MONITORING OPTICAL SIGNAL ARRIVAL ADJUSTMENT DEVICE, OPTICAL COMMUNICATION TRANSMISSION PATH, OPTICAL COMMUNICATION SYSTEM, AND OPTICAL COMMUNICATION TRANSMISSION PATH MONITORING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18025873 titled 'MONITORING OPTICAL SIGNAL ARRIVAL ADJUSTMENT DEVICE, OPTICAL COMMUNICATION TRANSMISSION PATH, OPTICAL COMMUNICATION SYSTEM, AND OPTICAL COMMUNICATION TRANSMISSION PATH MONITORING METHOD

Simplified Explanation

The patent application describes a device for adjusting the arrival of monitoring optical signals.

  • The device includes three monitoring optical signal arrival adjustment units.
  • The first unit allows a signal to reach either the first or second position, but not the third position.
  • The second unit allows a signal to reach either the first or second position, but not the third position.
  • The third unit allows a signal to reach the third position, but not the first or second position.


Original Abstract Submitted

A monitoring optical signal arrival adjustment device includes a first monitoring optical signal arrival adjustment unit which allows a first monitoring optical signal transmitted to a first position on a first optical transmission path to reach the first position or a second position on a second optical transmission path, and does not allow it to reach a third position on a third optical transmission path; a second monitoring optical signal arrival adjustment unit which allows a second monitoring optical signal transmitted to the second position to reach the first position or the second position, and does not allow it to reach the third position; and a third monitoring optical signal arrival adjustment unit which allows a third monitoring optical signal transmitted to the third position to reach the third position, and does not allow it to reach the first position or the second position.
