Fiber optical preform rod is the core raw materials of manufacturing quartz series fiber. Simply the special prefabricated big stick of glass used to pull fiber (silk).

People in the manufacture of optical fiber system must first make optical fiber preform rod, preform rod general diameter of a few millimeters to tens millimeters (commonly known as light bar). The internal structure of the optical fiber is formed in the preform rod, and thus the production of the preform rod is the most important part of the fiber process.
