Principle of Three-Fiber Collimator
A fiber collimator changes light from a fiber into a straight, parallel beam. It is composed of a single-mode pigtail fiber as well as a collimating lens, and it has the characteristics of low insertion loss, high return loss, long working. " They convert divergent light emitted from fibers into collimated beams or focus parallel beams into fiber cores, ensuring stable and high-quality signal transmission.
