The Perfect Handheld Tester Series
OTDR TW2000
Description
TW2000 palm OTDR is the newest instrument designed for testing FTTx network. It's mainly used to measure the physical characteristics of optical fiber under test, such as the length,the transmission loss and the splice loss etc.. It can also locate the faults or breaks of optical fiber. It's widely applied in the manufacture, construction and maintenance in optical fiber communication system.
TW2000 palm OTDR has the most advanced technology of double-color & material integrative mould, which is novel and beautiful in appearance.TW2000 offers three wavelengths and VLF in one handheld unit, especially for testing passive optical network (PON) in FTTx. In addition, it's equipped with comfortable gallus for carrying conveniently.

♦ Visible fault locating (VFL)
♦ Universal FC/PC,FC/SC,FC/ST connector type, it's convenient for surface cleaning
♦ Unique function of updating system on-line, returning to factory is unnecessary
♦ Extra-short Event Dead Zone
TW2000 palm OTDR has extra-short event dead zone, which is suitable for testing short optical fiber and pigtail optical fiber.
♦ High-Speed Auto Measurement
The function of auto measurement of TW2000 palm OTDR makes it unnecessary to operator to know about the further details of operating. Simply connect the fiber, press [Start],then the result is displayed in a few seconds, you can view the trace and event table.
♦ High-Speed Auto Analyzation
TW2000 can search and locate the events and faults in trace rapidly and precisely, and then lists all events in even table, so it's very useful to maintainers to improving efficiency and it's unnecessary to know about the relative background knowledge.
♦ Strong File Management
TW2000 offers powerful function of file management. Besides saving,browsing or deleting files to or from USB stick and built-in memory, it can be connected to laser or inkjet printer based on PCL language, and the testing report can be printed rapidly and easily. In addition, TW2000 can communicate with PC using ActiveSync via USB cable, through which the files can be translated rapidly.
♦ Convenient VFL
The built-in 650nm visual fault location is ideal for easily identifying bad splice, bad connector, break or macro bend.
♦ Application:
TW2000 Palm OTDR is mainly used to measure FTTx network, it provides a low cost solution for users.TW2000 offers three measuring modes: manual mode (including real time mode and average mode), auto mode and dead zone mode.
Manual measurement mode: manual mode is suitable for skilled operator who is familiar with the instrument. In this measurement mode, to get more accurate results, real-time mode or average mode can be selected if necessary. In real-time mode, the dynamic changes of fiber chain can be detected timely, it is very useful when you need to watch the effect and process of fiber being spliced or connected.
In average measurement mode, the noise in trace can be suppressed, and the SNR(signal noise ratio) is improved, therefore,the result is more accurate. In fact, the more average times is executed, the more noise in trace is suppressed, and the longer time is spent for signal processing. In practice, the average times should be set properly according to necessity.
Auto measurement mode: the optimized measurement conditions are set automatically, it's unnecessary to operator to know about the complicated background knowledge and the further details of operating. In this mode, the more accurate results can be gained when proper average times are set, but it will increase the time of signal processing.
Dead zone mode: this mode is suitable for testing optical fiber with short distance and the optimized settings of distance range, pulse width and attenuator can be executed automatically. To get the best result, the terminal return loss should be guaranteed less than -40dB.
