Abstract

A rare-earth doped optical fiber module including a resin reel having elasticity and a rare-earth doped optical fiber wound around the resin reel. The rare-earth doped optical fiber module further includes a single-mode optical fiber spliced to the rare-earth doped optical fiber and wound around the resin reel. The resin reel is formed of silicone rubber, fluororubber, or soft PVC.

1. 1. A manufacturing method for a rare-earth doped optical fiber module, comprising the steps of: setting a resin reel having elasticity on a metal reel whose diameter is changeable between a first diameter and a second diameter larger than said first diameter; increasing the diameter of said metal reel to said second diameter to thereby increase the diameter of said resin reel; winding a rare-earth doped optical fiber around said resin reel; decreasing the diameter of said metal reel to said first diameter; and removing said resin reel having said rare-earth doped optical fiber from said metal reel.
