Selection problems of optical fiber for transport telecommunication new generation networks

The paper presents an analysis of the main trends in the development of transport networks in general, and data transmission technologies in particular. The requirements for fiber-optic transmission lines of transport networks of new generation are formulated. Options and choices of the optical fibers of these lines are considered. In particular, we considered the data transmission on super channel of lines with standard single-mode fibers, few-mode fiber, in a few-mode regime multimode fiber and multicore fiber. The comparison of the channel characteristics for these fibers is executed. In particular, the application with multimode fiber and multicore fiber technologies spatial division multiplexing and MIMO was considered. Presents forecasts for choosing optical fibers for the next generation transport networks.
