The core is the central part of the optical fiber, made of high-quality glass or plastic, with a higher refractive index than the surrounding cladding. The core and the cladding are the most critical components of a Optical Fiber cable. Together, they make up the optical fiber, through which data is transmitted in the form of light pulses, guided by the phenomenon of total internal reflection. It is widely used in environments where durability and resilience against external forces are. An armored optical cable is a type of fiber optic cable reinforced with a protective layer—usually corrugated steel tape (STA) or steel wires (SWA) —to shield the internal fibers from external threats such as crushing, rodent bites, moisture, and harsh installation conditions. You will also learn how different aspects of the product can affect budget and design. The metal armor layer effectively protects the fiber core from animal biting, moisture corrosion and various external damages.
