A fiber-to-fiber coupler (FFC) from Coherent enables the use of replaceable process fiber optic cables, protecting integral components of the fiber laser, including the feeding fiber, from opto-mechanical damage in harsh industrial processes, which can cause downtime. It enables the use of a separate fiber interface, which can be exchanged in minutes when damaged. The FFC is an eye-safe, stand-alone, water-cooled photonic component that handles 12 kW of laser power and can couple fibers of different core diameters, as well as commonly used connector interfaces (QB, QD and Q5). It incorporates DGUV-certified safety electronics, and is an extension of the feeding fiber interlock circuit. It also includes integrated sensors, monitored and controlled by CANopen communication, with threshold values which can enable or disable the interlock circuitry.
