Optical Time Domain Reflectometer

AV6416 handheld optical time domain reflectometer is a fiber optic test equipment specially designed for FTTx. It is mainly used to measure physical characteristics including length of fibers and cables, transmission loss and connection loss. Moreover, the optical time domain reflectometer is able to pinpoint event points and fault points in fiber links. The TDR equipment is widely used for engineering construction, line maintenance and emergency repair in optical fiber communication systems as well as developing and production testing of fibers and cables.

Major Features of the Optical Time Domain Reflectometer
1. Handheld, light weight and ease of carrying
2. The handheld OTDR is produced by the world most advanced splash proof molding technology of integration of double color and double material. It is sturdy and durable. 
3. Advanced anti-reflective LCD ensures clear display of operation interface even in the open air.
4. 1.6m super short dead event zone allows for flexible test of optical patch cords.
5. The OTDR tester comes with both manual and automatic test functions
6. With two USB interface forms, the optical time domain reflectometer can be connected to a external USB and communicate with a PC by ActiveSync software
7. Supporting Bellcore GR196 file format
8. Intelligent battery remaining capacity indicator and low battery warning function
9. WinCE operating system and operating interface in English and Chinese
10. 10 hours super long batter life makes the fiber optic tester ideal for outdoor construction.
11. VFL function (visual fault location function)
12. Optical output port of the OTDR equipment is replaceable, ensuring clean end face and convenient operation.
13. With a more humanized deign, the optical time domain reflectometer comes with comfortable straps to make it easy for operating workers to carry.

Short Event Dead Zone
With an extremely short event dead zone, AV6416 fibre optic tester is especially suitable for testing of ultra short optical links and optical patch cords.

Fast Curve Analysis
AV6416 time domain reflectometer can quickly and accurately pinpoint event points or fault points and related location information in the test curve. In the meantime, it lists all event information in the form of an event list. The curve analysis feature is very helpful for line maintenance workers to improve work efficiency even when they don't know very well about the relevant background knowledge of the instrument which is difficult to understand.

Powerful Document Management
AV6416 optical time domain reflectometer has a powerful function of document management. In addition to storage, browse and delete of files inside of the machine or a USB flash disk, it also can be connected to an external PCL language-based laser printer or ink-jet printer, thus printing test report conveniently. Moreover, AV6416 achieves high speed communication with a PC through a USB date line with the help of ActiveSync software.

Convenient VFL Function
VFL function enables AV6416 optical time domain reflectometer to find out breakpoints or points with large loss in short optical links. Hence, maintenance workers can take timely actions to save a lot of time.

Automatic Detection of Optical Signals And Warning
When OTDR tests optical links, the accuracy of test results will be deteriorated and even the optical detector will be damaged permanently if communication optical signals are present in the fiber. AV6416 time domain reflectometer can automatically detect the communication optical signals in the fiber. Once connected to the optical interface, AV6416 will begin to check if there is any communication optical signal in the fiber. If there is, AV6416 will generate a warning signal to ensure the most quick and timely protection to the instrument.

Manual Test Mode
Manual test mode is suitable for skilled operators, who know the optical time domain reflectometer very well, to get more accurate test results. In this testing mode, users can choose average or real time test pattern as required. The real time test can detect dynamic changes of optical links and is often used to monitor or observe connection process and connecting efficiency of optical links.

The average test mode is applied to test optical links in a stable state. It can suppress noises in the test curve to the greatest extent to get more accurate test results. The average number has an impact on noise suppression effect. The larger the average number, the better the effect of noise suppression but the longer the test time. Hence, the average number needs to be set in practical use.

Dead Zone Test Mode
Dead zone test mode is suitable for testing of ultra short optical fibers, such as testing the length of optical patch cords. In this mode, reflection loss (or return loss) of the end of the fiber measured should be larger than 40dB if users hope to get the best test results.

Fast Automatic Test
Besides manual test mode and dead zone test mode, automatic test mode is also available which is cost-efficient as well. Automatic test function leads to very simple test procedures. Without need to learn more about the operation details, users just have to connect the fiber and click the test button. Then the optical time domain reflectometer will automatically set optimum test conditions and generate accurate testing results including test curve and event list.
