Claims

[Scope of utility model registration request]

(1) An optical fiber is formed from a central core and a cladding around the core, a part of the cladding is removed to expose a part of the core, and the exposed part of the core is 1. An optical fiber optical switch characterized in that an off-side switch body having a higher refractive index than a refractive index and an on-side switch body having a lower refractive index are alternately arranged so as to be able to be freely moved toward and away from the refractive index.

(2) An optical fiber characterized in that the off-side switch body is either a liquid or ferromagnetic particles mixed in the liquid and moved in the liquid by magnetic force, and the other is the on-side switch body. light switch.
