ABSTRACT:
This invention relates to fiber optic networks for the two way communication of light signals. One optic fiber may carry bidirectional signals to many nodes connected to the optic fiber by bidirectional passive optic couplers. Passive unidirectional to bidirectional passive optic couplers can bridge between bidirectional optic fiber networks and unidirectional fiber optic networks. Thus optical signals can be transported to and from each node to all other nodes such that each node is in contact with all the other nodes on the network.
