Beschreibung
Zusammenfassung:	An apparatus and a method for producing a depressed-cladding core rod of an ultra-low water peak optical fiber, the apparatus including a core rod component, an inner cladding casing component, a high temperature heat source, chucks, a rotary joint, an external gas pipe, and a pressure controlling pipe. The core rod component is produced by fusing and splicing a core layer rod and a first hollow shaft together. The inner cladding casing covers the outside of the core layer rod. The inner cladding casing component is produced by fusing and splicing an inner cladding casing and a second hollow shaft together. These two hollow shafts are clamped in two chucks of a glass lathe. A high temperature heat source is arranged outside the inner cladding casing.
