The optical connector includes an optical boundary surface on which light emitted from an optical fiber is incident; a reflector changing the direction of traveling of light incident through the optical boundary surface; and a lens emitting light reflected through the reflector outside. The reflector has a cylindrical shape and converts light incident on the reflector into light traveling parallel to a first direction, and the lens has a cylindrical shape and converts light incident on the lens into light traveling parallel to a second direction which is perpendicular to the first direction. ## Claims ### Claim 1 An optical connector, comprising: an optical boundary surface on which light emitted from an optical fiber is incident; a reflector changing a direction of traveling of light incident through the optical boundary surface; and a lens emitting light reflected through the reflector outside, wherein the reflector has a cylindrical shape and converts light incident on the reflector into light traveling parallel to a first direction, and the lens has a cylindrical shape and converts light incident on the lens into light traveling parallel to a second direction which is perpendicular to the first direction. ### Claim 2 (depends on 1) The optical connector of claim 1, wherein the first direction is perpendicular to both the direction of light incident on the reflector and the direction of reflection. ### Claim 3 (depends on 1) The optical connector of claim 1, wherein the second direction is perpendicular to both the direction of light incident on the lens and the first direction. ### Claim 4 (depends on 1) The optical connector of claim 1, wherein the light emitted through the lens has a wider width in the second direction than in the first direction and travels in parallel. ### Claim 5 (depends on 1) The optical connector of claim 1, wherein the reflector is a prism in a form of a cylindrical lens. ### Claim 6 (depends on 1) The optical connector of claim 1, wherein the lens is a cylindrical lens. ### Claim 7 (depends on 1) The optical connector of claim 1, wherein the direction of light incident on the lens is changed by the reflector to be incident on the optical fiber. ### Claim 8 (depends on 1) The optical connector of claim 1, wherein the optical connector is bottom-to-bottom coupled to another optical connector. ### Claim 9 (depends on 8) The optical connector of claim 8, wherein the optical connector, when coupled to another optical connector, has a lens of the optical connector facing a lens of the another optical connector. ### Claim 10 (depends on 8) The optical connector of claim 8, comprising: parts coupled in a gradient structure in opposite directions to each other when coupled with another optical connector. ### Claim 11 (depends on 10) The optical connector of claim 10, wherein the parts coupled in a gradient structure in opposite directions to each other are a coupling protrusion and a front side part. ### Claim 12 (depends on 8) The optical connector of claim 8, comprising guide parts formed at opposite inclinations to each other to guide smooth coupling when coupled with another optical connector. ### Claim 13 (depends on 1) The optical connector of claim 1, wherein the optical connector is coupled with a plurality of optical fibers, comprises reflectors in equal numbers as the optical fibers, and comprises the one lens. ### Claim 14 (depends on 1) The optical connector of claim 1, comprising a body part and a cover part. ### Claim 15 (depends on 14) The optical connector of claim 14, wherein the cover part and the body part have protrusions and grooves fittedly coupled to each other. ### Claim 16 (depends on 14) The optical connector of claim 14, wherein the body part comprises an optical fiber guide capable of seating at least one optical fiber. ### Claim 17 (depends on 1) An optical cable module comprising the optical connector of claim 1. ### Claim 18 (depends on 1) An optical transceiver module comprising the optical connector of claim 1. ### Claim 19 (depends on 1) An active optical cable, comprising: an optical cable module comprising the optical connector of claim 1; and an optical transceiver module comprising the optical connector of claim 1. ### Claim 20 (depends on 1) An active optical cable, comprising: two optical cable modules; and an optical transceiver module comprising two insertion holes, wherein the optical cable module comprises the optical connector of claim 1, the insertion hole allows the optical cable modules to be coupled one by one, and the insertion hole comprises the optical connector of claim 1.
