Abstract
The present invention provides a local access network, having a switching node, a passive remote node connected to an optical network unit, a first optical fiber that provides a dedicated connection between the switching node and the passive remote node, and a second optical fiber that provides a dedicated connection between the switching node and the passive remote node. A first portion of a first fiber-optic cable containing the first optical fiber does not contain any part of the second optical fiber, such that there are independent paths from the switching node to the passive remote node.
