fiber optic cable gives you immunity to interference and greater signal security. it's also c to insulate the fiber's core from the stress associated with use in harsh environments.
the core is a very delicate channel that's used to transport data signals from an optical transmitter to an optical receiver. to help reinforce the core, absorb shock, and provide extra protection against cable bends, fiber cable c an acrylate plastic coating.
in an envir free from the stress of external forces such as temperature, bends, and splices, fiber optic cable can transmit light pulses with minimal attenuation. and although there will always be some attenuation from external forces and other c there are two methods of cable c to help isolate the core: loose-tube and tight-buffer construction.
in loose-tube c the fiber core literally floats within a plastic gel-filled sleeve. surrounded by this protective layer, the core is insulated from temperature extremes, as well as from damaging external forces such as cutting and crushing.
in tight-core c the plastic extrusion method is used to apply a protective coating directly over the fiber coating. this helps the cable withstand even greater crushing forces. but although the tight-buffer design offers greater protection from core breakage, it's more susceptible to stress from temperature variations. plus, even though it's more flexible than loose-tube cable, the tight-buffer design offers less protection from sharp bends or twists.
