The NT7310 series OTDR adopts a 7-inch capacitive touch screen and integrates nine modules. With an excellent hardware and software design the accuracy of short-fibre testing and the level of automatic testing are both higher; the instrument is equipped with rich Ethernet testing (Ping/PPPoE and more) and supports APP control. The series is used to test optical fibre length, loss and connection quality, and in engineering construction and link maintenance testing, mainly in urban trunk, bone trunk and metropolitan area networks.
