What is the role of strength members in a fiber optic cable?

The role of strength members in a fiber optic cable is to provide support and protect the optical fibers from tension. Fiber optic cables contain delicate glass fibers that transmit light signals, making them vulnerable to breakage if subjected to excessive force or tension. Strength members, usually made from materials such as aramid fiber or steel, are integrated into the cable structure to absorb and distribute external stresses that could otherwise harm the fibers. By reinforcing the cable, strength members help maintain the integrity of the fibers throughout installation and during usage, ensuring reliable performance over time. This aspect is crucial, especially in environments where cables may be exposed to various stresses, such as bending, pulling, or environmental factors. This structural support is what enables fiber optic cables to be installed in a variety of conditions while protecting the sensitive components within.
