Fiber to Fiber Coupler

The Fiber to Fiber Coupler (FFC) makes it possible to couple a laser beam from one fiber optic cable to another. It is built as an eye-safe stand-alone unit with one fiber input and one fiber output. The water-cooled FFC is designed to handle high power levels (up to 12 kW) and is stable over time. Losses in beam quality and power are minimized. The FFC process is controlled by DGUV-certified safety electronics within the electronics fin. The electronics also includes integrated sensors monitored and controlled by CANopen communication.
