Product Description

Product Overview
OTDR This exceptional device is capable of testing a diverse range of single-mode wavelengths, including 1310nm, 1550nm, 1490nm, 1625nm, and 1650nm, as well as multi-mode wavelengths of 850nm and 1300nm. This flexibility extends to customized special wavelengths, ensuring comprehensive coverage. With the provision of multiple optional modules - such as single wavelength, multi-wavelength, and online test - this instrument is equipped to handle varied testing scenarios. Boasting a maximum dynamic range of up to 50dB, it is perfectly suited for testing remote multi-branch communication networks. Designed with a minimum event dead zone of just 0.5m, it facilitates easy supervision of near connections, while its lowest sampling resolution of 2.5cm guarantees precise event point location. The device is further engineered with an array of convenient functional options, including a stable light source, optical power meter, visible red light source, and a fiber end face inspection tester, enhancing its versatility.
OTDR is meticulously designed to operate under a temperature range of -10ºC~50ºC and a storage temperature range of -40ºC~70ºC respectively. It conforms to EMC requirements and passes rigorous vibration and shock tests, featuring an MTBF₀of 6000 hours or more to assure high reliability. The device is powered by a robust 75W built-in Li battery, providing sustained performance for continuous measurement in challenging field environments.

Rapid automatic test functionality
Thanks to the automatic test function of OTDR, users are liberated from the need for extensive operational knowledge. Simply connect the optical fiber and press the [Test] button. The device will autonomously determine the optimal testing conditions and deliver precise results, including test curves and event lists.
Exclusive PON network test feature
As an exemplary tester for ODN and FTTx, OTDR offers a distinctive built-in PON network test capability. It can penetrate optical splitters up to a ratio of 1:128, ensuring accurate testing of each PON network branch.
Automatic detection and alarm for incoming optical signals
During testing, any optical communication signal present in the optical fiber can lead to inaccuracies or even permanent damage to the device's detectors. OTDR is capable of autonomously monitoring such signals in the fiber under test. Simply connect the fiber to OTDRThis innovative device is equipped with an intelligent automatic sensing and monitoring system that detects the presence of optical communication signals. Upon identifying a signal, it promptly triggers an alarm to ensure immediate and optimal protection for the device, offering peace of mind and reliability.
