    Abstract: An improved method of preparing optical fiber preforms and optical fibers by so called rod-in-tube method, wherein before collapsing a tube to heat-adhere to a rod, a specific glass surface treating agent and oxygen gas are flowed through the clearance between the rod and the tube maintained at a high temperature, whereby an optical fiber preform free from imperfections at the interface between the rod and the tube can be produced so as to give optical fibers of low-loss. As the above glass surface treating agent, those materials are employed which satisfy the following criteria: (i) the hydrogen content thereof being not more than about 1% by weight, and (ii) the substances, produced therefrom in the presence of oxygen gas at a high temperature, having a boiling point or sublimation point of not more than the temperature required for collapsing the tube.

    Abstract: According to one embodiment a method of making optical fibers comprises: (i) manufacturing a core cane; (ii) situating a plurality of microstructures selected from rods, air filled tubes and glass filed tubes and placing said microstructures adjacent to the core cane, said microstructures forming no more than 3 layers; (iii) placing the core cane with said adjacent microstructures inside a holding clad tube; and (iv) placing interstitial cladding rods inside the holding (clad) tube, thereby forming an assembly comprising a tube containing a core cane, a plurality of microstructures and interstitial cladding rods. The assembly is then drawn into a microstructured cane and an optical fiber is drawn from the microstructured cane. According to several embodiments, the method of making an optical fiber includes providing at least one air hole and at least one stress rod adjacent to the core.
