designed to carry phone calls, internet traffic, and business data efficiently over long distances. It's like having multiple lanes on a highway where different types of traffic can travel together smoothly without interference. Network engineers work with OTN equipment to ensure reliable and fast data transmission between cities, countries, and continents.
