Signal quality in optical networks

Tema ovog završnog rada je Kvaliteta prijenosnog signal preko svjetlovodne mreže. Rad se bavi opisivanjem i mjerenjem svjetlovodne mreže uz osvrt na kvalitetu. Prvi i drugi dio opisuju arhitekturu i elemente svjetlovodne mreže na našem području. Proračun gubitka signala i mjerenja na instalacijama dokazuju kvalitetu izvedbe svjetlovodne mreže. Rezultat ovoga rada je na ukazivanje prednosti koje nudi svjetlovodna mreža u odnosu na današnje bakrene parice ili bežične prijenose i to u zadnjem dijelu petlje koja dolazi do krajnjeg potrošača. Današnji telekomunikacijski prijenos lagano zastarijeva, te je potrebno što brže okrenuti se prema svjetlovodnome prijenosnom sustavu koji je već godinama vrlo malo iskorišten.The theme of this final work is the quality of signal transmission over fiber optic networks. The work deals with the description and measurement of optical network with reference to quality. The first and the second part describe the architecture and elements of the fiber optic network in our area. The calculation of loss of signal and the measuring of the installations prove the quality of the performance of the optical network. The result of this work is to point out the advantages offered by fiber optic network in relation to today's twisted pair copper wire or wireless transmissions and that on the last part which comes to the final consumer. Today's telecommunications transmission is slowly becoming obsolete and because of this it is a need to turn as quickly as possible to the optical transmission system which has been very little used yet
