Abstract
This paper presents a high bend tolerant multimode optical fiber transmission system that is compatible with standard 50 µm graded index multimode fiber, in terms of achievable bandwidth and interconnectivity losses. When the 10 loops of the proposed bend resistive multimode fiber were wrapped around a cylinder of 1.5 mm radius, bend losses below -0.2 dB were achieved in case of experimentally produced fiber. Furthermore, when the section of the proposed bend resistive fiber was inserted between two sections of a standard 50 µm graded index multimode fiber, the total experimental measured loss proved to be below -0.15 dB.
