Sunlite OTDR

Fiber network testing simplified

The SunLite OTDR is a lightweight, handheld mini OTDR optimized for the installation and troubleshooting of FTTx, PON, CATV, Mobile Backhaul, and Metro fiber networks. Weighing less than 700g (1.54 lbs), the unit is perfectly suited to address the portability and space constraints typical of overhead CATV cable routes, curbside FTTx cabinets and manholes. Power meter, light source fiber inspection probe and VFL test options add versatility to the unit.
