Historical Events in Fiber Optic Technology

When we talk about the history of fiber opitcs, we need to at least start from the year 1880. In fact, the use of light…

All Silica Optical Fiber

Optical fibers can be made of plastic or silica glass. An optical fiber made of silica glass is called Silica fiber or all-glass fiber. The…

All-Dielectric Fiber Optic Cable

An optical fiber cable made entirely of non-metallic components is called All-Dielectric Fiber Optic Cable. Optical fiber cables are designed and manufactured using a combination…
