Answer 1

Explanation:

Chemical Vapour Deposition

Answer 2

Answer:

There is a wide range of methods for the fabrication of optical fibers. In a first step, these can be divided into methods involving a so-called preform and methods of direct fiber production. Preform-based methods are most important at least in the context of glass fibers, whereas direct methods, e.g. based on extrusion, are common for plastic optical fibers. In the following, this article first discusses how a fiber can be made from a preform, then how preforms are fabricated, and finally methods not requiring a preform.
