Overview
VT-42FR Min mini optical time domain reflectometer is compact and easy to carry; it adopts a 3.5-inch high-definition touch screen, supports multi-touch and smooth operation. Internal integration of OTDR, optical power, red light, flashlight and other functions in one, to meet various test needs in different occasions. Among them, the OTDR function adopts 1550nm wavelength and built-in high-efficiency wavelength isolator. It can perform optical test on 1490nm and 1577nm links. It supports optical live test capability, and the maximum measurement range is 60km.
VT-42FR Min is used to measure the length, loss, connection quality and other parameters of the optical fiber. It can easily test the breakpoint, bend, and loss point of the optical fiber link. It is suitable for line maintenance and emergency repair testing by installation and maintenance personnel
