Abstract

A method for manufacturing a trench-type optical fiber with excellent bending loss characteristics includes: (a) forming a core and a first clad layer by means of deposition; (b) preparing a tube containing hydroxyl (OH ) impurities not exceeding a predetermined level, and joining the tube around the first clad layer by means of over-cladding to form a second clad layer; and (c) forming a third clad layer around the second clad layer.
