With deployment and continuous development of optical routes, the issues concerning the thermal loading of erbium-doped optical fibres become more and more relevant. As we were able to see a significant expansion of optical communication systems in the recent years, it was also necessary to find ways for bridging longer distances between individual points of the optical route. Modern optical telecommunication...
In this article the composite author dealt with measurement possibilities of polarization states of light source emitting 1550 nm which was affected by atmospherically transmission environment in special acrylate box 2.5 m long. The Polarimeter Thorlabs TXP 5004 and the External Sensor Head PAN5710IR3 measured the changes of polarization parameters, ellipticity and azimuth, defining placement on the...
This article is dealing with fiber optics application into the geological monitoring. The distributed temperature systems (DTS) are optoelectronic devices, which can continuously measure the temperature and strain along optical cables. These systems use the advantageous properties of optical fibers, which can equally act as sensors. Currently, the DTS systems begin to be applied across the entire...
Fiber optic sensors come in useful in the various fields of industry. Advantages of optic fiber sensors are based on the properties of optical fibers and partly profits from their technological development. The fiber optic temperature sensors use different kinds of sensing, all of them reach the upper sensing limit about 600°C. The aim of this article is to introduce a principle of sensor which is...
