Abstract
An optical part module has an optical amplification fiber in a small space without damage or losing its optical characteristics. An optical amplification fiber connects optical parts in the case. The optical amplification fiber has a predetermined length which creates a large play in length. A part of the optical amplification fiber creating the play in length is wound on the bobbin. The winding operation is performed while turning the bobbin upside down for each single turn of the winding so that twist generated in the optical fiber due to winding is canceled.
