Abstract
An optical fiber end face processing method, an optical fiber end face formed using the processing method and a processing apparatus used in the optical fiber end face processing method. The processing method comprises: chamfering and fusion splicing: providing a heat source to an optical fiber end face (3) formed in cutting of an optical fiber to perform chamfering and fusion splicing on an outer edge (33) of the optical fiber end face (3); end face forming: enabling the outer edge (33) of the optical fiber end face (3) to form a cambered surface or a chamfering inclined surface through a surface tension effect of a liquid-state part of the optical fiber at an end of the optical fiber. A processing part of the optical fiber end face processing method has a small area. The processed optical fiber end face is smooth and flat, facilitates butting, and prevents a fiber core and a near end face thereof from being hot melted and bonded, thus keeping a cross-sectional shape of the processing part and improving an optical fiber butting transmission indicator.
