Description JW3302E Multifunctional Automatic OTDR Optical Time Domain Reflectometer 7-inch Capacitive Full Touch Screen Description: - The JW3302E OTDR has a 7-inch capacitive full touch screen and integrates automatic OTDR, expert OTDR, event map, OPM, VFL, LS and other functions. The OTDR has a maximum dynamic range of 28dB and can achieve accurate testing up to 100km. It can achieve a minimum event dead zone of 3m and a maximum sampling resolution of 2.5cm. The OTDR is equipped with 4600mAh high density and large capacity polymer lithium battery, intelligent power saving management as well as power supply/charging by a power bank. - The JW3302E can be used to measure length, loss, connection quality and other parameters of all kinds of optical fiber and cable. It is widely used in the engineering construction, line maintenance and emergency rescue test of FTTH, MAN and secondary backbone network communication system, as well as the development and production measurement of optical fiber and cable. Features: - Max. 32/30dB dynamic range, 256k data sampling point; - Automatic monitoring function of communication light; - Support Bellcore GR196 and SR-4731file format; - Expert OTDR: Simultaneously display of expert measurement, curve, list, MAP; - Light source which supports continuous/modulated mode output; - Automatic OTDR: One-click test with no complicated setup. Quick automatic test: - Automatic testing function allows users dont need to know more details about the instrument operation which makes test steps much easier. You only need to enter the automatic test interface, connect optical fiber to corresponding OTDR port, then click on the “Test” button, the instrument will automatically set the corresponding test conditions and test results are given including test curve and event list etc. Automatic light detection and alarm function: - When OTDR tests fiber links, the test results will be inaccurate if there are communication optical signals in the fiber. It can even cause irrecoverable damage to the detector inside the instrument. JW3302E has the function of automatic monitoring of communication optical signals in the fiber under test. As long as the fiber under test is connected to optical port, it will automatically sense and monitor whether there is communication optical signals in the fiber in the test phase. Once the optical signals are detected, alarm information will be given in time to provide timely protection for the instrument.
