A light launch device for transmitting light into a traceable fiber optic cable assembly with tracing optical fibers is disclosed herein. The traceable fiber optic cable assembly and light launch device provide easy tracing of the traceable fiber optic cable assembly using fiber optic tracing signal
A light launch device for transmitting light into a traceable fiber optic cable assembly with tracing optical fibers is disclosed herein. The traceable fiber optic cable assembly and light launch device provide easy tracing of the traceable fiber optic cable assembly using fiber optic tracing signals. Further, the launch connector is easily attached to and removed from the fiber optic connector with repeatable and reliable alignment of optic fibers, even when the fiber optic connector is mechanically and/or optically engaged with a network component. The fiber optic connectors are configured to efficiently illuminate an exterior of the connector for effective visibility for a user to quickly locate the fiber optic connector.
