1. A management system for managing an upper free-space optical communication apparatus and a lower free-space optical communication apparatus that carry out free-space optical communication in an up-and-down direction, the management system comprising:
at least one processor,
the at least one processor carrying out:
an acquisition process of acquiring a first index that indicates a quality of a first upward light signal received by the upper free-space optical communication apparatus; and
a determination process of determining, in accordance with the first index, a possibility of contamination of a light sending and receiving window of the lower free-space optical communication apparatus,
the lower free-space optical communication apparatus being configured to send and receive a light signal of the free-space optical communication through the light sending and receiving window.
 
7. A management apparatus for managing an upper free-space optical communication apparatus and a lower free-space optical communication apparatus that carry out free-space optical communication in an up-and-down direction, the management apparatus comprising
at least one processor,
the at least one processor carrying out:
an acquisition process of acquiring a first index that indicates a quality of a first upward light signal received by the upper free-space optical communication apparatus; and
a determination process of determining, in accordance with the first index, a possibility of contamination of a light sending and receiving window of the lower free-space optical communication apparatus,
the lower free-space optical communication apparatus being configured to send and receive a light signal of the free-space optical communication through the light sending and receiving window.
 
13. A management method for managing an upper free-space optical communication apparatus and a lower free-space optical communication apparatus that carry out free-space optical communication in an up-and-down direction, the management method comprising:
acquiring a first index that indicates a quality of a first upward light signal received by the upper free-space optical communication apparatus; and
determining, in accordance with the first index, a possibility of contamination of a light sending and receiving window of the lower free-space optical communication apparatus,
the lower free-space optical communication apparatus being configured to send and receive a light signal of the free-space optical communication through the light sending and receiving window.
