Abstract:
A method for loading a transmission or receiving module for an optical link to be connected to optical fibers, comprising the steps of:installing at least a pair of optical fibers at a fiber installing part; arranging a light emitting element and a light receiving element in a direction of an optical axis of said pair of optical fibers installed at the fiber installing part; integrally forming a rigid central circuit board electrically connected to root portions of lead terminals of the light emitting element and the light receiving element and being mechanically and electrically connected at one side edge thereof to a side edge of a first rigid side circuit board by a flexible circuit board and being mechanically and electrically connected at an other side edge opposite the first side edge to a side edge of a second rigid side circuit board by the flexible circuit board; and folding the first rigid side circuit board and the second rigid side circuit board at substantial right angles, respectively, to the rigid central circuit board in such a way that the first rigid side circuit board and the second rigid side circuit board are facing away from each other.
