NON-INTRUSIVE MONITORING OPTICAL CONNECTION BETWEEN TWO FIBER OPTIC LINES

摘要

A non-intrusive monitoring optical connection between two fiber optic lines including a sending fiber optic end that emits light to a first lens that collimates the light to a larger diameter parallel beam of light that enters a tunnel, a second lens that focuses the light from the tunnel to an end of a receiving fiber optic line, a mirror disposed in the tunnel between the first and second lenses, which reflects and diverts part of the parallel beam of light to a diverting tunnel, and a second diverting mirror, disposed at a non-zero angle to a longitudinal axis of the diverting tunnel, which directs the beam from the diverting tunnel into a second diverting tunnel wherein it is collimated by a third lens, disposed in the second diverting tunnel, to an end of a monitoring fiber optic line.
