Fibre-optical device and method with intensified resitance to environment condition

Abstract

A method for producing fiber optic devices having improved intrinsic resistance to external environmental conditions and a fiber optic device made my the method are disclosed. The fabrication method produces an optic device that is treated with deuterium. The method includes a step for treating and / or making optical devices in the presence of a flame produced by the combustion of deuterium gas or a mixture including deuterium.

Description

related application This application is a continuation-in-part of U.S. Patent Application Serial No. 10 / 160,165, filed June 4, 2002, which is hereby incorporated by reference in its entirety. technical field The present invention relates to the fabrication of fiber optic devices, and more particularly to a method of fabricating fiber optic devices having enhanced inherent resistance to external environmental conditions. Background technique The extensive and global use of fiber optic networks and systems requires that fiber optic devices and components be able to operate reliably over a long period of time, which imposes stringent performance requirements on the various fiber optic devices and components used in the networks and systems. In this regard, because fiber optic equipment and components are expected to operate reliably for decades or more, the components typically pass a series of mechanical and environmental tests to check their long-term stability before bei...

However, these attempts also failed with

These methods are imperfect as it has now been found that the introduction of water and water-related substances in production is not the main cause of long-term drift in optical properties in DHA environments
