The influence of gamma radiation on polarization mode dispersion of fibers applied in communications

The fiber optics technology is constantly being developed, and is becoming an essential component of contemporary communications, medicine and industry. Fibers, their connections and system components play a major role in optical signal transmission, telecommunications, power transmission, and sensing processes using fiber technology. The two main light propagation characteristics of an optical fiber are attenuation and dispersion. The possibility of controling these parameters is of utmost importance for obtaining the requested transmission quality. This paper reports on an investigation to determine the influence of gamma radiation of 60Co on the variation of optical fiber propagation parameters, such as polarization mode dispersion. In addition, it also considers chosen topics in the field of fiber optics technology. Tehnologija optickih vlakana konstantno se razvija i postaje glavna komponenta u savremenim komunikacijama, medicini i industriji. Opticka vlakna, njihovi spojevi i komponente sistema imaju glavnu ulogu u prenosu optickih signala, u telekomunikacijama, prenosu snage ili u procesima, gde se koriste kao senzori. Dve najvaznije propagacione karakteristike optickog signala u vlaknu su slabljenje i disperzija. Mogucnost kontrole ovih parametara je vrlo vazna za postizanje zahtevanog kvaliteta prenosa. U ovom radu, analizirali smo odredjena pitanja u vezi sa optickim vlaknima i nase eksperimente sa uticajem gama zracenja 60Co, na propagacione karakteristike vlakana, kao sto je polarizaciona disperzija.
