Optical Fiber Preform Market: Consumption and Applications Analysis Forecast by 2017-2022

Global Optical Fiber Preform Market is segmented, By End User Industry into Telecom Industry, Power Industry, Petroleum Industry, Submarine Cable, Other. Standard optical fibers are made by first building a large-diameter "preform" with a carefully controlled refractive index profile, and then "pulling" the preform for forming the long, thin optical fiber. The preform is generally made by 3 chemical vapor deposition methods; viz vapor axial deposition, outside vapor deposition, and inside vapor deposition.

With inside vapor deposition, the preform starts as a hollow glass tube approximately 40 centimeters (16 in) long, which is placed horizontally and rotated gradually on a lathe. Gases such as germanium tetrachloride (GeCl4) or silicon tetrachloride (SiCl4) are injected with oxygen at the end of the tube. The gases are then heated by means of an outside hydrogen burner, thereby bringing the temperature of the gas up to 1,900 K (1,600 °C, 3,000 °F), where the tetrachloride’s react with oxygen for producing produce silica or Germania (germanium dioxide) particles in the optical fiber perform industry.

In vapor axial or outside vapor deposition, the glass is formed by flame hydrolysis, a reaction wherein germanium tetrachloride and silicon tetrachloride are oxidized by reaction with water (H2O) in an oxyhydrogen flame. In outside vapor deposition, the glass is deposited onto a solid rod, which is removed before additional dispensation. In vapor axial deposition, a short seed rod is used, and a porous preform, whose length is not limited by the size of the source rod, is built up on its end. The porous preform is consolidated into a solid, transparent preform by heating to about 1,800 K (1,500 °C, 2,800 °F).

Typical communications fiber makes use of a circular preform. For certain applications such as double-clad fibers, the other form is preferred. Herein, an asymmetric shape improves the filling factor for laser pumping in the Optical Fiber Preform Market.However, careful polishing of the preform is important, since any defects of the preform superficial affect the optical and mechanical possessions of the subsequent fiber. In particular, the preform for the test-fiber shown in the figure was not polished well, and cracks are seen with the confocal optical microscope.
