Is optical fiber cable made of copper or iron

Contrary to popular belief, fiber optic cables do not contain copper. Instead, they consist primarily of glass or plastic fibers that transmit data using light signals. These fibers are surrounded by protective coatings made of materials such as polymer or epoxy resin. Fiber optic cables are designed to provide high-speed, no-signal-loss, and EMI-free communication in telecommunication, powergrid, datacenter, broadband, and industrial applications. Each optical cable is constructed using a precise combination of optical fibers, strength members, buffer tubes. Fiber optic cables use pulses of light through ultra-pure glass or plastic fibers to carry information rather than electrical signals.

So, it's about knowing the different types. Its primary method of data transmission relies on light signals traveling through glass or plastic fibers, rendering copper conductors unnecessary for that purpose. Fiber optic cables have revolutionized data transmission. The two core material technologies used in almost all cables are fiber optic, and copper wiring. [PDF]
