摘要： PROBLEM TO BE SOLVED: To provide an optical fiber module suitably used in a lumped constant type Raman amplifier. SOLUTION: In the optical fiber module 100, a minimum bending diameter D 1 of an optical fiber 110 for Raman amplification is set to be ϕ140 mm or smaller and more suitably ϕ60 mm or smaller. Because the minimum bending diameter D 1 is made small in a starting portion of winding of the optical fiber 110 for Raman amplification, an effective cutoff wavelength is shortened. Out of pumped light reaching the starting portion of winding of the optical fiber 110 for Raman amplification from a pigtail optical fiber 120, higher order mode propagation light is cut off at the starting portion of winding and only ground mode light passes through the starting portion of winding and is made incident on the optical fiber 110 for Raman amplification.
