1. An optical fiber processing apparatus for forming light output windows in an optical fiber having a core and a clad surrounding the core, comprising:
an optical fiber machining head including a head core with an optical fiber proceeding tunnel through which the optical fiber passes, a head body supporting the head core, a coolant passing hole formed in the head body and fluidly connected to the proceeding tunnel of the head core, and a plurality of processing rod insertion holes provided in the head body for optical fiber processing formed in the circumference of the tunnel;
a plurality of rotational processing rods, each having a machining tip configured to form cutting areas in the clad of the optical fiber to form the light output windows around the core of the optical fiber thereby exposing the surface of the core at a bottom of the light output windows, in the proceeding tunnel through the processing rod insertion hole; and
a plurality of actuators, each configured to reciprocate and rotate the respective processing rod having the machining tip to thereby form the cutting areas as the light output windows.
