Proposal of multi-casting network system without switches for distance learning education

In this paper, we have proposed on use of optical fiber splitters instead of a piece of multi-casting network equipment. The optical fiber splitter is a passive device and has lower cost than the multi-casting network switches do. We tried one point to multipoint communication use of proposed network system containing an optical fiber splitter. It is found that image signal quality and image signal delay time in case of using on optical fiber splitter are the same as using multi-casting network switches.
