The NK7000 Optical Cable Identifier is a high-performance fiber identification instrument designed for safe and accurate live fiber detection. Based on elastic light modulation technology, it converts fiber bending signals into audio and visual alerts for precise identification. With integrated OTDR, OPM, LS, VFL, Event Map, and Loss Test functions, it provides a complete solution for cable tracing, maintenance, and emergency field operations.
