Data transmission over long distances and in extremely noisy environments make the use of fiber optics the logical choice as a physical transmission medium.
The use of plastic fiber optics allows easy-to-install connections over relative short distances of up to 100 meters. But for distances above this limit the use of glass fiber optic cable is unavoidable.
While distances of up to 4km are easily accomplished with multimode fiber optics, greater distances are the domain of singlemode fiber optics.
It used to be that routing and assembling glass fiber optics created significant problems for the users, but today - thanks to the wider use of glass fiber technology in networking - many companies are offering this work as a service.
