Product Description

OVERVIEW OF INTRUSMENT
The handheld optical time domain reflectometer (OTDR) is a new generation of intelligent optical measuring instrument designed for the optical fiber communication system testing .This product is mainly used to measure the parameters of optical fibers and cables, such as length, loss, and connection quality, etc.; it can realize the accurate positioning of event points and fault points, and can be widely used in the construction, maintenance testing and emergency repair of the optical fiber communication systems as well as the research, production and production measurement of optical fibers and cables and so on. This product can provide you with the highest performance of solutions for installation and construction of fiber optic network construction and the subsequent fast and efficient maintenance and troubleshooting testing.  
it has novel appearance, durable; it has the simplest interface and intuitive operation in the OTDR industry; among the same type of handheld products, its unique dual operation mode of key plus touch screen can greatly simplify the user's application; with one-key analysis, it can quickly obtain the test results. The events are displayed in the main interface in a way of list, and such information includes event number, type, event location (distance), loss, reflection, event point attenuation, total loss, etc..; the whole machine adopts the intelligent power management mode; the high capacity of lithium battery can make the whole machine working for more than 10 hours, so it is very suitable for outdoor environments for a long time.
