摘要： 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. Protection switching may be provided by selectively openable switches disposed in and distributed around the rings.

摘要： 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.

摘要： 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.

摘要： Reducing polarization dependence of a dispersion variation monitor includes receiving an optical signal. The optical signal is split into a first polarized signal having first photons and a second polarized signal having second photons. The first photons are received at a first material of a first detector, where the first material is operable to produce a reaction in response to the arrival of a predetermined number of photons. The second photons are received at a second material of a second detector, where the second material is substantially similar to the first material. A first current produced by the first material in response to receiving the first photons and a second current produced by the second material in response to receiving the second photons are monitored. Whether there is wavelength dispersion variation among the plurality of components is established in accordance with the first current and the second current.
