The operation principle of a fiber mode multiplexer based on cascaded mode selective couplers with a broad bandwidth was demonstrated. The coupling efficiency over the wavelength range from 1515 to 1590 nm varied from 87% to 55%. The experiment for the transfer of information for 58,5 km by the method of multiplexing modes showed that is possible. It can also be expected that the performance of the multiplexer can be improved by efficiently multiplexing degenerative asymmetric modes.
