Quartz rods are processed from quartz glass and have unique characteristics and 

advantages. They can be used for single end halogen lamp bridge rod, optical fiber 

lighting, quartz fiber manufacturing, semiconductor wafer processing, etc. 

High purity fused quartz rods usually have three uses in optical fiber production: as fiber guide 

core. Its main characteristic is the low absorption rate of light in the specific band. The fiber is 

either pure quartz core (PCS) with a plastic cladding or fused quartz cladding with a lower 

refractive index. Quartz rod can be used to produce photonic crystal fiber (PCF) prefabricated 

rods (stacking different glass sheets or drilling holes in the rods) . Quartz rods can be used to 

adjust the pressure or refractive index of the local fiber. Using two stress - induced boron - 

doped rods is one of the methods to produce polarization-maintaining fiber.
