Abstract
A fusion splicer for fusion-splicing a first group of optical fibers and a second group of optical fibers by arc discharge is disclosed. The fusion splicer includes first and second electrode rods, first and second fiber holding parts, and a first shield. The electrode rods generate the arc discharge therebetween. The first fiber holding part has a first plurality of V-grooves positioning the first group of optical fibers. The second fiber holding part has a second plurality of V-grooves positioning the second group of optical fibers. The first shield is located between the first and second plurality of V-grooves and the first electrode rod in a direction along a center line connecting a tip of the first electrode rod to a tip of the second electrode rod. The first shield is formed of an insulating material having heat resisting properties withstanding 1000 or more degrees Celsius.
