SYSTEM FOR INTERCONNECTING NODES ATTACHED TO A PASSIVE OPTICAL NETWORK

摘要

A system for interconnecting one or more leaf nodes attached to the leaves of an optical distribution network (ODN), comprising: A first and a second optical distribution network respectively comprising a remote node for distributing signals from a central office and/or an optical line terminal to a plurality of leaf nodes connected to said optical distribution network; a link connecting a first leaf node connected to the first optical distribution network to a second leaf node connected to the second optical distribution network, wherein the remote node of the second optical distribution network is adapted to forward an optical signal from said second leaf node which has received the signal from said first leaf node to the other leaf nodes of said second optical distribution network.

1. A system for interconnecting one or more leaf nodes attached to the leaves of an optical distribution network (ODN), comprising:
first and second optical distribution networks respectively comprising a remote node for distributing signals received by said remote node via a trunk feeder fiber from a central office and/or an optical line terminal to a plurality of leaf nodes connected to said optical distribution network; and a link connecting a first leaf node connected to the first optical distribution network to a second leaf node connected to the second optical distribution network, wherein the remote node of the second optical distribution network comprises an input unit being adapted to receive signals from the central office and/or optical line terminal of the second optical distribution network, said remote node further comprising an additional signal path connecting said second leaf node to the input unit of said remote node to enable said remote node to forward an optical signal from said second leaf node which has received the signal from said first leaf node to the other leaf nodes of said second optical distribution network to thereby enable to compensate for a failure in said trunk fiber by routing the signal intended for the leaf nodes of said second optical distribution network to said first optical distribution network, via said first leaf node and said link to said second leaf node and then via the additional signal path to the leaf nodes of said second optical distribution network.
