Double USB interfaces AV6418 OTDR 45dB High Dynamic Range

Product Overview

This product is a high performance testing instrument that is designed for testing FTTx network. AV6418 OTDR is mainly used to measure the physical characteristics of optical fiber under test, such as the length, the transmission loss and the splice loss etc.. The product can also locate the mistakes or breaks of optical fiber. AV6418 OTDR is broadely used in the manufacture, construction and maintenance in optical fiber communication system.

Main Features

1. Handheld,lightweight and convenience for carrying

2. 0.05m high distance resolution,128k sampling points

3. Fast auto measurement,one-button operating

4. Test up to four wavelengths with a single unit

5. Communication light check automatically

Extra-short event dead zone

Due to its high resolution, AV6418 OTDR has 1m extra-short event dead zone, which is suitable for testing short optical fiber and pigtail optical fiber.

Unique PON testing capability

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

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.

Communication Light Check

When measuring a fiber in service, the measuring result is not precise, and there is a potential risk of permanent damage to the internal photoelectric of OTDR receiver. To prevent these problems, the the product 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 showed and internal OTDR protection will be active instantly.

Multiple Wavelengths and Models

It provides 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 it can be applied broadely from long range to FTTx, CATV, LAN, Access and Metro networks.
