https://www.meisuoptics.com/products/2d-collimator-array/ Traditional optical fiber collimator is the basic component of optical fiber communication device. However, with the development trend of integration and miniaturization, fiber optical switch, optical cross connection such as N * M equipment, and wavelength selection switch are now all needed to start using densely arranged collimator arrays; whereas, the existing single fiber collimator is too big to be applied. Therefore, 2D optical fiber collimator array with precise pitch have now gradually become the necessary choices for numerous optical integrated devices.
