Abstract
An optical transmission line with reduced splice loss, and methods for fabricating an optical transmission line with reduced splice loss, are described. In one described method, a length of dispersion-compensating fiber, or other suitable first transmission fiber, is spliced to a first end of a length of a bridge fiber. The splice is heated to a maximum temperature to cause a measurable reduction in splice loss. The temperature of the splice is then ramped down to room temperature, such that the reduction in splice loss is maintained. A second end of the bridge fiber is then spliced to a length of a second transmission fiber. Further described is a technique for determining the maximum temperature for heating the splice between the first transmission fiber and the bridge fiber.
