Product Overview

The NK3200 is a professional mini handheld optical time-domain reflectometer (OTDR), specially designed for fiber optic link testing, fault location, construction acceptance and daily maintenance. It adopts advanced optical detection technology, utilizing Rayleigh scattering and Fresnel reflection characteristics of fiber transmission channels to accurately measure fiber length, transmission loss, splice loss and connector loss, as well as locate fiber fault points and event points precisely. The device supports dual wavelengths (1310nm/1550nm) switching, with dynamic range up to 24dB, enabling long-distance fiber testing and clear identification of small-loss events. Equipped with a high-definition color TFT LCD display, it features intuitive operation interface, supports 4-point/5-point loss analysis method and SOR standard file format, facilitating data storage, export and analysis. The NK3200 integrates multiple practical functions including OTDR, VFL (Visual Fault Locator), OPM (Optical Power Meter), RJ45 cable testing and flashlight, realizing multi-scenario testing with one tool. With a compact and durable body, built-in large-capacity rechargeable battery and wide temperature adaptation, it is suitable for on-site operation in various complex environments such as outdoor, computer room and FTTH入户, and is an essential professional tool for telecom operators, fiber optic installers and network maintenance teams.
