High-speed auto analyzation

AV6418 can quickly determine and locate the events and faults in trace precisely, 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.

High-speed auto measurement

The function of auto measurement of AV6418 Optical Time Domain Reflectometer 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.

Unique PON testing capability

AV6418 is ideal for access and FTTH network testing, it enable you to test through 1x32 even 1x64 splitters for PON(passive optical network) testing. It 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.

Convenient VFL function

The standard VFL with more than 2 milliwatt output power is factory installed in AV6418, which the operation distance is in excess of 5 kilometers.

Communication Light Check

When measuring a fiber in service, the measuring result by an Optical Time Domain Reflectometer is not precise, and there is a potential risk of permanent damage to the internal photoelectric of Optical Time Domain Reflectometer receiver. To prevent these problems, it 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 Optical Time Domain Reflectometer protection will be active instantly.

Multiple Wavelengths and Models

AV6418 Optical Time Domain Reflectometer can provide any of single mode or multimode or both, designed to test FUT at up to four wavelengths in single unit, such as 850, 1300, 1310, 1383, 1490, 1550, 1625 and 1650nm wavelengths, with which AV6418 can be used widely from long range to FTTx, CATV, LAN, Access and Metro networks.

Abundant external interface

AV6418 has abundant external interface, such as USB, Min-USB, Ethernet, earphone and SD, due to these, it can provide the following functions:

1. Training via multimedia for operators, which can enable you become a measuring expert within short time.

2. Implementing remote controlling through Ethernet, troubleshooting from long distance for fiber under test.

3. Printing trace and event table

Typical application:

AV6418 Optical Time Domain Reflectometer 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), dead zone mode.

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.

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.
