New passive optical network architectures for fiber-to-the-desk application

We propose new network architectues that will compet with the existing copper based local area networks in overall cost and still offer a better prformance: less downtime, lower mantenance cost, extended geometrical spans and larger headroom for future capacity increase. Presented passive fiber optic network topologies represent a novel approach in fiber-t-the-desk applications. In the proposed architectures the generally accepted standard for LAN, namely Fast Ethernet is used in order to provide cheaper implementation of the networks. Moreover, an architecture is presented based on ATM which is supposed to be the future protocol for LAN's.
