Abstract
High-strength, low-loss splices of optical fiber can be produced by fusion splicing the fiber with a D.sub.2 -O.sub.2 flame. According to the invention, the deuterium concentration in the gas mixture used to produce the flame is at least 10% by volume of the reducing gas present in the mixture. Preferably, substantially all of the reducing gas in the mixture is deuterium, with oxygen the oxidizing gas species.
