Embodiment Construction

[0058] Features of the present invention are described below. The material used in the optical waveguide path is not particularly limited. Materials such as plastic fibers and glass fibers are commonly used. Due to the short propagation distance of the optical signal, it is ideal to use plastic fibers which are easy to handle. The type of optical signal is not particularly limited. Optical signals having a single wavelength or multiple wavelengths can be used. In the case of using multi-wavelength optical signals, in order to distinguish between multiple wavelengths, it is desirable to use a multilayer dielectric film or a diffraction grating type mixer / separator, etc. as the first reflection means and / or the second reflection means device.

[0059] figure 1 A simplified diagram of the structure of the module 100 is shown. The module 100 has a plurality of substantially square circuit boards 20 , a fixing member 10 that fixes the plurality of circuit boards 20 and provid...

Abstract

An optical connector has a body, a mirror provided within the body, an optical waveguide path, and a linking section. The optical waveguide path extends from a first end face exposed on a part of the surface of the body, bending via the mirror up to a second end face exposed on a part of the surface of the body not parallel to the first end face. The linking section is farmed so as to includes the first end face and has a mechanism linking the fixing member first end face to the second end face of the optical waveguide path of the fixing member.

Description

technical field [0001] The invention relates to a module having a plurality of circuit boards stacked at a prescribed distance from each other, wherein optical communication paths are provided between the circuit boards. The present invention also relates to an optical connector providing an optical communication path extending in a direction different from the axial direction of the optical communication path provided between circuit boards. Background technique [0002] The development trend of the module is to stack a plurality of circuit boards at a defined distance from each other, said circuit boards are equipped with circuits composed of electronic and electrical components. In this type of module, one circuit board and another circuit are fixed parallel to each other by fixing members. By stacking a plurality of circuit boards in such a way as to intervene the fixing member, it is possible to save space within the module compared to a case where a plurality of circu...
