NV6418 PON OTDR

Product Summaries:
NV6418 OTDR is a high performance measuring instrument with multifunction 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.

Extra-short event dead zone
    Due to its high resolution, NV6418 OTDR has 1m extra-short event dead zone, which is suitable for testing short optical fiber and pigtail optical fiber.

High-speed auto analyze
    NV6418 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 NV6418 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.

Unique PON testing capability
    NV6418 is ideal for access and FTTH network testing, it enable you to test through 1x32 even 1x64 splitters for PON(passive optical network) testing.
    NV6418 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 built-in 650nm visual fault locator (VFL) is ideal for identifying bad splice, bad connector, break or macro bend easily. The standard VFL with more than 2 mill watt output powers is factory installed in NV6418, which the operation distance is in excess of 5 kilometers.
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 NV6418 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.
Multiple Wavelengths and Models
    NV6418 OTDR 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 NV6418 can be used widely from long range to FTTx, CATV, LAN, Access and Metro networks.
Abundant external interface
    NV6418 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
 4. Updating application software on-line

NV6418 OTDR is mainly used to measure FTTx network, it provides multifunction 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.
