Optical cable for transmission of data has transmitter at one end and receiver at other end and movable sensor device between two ends

摘要

The optical cable or waveguide (1) is made of a light-conducting medium whose optical characteristics may be influenced by an external electromagnetic field. A probe (4) may be displaced (5) along the length of the waveguide and may use electromagnetic fields to modulate optical signals passed along the waveguide from the transmitter (2) to the receiver (3).
