PROBLEM TO BE SOLVED: To achieve size reduction of an optical amplifier module while preventing an optical fiber from being bent at a small curvature radius.SOLUTION: An optical amplifier module includes: a housing including a front panel 110 on which an optical connector is provided; a circuit board 14 partitioning an interior of the housing into a first storage space 11a and a second storage space 11b; a preamplifier unit 15 stored in the first storage space 11a; and a booster amplifier unit 16 stored in the second storage space 11b. A first extra length storage unit 11c is formed between a back surface plate 115 of the first storage space 11a and the preamplifier unit 15 for storing an extra length part of an optical fiber, and a second extra length storage unit 11d is formed between the front panel 110 and the booster amplifier unit 16, the second extra length storage unit 11d being present offset to the front panel 110 with respect to the first extra length storage unit 11c. |
