The TEKCN TC-350 Mini OTDR is a remarkable 9-in-1 fibre testing instrument combining an OTDR, optical power meter, visual fault locator, light source, event map, fibre identifier, loss test set, talk set, and optical return loss meter in a single handheld unit — replacing an entire bag of testing equipment for field technicians. Its compact, pocket-sized design with a colour touchscreen makes it the most versatile and travel-friendly fibre test tool for contractors working across multiple sites. Suitable for testing single-mode FTTH, FTTx, and LAN fibre installations, it provides rapid fault location, loss measurement, and splice quality verification in one workflow.
