  • Patent number: 6327400
    Abstract: A point-to-multipoint protected network and related equipment for providing protection against fiber and/or interface failures while reducing or eliminating fiber redundancy requirements. The head end is coupled to a ring network comprised of one fiber via a passive splitter which sends the downstream signal out in both the clockwise and counterclockwise directions. Each network terminal is coupled to the ring through an optical circuit comprising a 1:2 optical switch and two passive optical taps. The terminal is coupled to the single terminal side of the 1:2 switch while the two terminals of the double terminal side of the switch are coupled to the ring in opposing directions, i.e., clockwise and counterclockwise, respectively. The two terminals of the double terminal side of the optical switch are each coupled to the ring via a passive optical tap. Other ring and star network embodiments are disclosed.
