Back to old time in 1970 when Charles K.Kao and George Hockham firstly developed the optical fibers, by using the Corning Glass Works. This device could be used for communication for about 20dB/km.  Later on this technology was developed by many scientists and result to more beneficial needs for communication equipments and great progress to this Information age.

Through these fiber optic systems it is able to transmit information from one spot to another by transferring pulses of light. These pulses of light then will go through optical fiber. These optical fibers have replaced the conventional copper wire, and this become more cost effective nowadays. It is used in many fields such as for telephone and television signals and internet. Many companies are producing this product, including the one with the site of Icc.com which offer the Cat6 cables.

This fiber optic systems done in several steps, first is generate optical signal and then with the use of transmitter it will communicate the signal all along the fiber. And at the end it is changed into electrical signal. This modern technology is nowadays very much used in developed countries; it gives more advantages for the needs of electrical transmission. That is why it is called the revolution in the telecommunication system.
