that keeps up with the times and carries intelligence. With
the advancement of optical technology, the application of optical
fiber today is no longer limited to the transmission of waveguide
communication. Rather, it focuses on the broader utilization of
two characteristics namely optical wavelength and photon. Thus,
fiber technology is like a beautiful tree that is ready to bloom and
yield full fruits.
If optical fiber and its application are those flowers and fruits,
the optical fiber preform technology, is the trunk of such a big
tree where flowers and fruits are grown. The further evolvement
of optical technology, together with special optical preform
technology and communication fiber preform technology will distance and low waste OAM fiber preform can be achieved.

of perceptual data and demands for efficient transmission,
intelligence process will inevitably count on optical sensing
