The following thesis introduces modern technology of optical communication which can produce faster and more effective transmitting of bigger amounts of data in optical access network. It is called wavelength division multiplexing – WDM, which is integrated in passive optical network – PON. The purpose of introductory part of the thesis is to describe architecture design of passive optical network system and standardization of technologies throughout history until now, including also the directions for the future.
The core of the thesis is a technical explanation of the WDM technology with several elements that are needed for its operation and the possibilities of realization in passive optical network. Here we can read about the problems that accure to architects while designing and building this kind of optical networks. For a broader picture this part of the thesis also includes the comparison of different technologies and outlines their advantages and disadvantages.
Practical experiment is covered in the last part of the thesis. I tried to realise low-cost but still effective Fabry-Perot (FP) laser transmitter with seed light source, which could replace expensive solutions of transmitters in WDM-PON technology.
