Provided are techniques, devices and systems that enable updating of a reportable parameter table database when a reconfigured optical communication path is formed by switching performed by a branching unit in an undersea optical communication transmission system. A processor may obtain system attributes of each respective segment of a number of segments of the reconfigured optical communication path from a first end point to a second endpoint. The system attributes of each respective segment of the number of segments may be evaluated from the first end point to the second endpoint of the reconfigured optical communication path. A reportable parameter table may be generated based on the evaluated system attributes that includes a listing of operational and structural parameters of system from the first endpoint to the second endpoint of the reconfigured optical communication path.

Techniques to generate network simulation scenarios are described. In one embodiment, an apparatus may comprise a records component operative to receive an example network configuration record; receive an example network operation record; a machine learning management component operative to generate a network operation model using a machine learning component based on the example network configuration record as an example input and the example network operation record as an example output; and a system-test component operative to receive a system-test network configuration record; and generate a system-test network operation record based on the system-test network configuration record using the network operation model. Other embodiments are described and claimed.

Techniques to generate network simulation scenarios

An embodiment of the present disclosure includes an RPC architecture that includes a central manager gateway with a client-facing side that allows for client access via web services protocols such as SOAP and REST. The central manager gateway further includes a server-facing side that can communicate with a plurality of network elements, with each network element implementing a common IDL architecture and RPC manager instance. Each of the network elements, and in particular their RPC manager instance, may communicate with other RPC manager instances to 'learn' the network topology for the system and maintain a topology database for purposes of exposing a naming service, e.g., a CORBA naming service. The network elements may elect one master element while the others remain as slaves. The central manager gateway may automatically locate the master network element and forward client requests to the same for servicing.

A system and method consistent with the present disclosure allows for a single NMS system to manage data access and control for N number of customer domains and associated users. In particular, an NMS consistent with the present disclosure may include a configuration that partitions the optical communication system by domain. For each domain, partitioning can further define per-user access constraints and privileges including access to specific equipment by, for instance, fiber pair designation, wavelength designation, specifically identified hardware elements, component categories, or any combination thereof. The NMS system may utilize a proxy server approach to authentication, e.g., using RADIUS, that allows for each party/customer to maintain separate authentication databases and equipment-specific constraints. The NMS may therefore validate users and enforce domain restrictions via the partitioning information such that each user has a secure 'view' of only those portions of the system associated with their particular domain.

A system and method consistent with the present disclosure provides for automated line monitoring system (LMS) baselining that enables capturing and updating of operational parameters specific to each repeater and associated undersea elements based on high loss loopback (HLLB) data. The captured operational parameters may then be utilized to satisfy queries targeting specific undersea elements in a Command-Response (CR) fashion. Therefore, command-response functionality may be achieved without the added cost, complexity and lifespan issues related to deploying undersea elements with on-board CR circuitry. As generally referred to herein, operational parameters include any parameter that may be derived directly or indirectly from HLLB data. Some example non-limiting examples of operational parameters include span gain loss, input power, output power, gain, and gain tilt.

Techniques for parameter reporting of elements in an optical transmission system using high loss loopback (HLLB) data and a line monitoring system implementing the same

A system and method for automatically calibrating loopback data in a line monitoring system of an optical communication system. Extra peaks in loopback data are calibrated out of the loopback data used by the system by identifying pairs of peaks in the loopback data associated with test signal transmissions through the same high loss loopback path from opposite ends of the optical transmission path.

Automatic calibration of loopback data in line monitoring systems

In general, a system and method consistent with the present disclosure provides automated line monitoring using a machine learning fault classifier for determining whether a signature associated with the high loss loopback (HLLB) data matches a predetermined fault signature. The fault classifier may be applied to signatures generated in response to line monitoring signals of two different wavelengths. A fault may be reported only if the fault classifier indicates a fault in response to the signature for both wavelengths. A second fault classifier may also be used and a fault may be reported only if both the first and second fault classifiers indicate a fault in response to the signature for both wavelengths. A system consistent with the present disclosure may also, or alternatively, be configured to report the value of a pump degradation, span loss, or repeater failure fault, and may also, or alternatively, report the directionality of a span loss fault or the location of a fiber break fault.

Fault detection and reporting in line monitoring systems

Techniques for providing high-resolution, standard-format output for line monitoring equipment (LME) of a wavelength division multiplexed (WDM) communication system is disclosed. LME may transmit a plurality of LME test signals via an optical path of the WDM system and perform gain measurements on reflections associated with the same at predetermined intervals. Gain measurements for each of the plurality of LME test signals may be normalized and filtered to derive LME peak data. The WDM communication system may perform full scans with data points totaling millions/billions (e.g., depending on system length, fiber type, and number of transmitted LME test signals or test pulses) and normalize the same into a relatively small number of resulting data points within the LME peak data. The WDM system may then output an LME results file in a standard format which is compatible with commercial viewers and optical time domain reflectometer (OTDR) equipment.

A wet plant manager (WPM) platform is disclosed in accordance with an embodiment of the present disclosure, and supports management of Smart Undersea Network Elements (SUNEs) by providing an abstracted view of the same to higher level network management functions within an optical communication system. The optical communication system can include an optical cable system extending between two or more cable landing stations (CLSs). Each CLS may execute a respective instance of a WPM platform service, with the collective WPM platform performing self-coordination such that only one instance of a WPM service is 'active' at any given time. The active WPM service supports a plurality of network topologies architected around SUNEs and 'bridges' them such that requests to communicate with a particular SUNE get handled in a transparent manner without the requesters specific knowledge of which command/response (CR) telemetry path was utilized to satisfy the request.

Optical communication system with distributed wet plant manager

Techniques for managing a data communication network (DCN) are disclosed, in accordance with an embodiment, and provide planning, maintenance, and validation (e.g., auditing) functionality for the purpose of managing network elements across a plurality of stations/locations associated with an optical communication network. In accordance with an embodiment, a computing device includes a DCN configuration interface and engine. The DCN configuration interface enables modeling of a DCN based on a plurality of user-provided parameters and constraints. The DCN configuration interface may then generate settings files in accordance with the DCN model. The DCN configuration interface further allows previously-generated configuration files to be read in for the purpose of performing updates, adding new stations, new network elements, new equipment types, new equipment models, and so on. Therefore, the DCN configuration interface disclosed herein reduces or eliminates address conflicts and other misconfigurations during provisioning.
