The invention relates to a method for preparing a mutant organic polymer optical fiber by one step through continuous multiplayer co-extrusion and a device applicable to the method. The method comprises the following steps of: placing a core layer polymer material, a light reflecting layer polymer material, a flexible layer polymer material and a cladding layer polymer material which have different physical properties in respective screw extruders, heating and melting, then allowing the melted materials to pass through the respective screw extruders and organic polymer melt gear pumps arranged at the outlets of the screw extruders, enter the inlets of co-extrusion die heads with n layers of concentric rings in each layer respectively through the outlets of respective organic polymer melt gear pumps, then extruding synchronously through the respective outlets of the co-extrusion die heads with n layers of concentric rings, forming a plurality layers of concentric round bars through the machine head outlets of
