Abstract:
1. An optical communication module comprising: an optical fiber cable; a first optical element disposed so that an optical axis thereof is substantially parallel to an optical axis of the optical fiber cable, and configured to transmit or receive a first optical signal; a second optical element disposed so that an optical axis thereof is substantially parallel to the optical axis of the optical fiber cable, and configured to transmit or receive a second optical signal; an optical path changing component disposed between the optical fiber cable and the second optical element; and an optical filter disposed between the optical fiber cable and the first optical element, and configured to transmit the first optical signal and to reflect the second optical signal; an optical filter mounting portion formed by cutting out a side portion of the optical path changing component; and an optical filter fixing component fixing a position of the optical filter by interposing the optical filter between the optical filter mounting portion and the optical filter fixing component, wherein the optical path changing component and the optical filter twice bend an optical path of the second optical signal by 90° every time wherein the optical filter is neither bonded nor welded to the optical path changing component at least at an optical path of the optical path changing component.
