Abstract

Distributive technique bases on selective mode excitation into few- or multimode trunk optical fiber. The technique enables increasing the level of data protection in the systems of short and middle line lengths. If intrusion to the optical trunk occurs, summarized signal of different modes is registered containing mixed parts of the initial signal. Therefore, adequate decoding of the illegally read signal cannot be provided. Available lengths of trunk lines are discussed considering the level of intermodal coupling into the trunk fiber. It is shown that intermodal coupling does not decrease the level of data protection in the system.
