Ultra-short event dead zone
AV6418C has ≤0.8m ultra-short event dead zone, which is especially suitable to test the short optical fiber line and optical fiber jumper. 
High-speed curve analysis
AV6418C can rapidly and accurately analyze and find the event points or fault points in the testing curve, and further list all event information in the form of event table, which is very helpful for maintenance personnel, because they can well know the information of the tested line just through the event table.
High-speed automatic test
The function of auto measurement of AV6418 OTDR makes it unnecessary to operator to know about the further details of operating. The operation becomes very simple: after connect the fiber, only press【Start】,then the trace measured is displayed and the events are listed on screen in a few seconds, now, you can view the trace and event table.
PON network test function
AV6418C is an ideal test instrument for FTTx, with special built-in PON network test function. It can conduct high-precision test on all branches of PON network through 1:8～1:64 optical divider.
AV6418 offers an exceptional 1m event dead zone and 0.05m high distance resolution, with which you can characterize all events between the transmitter and the central office's fiber distribution panel.
Visual fault locator (VFL) function
The built-in VFL function of AV6418C has 3 operating modes: CW / 1Hz / 2Hz. VFL can rapidly and conveniently find the breaking point or remarkable loss point along the short-distance optical fiber line, so that the maintenance personnel can take steps in short time.
Automatic detection & alarm on the communication light signal
When measuring a fiber line in service, if there is communication light signal in the fiber, the result will be inaccurate, and it may even cause permanent damage to the optical detector in the instrument. AV6418C is capable of automatically detecting the communication light signal in the fiber under test once the fiber is connected to the optical connector. If there is light signal, it will alarm, so that to provide protection for the instrument in time.
Multiple external interfaces
AV6418C offers multiple external interfaces as standard configuration, such as USB, Min-USB, Ethernet, earphone and SD interface, which can realize functions as follows:
- Connection with external U disk or SD card;
- Connection with external printer based on USB interface;
- Data communication with PC;
- Remote control via Ethernet;
- Connection with earphone
- Training via multimedia for operators, which can enable you become a measuring expert within short time.
- Implementing remote controlling through Ethernet, troubleshooting from long distance for fiber under test.
- Printing trace and event table
- Updating application software on-line
- AV6418 has abundant external interface, such as USB, Min-USB, Ethernet, earphone and SD, due to these, it can provide the following functions:
Communication Light Check
- When measuring a fiber in service, the measuring result by an OTDR is not precise, and there is a potential risk of permanent damage to the internal photoelectric of OTDR receiver. To prevent these problems, the AV6418 OTDR can detect automatically and silently if communication light is present after the fiber under test is connected, once the light is verified present, simultaneously, a warning message will be displayed and internal OTDR protection will be active instantly.
Typical application:
AV6418 OTDR is mainly used to measure FTTx network, it provides multifunctions in one unit. AV6418 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 observe 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.
