The Fluke FOM Fiber Optic Meter is a versatile tool designed to simplify the testing and maintenance of fiber optic cable systems. By connecting directly to a DMM with a mV DC function and a 10 MΩ input impedance, users can quickly and accurately verify fiber optic cable system loss. This eliminates the need for a complete new meter, making it a cost-effective solution for technicians and engineers. Light sources and patch cords are required and sold separately.
