TW432235B - Method of making optical fibers - Google Patents

Abstract

An optical fiber having optical characteristics that vary along its length is made by assembling a plurality of cylindrical glass or soot tablets into or along a glass tablet alignment device, then fused into monolithic assembly. If desired, additional glass may be applied to the assembly before or after the fusing step. A vacuum is preferably applied during the fusing step. Each tablet preferably contains a core region, and it optionally contains a layer of cladding glass. Adjacent tablets are capable of forming optical fiber sections having different optical properties. Prior to consolidating the glass particles, chlorine preferably flows through or around the tablets and alignment device. The resultant draw blank can be drawn into a low loss optical fiber having short transition regions between adjacent areas of fiber. This method is particularly useful for making dispersion managed single-mode optical fibers.

Description of the new type: [Technical field to which the new type belongs] This case relates to a sliding structure, especially a sliding structure that can slide a top cover relatively smoothly without being stuck when sliding relative to a base. [Previous Technology] A tablet PC (Tablet PC) is a small, portable personal computer that uses a touch screen as a basic input device. Therefore, users can use the built-in handwriting recognition, the virtual keyboard on the touch screen, and voice recognition to perform input operations instead of using a traditional keyboard or mouse. So basically, a tablet is a full-featured personal computer without a flip cover, no keyboard, and small enough to fit in a handbag. Because the tablet computer does not have a physical keyboard, so for the user who is used to typing with a physical keyboard, the handwriting recognition or virtual keyboard provided by the touch screen does not meet the needs of fast and accurate typing. Based on the aforementioned tablet computer has no physical keyboard Defects in the keyboard settings, the related industry tried to combine the base of the tablet computer with a solid keyboard as a body, and on the bottom surface of the tablet computer and the top surface of the base _ set with a pair of symmetrical slide structure, each slide At the end of the rail structure, the button connecting the wire seat ||.
