What are fiber optic cables and how do they work?

Fiber optic cables are thin strands of glass or plastic that transmit data as light signals. They work by converting electrical signals into light, which is then transmitted through the fiber optic cable. The light signal is made up of a series of pulses that correspond to the 1s and 0s of digital data. At the receiving end, the light signal is converted back into an electrical signal, allowing the data to be read and processed.

Fiber optic cables are made up of several layers, including the core, cladding, and coating. The core is the thin glass or plastic center of the fiber, where the light signal is transmitted. The cladding is a layer of material that surrounds the core and helps to reflect the light signal back into the core. The coating is a protective layer that surrounds the cladding and helps to protect the fiber from damage.

Are fiber optic cables fragile and prone to breakage?

Fiber optic cables are often perceived as being fragile and prone to breakage, but this is not entirely accurate. While it is true that fiber optic cables can be damaged if they are bent or flexed too much, they are actually quite durable and can withstand a significant amount of stress. In fact, many fiber optic cables are designed to be flexible and can be bent and twisted without sustaining damage.

However, fiber optic cables can be damaged if they are subjected to excessive stress or if they are not handled properly. For example, if a fiber optic cable is bent too sharply or if it is pulled too tightly, it can cause the fibers to break or become damaged. Additionally, fiber optic cables can be damaged by environmental factors such as extreme temperatures, moisture, or exposure to chemicals.

What are some common causes of damage to fiber optic cables?
