Patent ID: 11934016
Assignee: SHODEN SEIWA CO., LTD.
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 4:
5. A method for checking a bending radius of an optical cable that is connected to the optical adapter holding structure according to claim 1, the method comprising:
acquiring in advance a swaying starting moment of the swaying mechanism;
acquiring in advance a relationship between a moment applied to each of the optical adapters and a bending radius of the optical cable at the time of applying a force to the optical cable connected to each of the optical adapters;
making sure that the moment applied to each of the optical adapters is equal to or less than the swaying starting moment by checking that all the optical adapters are not swaying and are kept in a normal state; and
knowing that the bending radius of the optical cable is equal to or more than a certain radius since the moment applied to each of the optical adapters is equal to or less than a certain moment.
