Paper Abstract

At the present time there are a lot of optical fibers used by telecommunication companies for the data transmission. For the long-distance communications the single-mode fibers are being used for their promising values of parameters like attenuation and dispersion. These types of fibers are designed for the purpose of data transmission. The transmitted signal should not be affected by the external quantities. On the other side there are many types of optical fibers used as sensors. There are used in biomedicine, aerospace etc. The sensor types of optical fibers can not be used for data transmission because of their unappropriate values of attenuation and dispersion. The key idea of our research is to integrate both types of fibers into one fiber. The principle of sensing is based on redistribution of the optical power between individual modes around the cross-section of the end fiber-face. These fiber should preserve the significant parameters of telecommunication fibers and it should be able to measure some external quantities at he same time. This article shows the fundamental steps which must be done to operate the fiber as a sensor and the communication environment at the same time.
