Fiber Optic Cable Specifications
In principle, the optical fiber reflect and refract a light propagating in it. The efficiency of the optical fiber is determined by the purity of the constituents of the glass / glass. The more pure glass material, the less light is absorbed by fiber optics.
To transmit telephone conversations or internet via fiber optics, analog signals are concatenated into a digital signal. A laser transmitter on one end of the cable do on / off signal to transmit each bit. System of modern optical fiber with a single laser can be transmitting millions of bits / second. Or it could be said laser transmitter on and off millions of times / second.
