Fiber Network Monitoring and Management Solutions


OTDRs are commonly known to network operators as portable units, but EXFO also integrates them in rack-mount equipment along with optical switch and controller units. These are used to perform on-demand troubleshooting of any fiber connecting to the equipment, whether it transports live traffic or not, and whether it is connected permanently or temporarily. Routine maintenance tests can therefore be scheduled and automated to dramatically simplify this process. 

Optical Fiber Maintenance at a Lower Cost

EXFO offers various optical testing instruments and system configurations to help you reduce support- and maintenance-related expenses. Here are some of the available configurations and options: 

  • Dark fiber testing and monitoring for any fiber cable network
  • In-service, in-band CWDM testing and monitoring
  • In-service, out-of-band 1625 nm or 1650 nm testing and monitoring
  • Stand-alone, fully autonomous test equipment
  • External 1 x n optical switch (up to 128 ports)
  • Double-stage m x n test port (expansion capabilities)
  • Remotely controlled optical switch unit
  • Distributed client-server application with central management
  • Reporting engine based on alarm duration and fiber downtime
  • Network documentation on GIS platform with fault-on-map
  • Water/humidity sensors to be  located into splice enclosures
  • Integration with fault or work ticket management system(s)
  • Integration with network inventory/GIS solution
  • Integration with BSS/OSS in general

With an OTDR set in one location, shared among your technical staff and also accessible through other systems, you can change the way you support your network and your customers. Web access is standard on all EXFO platforms; from any location and from any computer linked to a VPN in your corporate network. You are therefore able to perform OTDR testing or define and start a preventive test cycle to identify recurrent issues on your fiber network.

In addition to boosting the efficiency of your technical workforce, you can speed up link failure root-cause analysis and save two to five hours per event, therefore accelerating time-to-repair with better-quality information about the nature and location of the reported fiber/cable fault.

Other benefits and applications include:

  • Notification of fiber/cable outages—big or small—within minutes through e-mail or SMS
  • Correlation of network alarms generated from any application or equipment and rooted to the optical layer
  • Faster dispatching of repair teams to the exact location
  • MTTR and fiber availability measurement, and higher KPIs
  • Faster impact analysis with proper inventory of service relations
  • Pre-activation test of a new link or before switching traffic to an “unknown” fiber route
  • Continuously updated inventory as the OTDR explores your network
  • Better field staff support through remote testing, e.g., after restoration is complete
  • Up-to-date health status for specific regions or the entire network
  • Assessment of your network’s aging process through yearly measurement comparisons
