The Corning Cable Systems MiniDK OV-Mini Optical Time Domain Reflectometer (OTDR) provides a rugged, handheld and lightweight solution for testing and troubleshooting fiber optic networks. This handheld OTDR gives the operator the flexibility of testing single-mode and 50 and 62.5 µm multimode systems with the same unit. The OV-Mini provides complete connectivity flexibility (with USB stick compatability and USB cable download) and top user-friendliness (offering one-touch testing). A power meter, Visual Fault Locator (VFL) and video inspection software is included. The OV-Mini utilizes Windows® CE technology allowing for a faster power-up time of four seconds from sleep mode.The OV-Mini has a large internal memory that typically stores up to 500 traces and eliminates the need for a hard drive, which can fail under extreme field conditions.
