Patent number: 7970278Abstract: A flexible open ring optical network includes a plurality of nodes connected by twin or other suitable optical rings. Each node is operable to passively add and passively drop traffic from the rings. The nodes may include a transport element for each ring. The transport elements include an optical splitter element and an optical combiner element. The optical splitter element is operable to passively combine an add signal including local add traffic and a first transport signal including ingress traffic from a coupled optical ring to generate a second transport signal including egress traffic for transmission on the coupled optical ring. The optical combiner element is coupled to the optical splitter element and is operable to passively split a third transport signal including the ingress traffic to generate a drop signal including local drop traffic and a fourth transport signal including the ingress traffic.Type: GrantFiled: May 8, 2007Date of Patent: June 28, 2011Assignee: Fujitsu LimitedInventors: Susumu Kinoshita, Koji Takeguchi, Satoru Odate, Cechan Tian

Patent number: 7116905Abstract: A method and system for control signaling in an open ring optical network includes transmitting traffic in an optical ring. At each of a plurality of nodes along the ring, local traffic is passively added to and passively dropped from the connected ring. At each node, an ingress optical supervisory channel (OSC) signal is dropped from the ring to a managing element. An egress OSC signal is added to the ring from the managing element. The OSC signals may be in-band signal or out-of-band signals.Type: GrantFiled: March 27, 2002Date of Patent: October 3, 2006Assignee: Fujitsu LimitedInventors: Susumu Kinoshita, Koji Takeguchi, Satoru Odate, Cechan Tian

Patent number: 7076163Abstract: The method and system for testing during operation of an open ring network includes opening a ring of the network at the node. Traffic circulating on the ring is dropped in the node to a monitoring element prior to or at the opening of the ring in the node. At the monitoring element, a signal received from the ring is tested. During tested and while the ring is open, traffic continues to be communicated between each node on at least one of the ring or a second ring each connecting the nodes of the network.Type: GrantFiled: March 27, 2002Date of Patent: July 11, 2006Assignee: Fujitsu LimitedInventors: Susumu Kinoshita, Koji Takeguchi, Satoru Odate, Cechan Tian
