Abstract
A module structure that makes it easy to mount pigtail optical fibers by mounting a wavelength conversion apparatus, to enable adjustment of the path distance of optical signals, or to control the path distance of each individual polarization for polarization diversity control with high precision. The wavelength conversion apparatus is characterized in that when mounting a module having two or more input and output ports of a wavelength conversion apparatus, the module is configured to take out the input and output ports from two corresponding walls of the mounting housing, and also has a mechanism to control the path distance of at least one of the signal light and the excitation light input from each input and output port, and has a mechanism to separate the polarization of at least one of the signal light and the excitation light input from the ports and to control the path distance.
