Pro'sKit MT-7612F Multi-function Optical Time Domain Reflectometer (OTDR)

Product Overview

The Pro'sKit MT-7612F is a professional-grade multi-function OTDR designed to simplify fiber optic installation, commissioning, and troubleshooting. Combining an Optical Time Domain Reflectometer, Optical Power Meter, and Visual Fault Locator into one compact instrument, it provides comprehensive fiber testing in the field.

Its 20 dB dynamic range enables testing of fiber links up to 80 km, while the 3 m event dead zone and 8 m attenuation dead zone improve fault location accuracy. The large 3.2-inch color LCD, internal storage for 500 records, expandable memory via TF card (up to 32 GB), and rechargeable lithium battery make it an excellent solution for fiber optic technicians, telecom engineers, and network maintenance professionals. Test results can also be transferred to a PC via USB for further analysis.
