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.
