摘要： A method and system for distributed fault sensing and recovery in a communication system. A master controller is provided in each cable station of the system. Each master controller receives local alarms, e.g. aggregated alarms from associated shelf controllers, and may receive remote alarms from other master controllers. Local and remote alarms are compared to a profile provisioned in the master controllers for determining whether to perform a fault recovery function.

摘要： A method for handling a fiber line fault is provided. The method includes: loading, by a station, an indication signal carrying alarm suppression information onto an optical signal to be output to a downstream fiber of the station upon detection of a fault on upstream fiber line; keeping in a normal working status, by a downstream station upon a receipt of the optical signal with the indication signal. The various embodiments of the present disclosure suppress alarms from downstream amplifier stations which are not adjacent to the failure link and further suppress APR or APSD procedures according to the alarms.

摘要： A method of coordinating channel power information in a wavelength division multiplexed (WDM) optical communication system is disclosed. The method determines weighting values for each channel of the WDM signal based on channel launch powers. A source data object may used to transmit the channel weights and channel information from network elements having channel sources such as transmitters to downstream network elements. Block data objects may be used to identify channel blocks in the system and are also transmitted downstream. The source and block objects may be correlated to determine which channels are in-view at a particular point in the network and thereby determine which of the channel weights should be used as a basis for managing the network at that point. A WDM system is also disclosed which may actively control channel launch powers and feed the adjusted launch powers into the method of coordinating channel power information.

摘要： The present invention provides a subscriber line terminal device, which enables identification of the cause of abnormality when abnormality is detected in remote monitoring of a subscriber line terminating device connected to the terminal device via an optical fiber. The terminal device receives a plurality of monitoring signals sent from the terminating device via the optical fiber, the plurality of monitoring signals indicating normality or abnormality of a plurality of monitored items in the terminating device respectively. When two or more among the plurality of monitoring signals indicates abnormality, the terminal device selects a monitoring signal with high order of priority from among the two or more monitoring signals indicating abnormality, based on a prescribed order of priority.

摘要： To make it possible to detect faults of optical fibers only by allowing the Master unit side to monitor those fibers in an optical transmission system for bilateral communication of analog optical signals by use of two-route optical fibers between the Master and Slave units. An oscillator of a Master unit oscillates a monitoring signal having a frequency different from that of the RF multiplex signal, a composition means synthesizes these two signals, and a light emission means transmits the synthesized signal to a light reception means of a Slave unit via a downlink optical fiber. A filter means at the Slave unit separates the monitoring signal from the received optical signal, the Slave composition means synthesizes the separated signal and the RF multiplex signal, and a light emission means converts the synthesized signal into an optical signal having a constant average optical power and transmits it to a light reception means at the Master unit via an uplink optical fiber. A detection means at the Master unit detects an average photo-electric power of the received optical signal, a filter means separates the monitoring signal from the concerned optical signal, and a detection means detects the level of thus separated signal.

摘要： An alarm control method allowing easy localization of a failure in an optical communications network is disclosed. An optical signal from a signal transmitter is monitored to produce an alarm information signal indicating whether the optical signal is normally inputted. The optical signal and an optical control signal including the alarm information signal is multiplexed and transmitted to an optical receiver through an optical transmission line. When receiving the optical control signal and the optical signal from the optical transmitter, the optical receiver determines whether the optical signal is normally received. When not normally received, transmission of a receiver-side alarm signal to a management system is controlled depending on whether the alarm information signal indicates that the optical signal has been normally inputted at the optical transmitter.

摘要： Optical supervisory channels are provided in an optical fiber network by receiving, in a first network element (10), a first optical supervisory channel signal (12) at a first wavelength (&lgr;1) from a first direction (14) on a first optical fiber (16), and by transmitting, from the first network element (10), a second optical supervisory channel signal (18) at a second wavelength (&lgr;2) in a second direction (20) and also on the first optical fiber (16). An amplified optical wavelength division multiplexed transmission system utilizing these supervisory signals divides a revenue-traffic amplifying region of an optical amplifier, with a lower portion being used for transmission in the first direction and an upper portion being used for transmission in the second direction. Both the first and second wavelengths are located outside of a flat-gain amplifying region of the optical amplifier.
