A fiber optic Christmas tree is a type of artificial Christmas tree that uses fiber optic technology to create a dazzling display of colorful lights. Instead of traditional bulbs, the tree is outfitted with thousands of thin, flexible strands of fiber-optic cable that carry light from a single source to each tip of the tree, creating an array of vibrant colors and patterns. Fiber optic Christmas trees are often more energy-efficient than traditional trees and can provide a stunning visual display with minimal setup and maintenance.
