Final answer:
To correctly pull optical fiber cables, the pull wire or tape must be attached to the cable's strength member to prevent damage to the fibers.
Step-by-step explanation:
The proper method of pulling optical fiber cables is to attach the pull wire or tape to the strength member of the cable. Optical fibers are used in fiber optics for the transmission of light down fibers of plastic or glass, utilizing the principle of total internal reflection. The construction of optical fiber includes a core, cladding, and a protective layer, wherein the cladding material has a lower index of refraction than the core to prevent light from being transmitted between fibers in a bundle. During the installation process, it is critical to utilize the strength member of the cable for pulling to avoid damaging the delicate fibers that are responsible for transmitting data.
