This paper presents the multimode passive optical network for LAN (Local Area Network) application. These networks
should be cheaper and more usable than single-mode structures. The paper presents possibilities of commercial
application of multimode passive networks.
In this paper, an analysis of the construction of symmetrical and asymmetrical passive fiber optic structures is presented, as well as an analysis of the possibilities of using a collision detection method in these structures and the possibilities of transmitting optical signals through structures of this type.
