The components of a fiber optic collimator include
The lens takes the spreading light from the fiber and makes it travel in one direction. It typically consists of: Optical fiber section – single-mode fiber (SMF) is most common, but polarization-maintaining (PMF) or multimode fiber (MMF) can also be used. Fiber optic collimators (also called fiber-optic collimators) are crucial optical components that convert the diverging output from an optical fiber into a collimated (parallel) beam, or conversely focus light from free space into a fiber. Fiber couplers, inline photodiodes, WDMs, combiners, circulators, and optical switches provide fundamental building.
