Abstract: A non-intrusive remote wireless monitoring system is described for light signals between two fiber-optic communication lines. Most of the light from a transmitting fiber (6) goes to a receiving fiber (6?) whereas part of the light is harvested from an opening in the cladding (11) of the fiber by a photo-detector (9) connected to a passive ASIC (16) and a transmitting antenna (10). The ASIC has a unique ID for efficient monitoring of the communication lines.

Abstract: A non-intrusive monitoring optical connection apparatus includes first and second fiber optic communication lines (2, 8) arranged for light to pass therebetween. The first and second fiber optic communication lines (2, 8) have first and second ferrules (4, 6) at ends thereof, respectively. An optical element (13, 25) is disposed between the fiber optic communication lines (2, 8). Most of the light passes between the fiber optic communication lines (2, 8) and a small part of the light is harvested by the optical element (13, 25) and detected by a photo detector (15, 28).
