Optical communication infrastructure

Optical cables are used in telecommunications to transmit signals and data over long distances. Transmission medium is optical fiber, and information is transmitted through light. 

 In Serbia, fiber optic cables with capacities from 6 to 240 optical fibers are used the most. At the entrance of the optical fiber, the electrical signal is converted to light by a light or laser diode, and at reception it is converted again to an electrical signal by a photodiode.


Fiber optic cable division:

  1. Monomode (singlemode-SMF), thinner and allow one beam of light to spread.
  2.  Multimode (multimode-IMF), thicker and allow more air to flow from different sources.

Advantages of optical cables are:

Their far smaller dimensions than copper cables, the ability to transmit large amounts of information, a slight attenuation of the signal allowing up to 200 km without signal amplification, less weight per meter, easier laying both in the ground and under water, on poles or overhead power lines all lower price insensitivity to electrical interference, water, low and high temperatures.Optički kablovi su jedino osetljivi na radioaktivno zračenje.
