PROBLEM TO BE SOLVED: To provide an optical amplifier module, upsizing of which can be suppressed while avoiding interference of an optical amplifier unit and other electronic components.SOLUTION: An optical amplifier module 3 having a booster amplifier unit 15 and a preamplifier unit 16 housed removably in a housing space 20 formed in a chassis 2, and outputting an inputted optical signal while amplifying, includes a main substrate 31 provided with a module side connector 18 for connection with a chassis side connector 6 arranged in the back side of the housing space 20, and a sub-substrate 32 arranged to be perpendicular to the main substrate 31. The booster amplifier unit 15 and preamplifier unit 16 are connected with connectors 141, 142 for connection with the amplifier unit provided on the sub-substrate 32. |
