The OFL100 OTDR enables the front-line fiber technician to quickly locate loss events in the last mile of the FTTx network.

The convenient touchscreen provides an intuitive interface making it simple for even newly provisioned technicians to locate loss events such as cut fibers, contaminated or damaged connectors, and excessively bent fibers.

reflectometre OTDR

The Auto Mode allows the technician to initiate a measurement without adjusting any test parameters. The Expert OTDR Mode provides access to all features the savvy OTDR technician demands so they can refine measurement parameters enabling them to troubleshoot the most demanding faults. The OFL100 includes an integrated visual fault locator (VFL), stabilized light source (SLS), and optical power meter (OPM).

Results can be displayed using a traditional OTDR trace or linear map with user selectable Pass/Fail analysis. All events are measured, annotated, saved, and exported as an industry standard SOR file that is compliant to GR196 Telcordia standards. The SOR file can be imported into the Trace Viewing program where analysis can be performed, and test results can be saved as a PDF report.
