As a preferred embodiment of the invention, the diameter of the core insert of the optical fiber is 0.2mm, and the diameter of the core layer of the optical fiber is 0.061mm.
In the specific embodiment of the invention, the optical cable works on the principle that energy and signals are transmitted by utilizing the theory that light can be totally reflected in an optical fiber.
