NQMSfiber - remote fiber test system

The ultimate plug-and-play remote fiber test system—monitor critical fibers to ensure that SLAs are met and that the network and the services are always available.

NQMSfiber is a network quality monitoring system that keeps NOC operators and field technicians aware of any fiber-related issues or degradation on a 24/7 basis. NQMSfiber uses a central test system controller and OTDR-based remote test units (RTU) deployed at key locations across the network. NQMSfiber features preventive degradation alerts, flexible alarm management, APIs to integrate with third-party GIS, complete reporting functions and a clear view of the network status. It integrates seamlessly into any existing network management systems.

Monitoring that gives you actionable insights (unlike power-level monitoring)

System capabilities:

24/7 detection, location and tracking of fiber degradations

Lit or dark fiber monitoring capabilities

Statistical learning method for referencing and baselining a fiber route

Web-based element management system (EMS) and remote test unit (RTU)

Turnkey fault-on-map solution with inventory and GIS (OSPInsight)

Plug-ins for out-of-the-box GIS two-way integration

When every minute counts, will you be ready?

Reduce MTTR—find and fix faults before they impact subscribers.

Referencing a fiber from day 1 is crucial to be able to automatically detect and pinpoint issues.

NQMSfiber uses this baseline to compare results and automatically find faults for you.

Without a baseline

  • Is this fiber good or bad?
  • Is it degraded from last time it was tested?
  • Length seems as per documentation so where’s the problem?

With a baseline

  • NQMSfiber automatically identifies a change (degradation) on the fiber being monitored

NQMSfiber provides true preventive maintenance through its unique capability to report slight changes in loss profiles. NQMSfiber detects and pinpoints losses in the 0.1 dB order.

Something seemingly insignificant (i.e., less than 1 dB degradation) on an OTDR trace can have significant impacts and lead to an outage–NQMSfiber helps you stay on top of your network's health and avoid issues early on.

Time to understand (TTU) issues can vary a lot depending on their nature. NQMSfiber takes that down to a few minutes.

A flood of alarms on a particular link at a given moment usually means that a cable was damaged. Despite the obvious, it can still take hours before the damaged section can be located and repaired. NQMSfiber not only automates fault localization but helps to identify progressive or intermittent issues gradually impacting more and more fibers on a specific cable route, in which case it is less obvious to identify the problem's root cause or locate it.

Typical situations with lengthy TTU:

  • Rodents attacking a few fiber strands and cable areas
  • Fires consuming a cable gradually
  • Cable moved and bent during construction works
  • Degrading splices due to humidity or water in enclosures
  • Icing and de-icing due to temperature variations
  • Exposure to extreme heat
  • Bends created during intervention in a fiber management tray or splice enclosure
  • Disconnecting the wrong port when servicing an area

The fact that NQMSfiber can integrate the external fiber inventory with GIS-related information (in most cases), allows OTDR data and the physical path to be viewed top-down on the same distance scale. This allows for rapid fixes and greatly simplifies inventory management.

Connecting and integrating physical network inventory and GIS data is critical as any measurement taken with an OTDR can be afterwards traced to the fiber documentation from the ODF port where the measurement was taken to the point of failure. NQMSfiber can automate the triggering of this tracing function by calling an external GIS using an http type call such that a GPS point and related information can be obtained in response.

NQMSfiber provides a standard SOAP/XML API in order to integrate and leverage existing cable and fiber management tools and GIS platforms without the need to duplicate and manually import or migrate these data to the monitoring platform. The GIS server must have key functions available in order to integrate, among which a daily or on-demand update of the data set so that any changes done in the field during provisioning, re-routing or maintenance activities are becoming visible to the monitoring platform.

PNI/GIS solution available with NQMSfiber

NQMSfiber can be purchased and installed with a physical network inventory/GIS tool for fault-on-map called OSPinsight. This integrated solution addresses both the optical fiber documentation challenge as well as the 24/7 fiber monitoring providing comprehensive optical fiber network management from planning to support and maintenance.

Unique test method for automated baselining process

NQMSfiber uses statistical learning for its baselining process. In the learning phase, NQMSfiber monitors each section, event loss and reflectance. It then gradually narrows the applied thresholds down to the target threshold, or if not possible, down to a level few times the standard deviation measured during the process. The process validates if the user's target threshold set is achievable- if not, it automatically sets them to optimal values. These depend on the OTDR parameters, the measured link loss and reflectance stability.

Comprehensive alarming and alerting functions

NQMSfiber can notify you in various ways. It can be configured to send notifications by email, as a text message, an http post or an SNMP trap. Alerts can be set by level of priority, by alarm type, by region, and by type of event (i.e., pending, acknowledged, resolved). NQMSfiber supports an alarm API (xml/SOAP) which allows a Fault Management System to reconciliate system opened alarms with an external list.
