Optical Time Domain Reflectometers (OTDRs) and fault locators are used to certify new fiber installations and locate faults in deployed fiber optic networks. 

OTDRs:

  • Scan and characterize fiber optic networks (from one end of the fiber).
  • Display characterized fiber either as a trace showing optical loss and reflectance vs. distance or as a LinkMap providing an icon-based representation of the fiber sections, splices, connectors and any detected faults (breaks or macro-bends).
  • Provide link summary information (end-to-end length, loss, optical return loss).
  • Provide details for each detected connector, splice or fault including event location, event type, loss and reflectance at event and loss to event.

OTDRs and fault locators are available for both multi-mode and single-mode networks including passive optical networks (PONs) supporting a range of performance requirements and budgets.
