In an immediate mode, the port will interpret a loss of signal on a ... 06/07/07 - 20070127917 - Node device, optical communication network, optical path reserve method and computer-readable medium comprising a program The present invention suppresses an increase of processing time caused by the expansion of network scale, and decreases the probability of occurrence of blocking by reserving optical paths based on the distributed control method, and decreases time to complete the reservation of optical paths. When an optical path is set ... 02/01/07 - 20070025729 - Reconfigurable multichannel (wdm) optical ring network with optical shared protection A reconfigurable multi-channel (WDM) optical ring network with optical shared protection. Preferably, the shared protection is based on a channel optical shared protection ring. The reconfigurable multi-channel (WDM) ring network connects signals between add/drop nodes with reconfigurable optical add/drop multiplexers (ROADM). The ring architecture is used to provide redundant paths ... 01/18/07 - 20070014570 - Simplified remote interface device and method for determining a failure at an optical fiber link terminated with a remote interface device The invention relates to a remote interface device (12) for terminating a remote optical fiber link, with a network input (14), a network output (15), a customer input (17) and a customer output (16) for data signals, characterized in that the device (12) is designed such that during normal operation, ... 10/05/06 - 20060222360 - System and method for protecting optical light-trails Providing protection for a network includes establishing a light-trail through a sequence of nodes of an optical network, where the sequence of nodes is coupled by a first fiber and by a second fiber. Traffic is communicated through a plurality of connections of the light-trail, where a connection is operable ... 08/10/06 - 20060177219 - Link system for photonic cross connect and transmission apparatus Between photonic cross connects (PXCs) 3 and 4, an in-use system path passing through transmission apparatus (WDMs) 5 and 7 are set, and a backup system passing through transmission apparatus (WDMs) 6 and 8 is set. The WDMs 3 and 4 link to the PXCs 5 and 7 and release ... 06/22/06 - 20060133804 - Method and apparatus for protecting optical signals within a wavelength division multiplexed environment A system and method are provided for protecting optical signals within a wavelength division multiplexed (WDM) environment. The system and method utilize a single “protection” wavelength translator device to protect up to N wavelengths. The system and method utilize N+1 wavelength translator devices in order to provide protected transport for ... 05/04/06 - 20060093353 - Optical access node Optical access nodes (1) comprising optical line terminations (31,32) and comprising optical components (41,42) coupled to the optical line terminations (31,32) are provided with switching means (50-52) for coupling a redundant optical line termination (60) to the optical components (41,42). This redundant optical line termination (60) forms a substitute for ... 03/23/06 - 20060062573 - Mobile communication system The present invention makes improvements in a mobile communication system that performs a communication via a communication network provided in a mobile body to execute a data transfer. The present system comprises a plurality of nodes, a path control device which receives data from the nodes respectively, selects a path ... 08/25/05 - 20050185954 - Reroutable protection schemes of an optical network Reroutable protection schemes of an optical network are described herein. In one embodiment, an access node detects that at least a portion of a first path of an optical circuit fails based on a loss of a light of the at least a portion of the first path. In response ... 08/18/05 - 20050180746 - Wavelength and filter arrangement for wdm networks In a ring having first and second adjacent nodes, and two fibers carrying information between the first and second nodes, the first fiber carries information in one direction, while the second fiber carries information in another direction. Each fiber includes wavelength capacity allocated to working and protection traffic. The working ... 08/04/05 - 20050169629 - Diagnosis method for standby system of optical ring network An object of the invention is to provide a diagnosis method for standby systems in an optical ring network having a redundant configuration, which can confirm normal states of standby systems in all optical transmission apparatuses on the network, even during operations of active systems. To this end, in the ... 07/07/05 - 20050147410 - Method and system configured for providing passive optical network fiber protection A method for facilitating passive optical network fiber protection comprises facilitating transmission of bi-directional traffic utilizing a first optical fiber connected between a first port interface of an optical line termination and a first upstream fiber termination of a splitter, and facilitating fiber protection functionality utilizing a second optical fiber ... 07/07/05 - 20050147409 - Utilizing the protecting bandwidth in a sonet network A system provides more cost and bandwidth efficient utilization of a SONET network having both a Working path and a Protection path by using both communication paths to carry data.
