Abstract
In an optical module, a package includes an array of first optical elements and at least one first positioning member. A microlens array plate including microlenses is fixed to the package, so that each of the microlenses corresponds to one of the first optical elements. An optical array connector mounts second optical elements thereon. The optical array connector has a light path bending portion for bending light paths of the second optical elements and at least one second positioning member. The optical array connector abuts against the package by aligning the second positioning member to the first positioning member so that each of the first optical elements corresponds to one of the second optical elements, A clamping member clamps the optical, array connector to the package.
