A thin strand of fiber as transmission carrier of light, which makes total internal reflection of light happens in it and realize transmission. Photoelectric conversion can turn electric signals into optical pulses, which will travel to another side through fiber, then receiving terminal at the other end will turn light pulses into electric signals after receiving them, at last the cable modem will restore the signals.
A fiber optic able is made of fiber, cladding, kevlar, filler, strength members, and cable jacket.
Fiber optic cable is a kind of custom product, so the price varies to different requirements.
Proper installation of fiber optic cables is very important, because it affects the performance of network. Here are some useful tips of cable installation.
Pull cables with useful tools such as pulling eye or pulling grip instead of pulling directly, it will be safer and more efficient.
Never exceed maximum pulling load rate. Using lubricant or automated electric puller is necessary sometimes.
Never exceed the minimum bend radius of the fiber optic cable being installed, because exceeding the minimum bend radius can reduce transmission performance of cable.
Rolling fiber optic cable off the spool rather than pulling is recommended to reduce twist on fiber.
The best way of vertical fiber optic cable installation is to drop the cable down, but not to pull it up.
