Nonmetallic fiber strands under the jacket that provide strength and flexibility to Optical Fiber Cable are called

• A. Strength Member
• B. Buffer layer
• C. Jacket
• D. Core

Answer: (A)

The main idea here is the function of components that give a fiber optic cable its strength and flexibility without carrying light. Those nonmetallic fiber strands placed under the jacket are strength members. They primarily resist tensile loads, so when the cable is pulled during installation or subjected to bending and tension in use, the delicate glass core stays intact. Aramid fibers like Kevlar are common examples of these strength members. This differs from the core, which is the glass path that carries light, and from the buffer layer (the protective coating around the fiber) and the jacket (the outer protective shell of the cable). The buffer helps guard against moisture and microbending, while the jacket protects the assembly from environmental factors. But the role of withstanding tension comes from the strength members, making them the correct term.
