<title>Improving the transmittance of compound glass optical fibers</title>

This paper analyzes all factors affecting the transmittance of compound glass optical fibers. By studying pre-treatment of raw materials, optical structure design of compound glass fibers, glass level control and temperature field control of the double crucible, a proper production process and all parameters to be controlled for making compound glass optical fibers have been established. Finally, the optical transmittance of optical fibers made...
