The differences between glass and plastic optical fibers

Conventional optical fibers are considered to have poor flexibility, while their diameters are not compact enough. Moreover, such fiber optic systems are relatively fragile and can be damaged by impact, they have a heavy mass because of a relatively large specific gravity. Finally, the cost of the optical fibers, as well as the fiber optic...
