  Unique advantages

The real-time measurement both convenient and practical

GK Series OTDR products provide the real-time measuring models, fit for  massive optical fiber scanning test to get high efficiency.

Intelligent Trace Scaning

The built-in intelligent trace scaning modules can both quickly and precisely analyse the trace, listing out the necessary information in event table

including event location,fault location with friendly user interface, ,which is understandable to line maintainers especially ones without professional

educational background. If cusomers are not content with the event table , they can set the analysis parameters and reanalyze the


Online Work Light detection Functions

      The communication work light signal in the tested optical fiber not only affects the OTDR testing quality but also imposes unrecoverable

damagesto APD in the equipment.FT-100 series OTDR products can automatically test and indicate the communication work light signal in the

fiber and provide the instant and prompt protection to the equipment as soon as possible.

The friendly User Interface

The friendly user interface shows details of the event list in a clear and big screen. Coordinated with the distinctive designed keyboardoperation, 

displaying of  event trace  in a clear and brief wayfor trace zooming in or zooming out

keyboardoperationThe Convenient VLS Function

The VLS function help to quickly find out the breakpoint or big insertion loss point of near end of fiber, so that user can take actions as soon as possible to save the time.

ü The powerful OTDR (optical time-domain reflectometer) File Tool software function: trace management, trace print and trace browse.

The OTDR File Tool software based on windows system is specially designed for off-line data process.

u   The powerful batch processing function

The Trace batch processing function realease user from mass repeated trace management works.

u   Event table mainteance

Add,delete or modify any event of event table manually leading to perfect optical cable report.
