What are fiber optic cables made of?

Fiber optic cables consist of several components: core, cladding, jacket and strength member.



Fiber Optic Cable


At the heart is the optical fiber itself, which is a continuous strand of ultra-thin glass.


Inside the core are two highly specialized coatings of glass called cladding and sheathing.


When an imperceptible optical signal travels along the cable, the cladding reflects it back through reflections from the cable wall.


Jackets protect delicate optical fibers from mechanical damage and environmental influences.


Finally, reinforcements such as aramid yarn or steel wire are used to strengthen and protect the cable further from bending or tensile forces. Together, these components form a fiber optic cable that transmits optical signals over long distances without signal loss or interference.
