摘要： A filter module includes a first optical fiber collimator, a second optical fiber collimator, and a filter located between the first and second optical fiber collimators. The first optical fiber collimator includes a first optical fiber, a first optical fiber chip for holding the first optical fiber, and a first lens. The second optical fiber collimator includes second optical fibers, a second optical fiber chip for holding the second optical fiber, and a second lens. The filter is located between and coaxial with the first and second lenses. The filter, the first lens, and the second lens form a center piece of the filter module.

摘要： A method of aligning a fiber collimator in a short time. Light emitted from a collimator is reflected by a mirror. Reflected light passes through the collimator, and is measured by a light intensity measuring device. Rotating bodies rotatably support the mirror about an X-axis and a Y-axis orthogonal to the optical axis. An aligner simultaneously drives the rotating bodies to scan an optimal angle for the mirror. With the mirror fixed at the optimal angle, the distance between a collimation lens of the collimator and the optical fiber is changed. Subsequently, the optimal angle of the mirror is again scanned.

摘要： In an optical tap module, a first lens, a focusing lens, and a photodiode are arranged such that a center axis of a cylindrical case housing the first lens, the focusing lens, and the photodiode is substantially located on the same line. When light propagates through a second optical fiber and is emitted from an end surface facing the first lens so as to be incident on an optical filter, and light transmitted the optical filter is converged by the focusing lens, the photodiode and a chip mounting support are arranged such that a focal point of light is located spatially distant from the surfaces of the photodiode and the chip mounting support.
