Abstract
In a process of splicing optical fibers, a temperature distribution during the splicing of the waveguides at a constant discharge current will depend on ambient parameters, which include temperature, air pressure and air humidity, and these parameters also influence the quality of the splice being produced. The discharge current is regulated by measuring the actual intensity distribution of the thermionic emissions of the waveguide during the splicing operation and by comparing this intensity distribution with a stored reference intensity distribution. The device includes a sensor which is used for measuring the intensity distribution and for adjusting the ends of the waveguides relative to each other.
