The core is the central part of the fiber that carries light signals over long distances. It is typically made of ultra-pure silica glass (SiO2), though some cost-sensitive applications use plastic cores. The core's diameter determines the type of fiber: single-mode fibers have a core around 9 microns for long-distance, high-bandwidth transmission, while multimode fibers have cores of 50–62.5 microns for shorter distances like campus networks .
Surrounding the core is the cladding, which has a lower refractive index than the core. This difference ensures total internal reflection, keeping light signals confined within the core and minimizing signal loss .
The coating or buffer layer protects the delicate core and cladding from physical damage, moisture, and environmental stress. Common materials include acrylate polymers, PVC, or LSZH (low-smoke zero-halogen). This layer also prevents microbending and fiber breakage during handling .
Strength members provide structural support to the cable, preventing stretching, crushing, or breaking. They can be made from aramid fibers (like Kevlar), fiberglass, or steel rods, and are often laid parallel to the fiber to enhance durability, especially in outdoor or long-span installations .
The outer jacket is the protective layer that shields the cable from environmental hazards such as moisture, UV exposure, chemicals, and mechanical damage. Jacket materials vary depending on the application and may include PVC, LSZH, or polyethylene. The jacket also ensures compliance with building codes and fire safety standards .
Some fiber optic cables include ripcords for easier jacket removal during splicing or repairs, and armored layers for extra protection in harsh environments. These enhancements improve installation efficiency and cable longevity . Understanding these components is essential for selecting the right fiber optic cable for specific applications, ensuring optimal signal integrity, durability, and performance.
