Product Description
1.Signal-to-noise ratio: 2.5 million programmable logic gate is used to collect data on average, improve the testing accuracy and testing speed
2.Collect data to improve: it adopts advanced technology with the international synchronization of 40 MHZ high-speed sampling technology
3.Wde temperature working status: it can within the scope of – 10 ℃to 45 ℃to normal test.
4.Advanced laser and APD (light detector) hardware and software protection
5.Large capacity storage (maximum storage 1000 results).
1.The real-time measurement both convenient and practical
FL Series OTDR products provide the real-time measuring models, fit for massive optical fiber scanning test to get high efficiency.
2.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 tested traceagain.
3.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 damages to 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
4.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。
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.
6.The powerful OTDR 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.
The powerful batch processing function
(1)The Trace batch processing function realease user from mass repeated trace management works.
(2)Event table mainteance
Add,delete or modify any event of event table manually leading to perfect optical cable report.
