Patent ID: 8721194

Claim:
An optical transceiver module, comprising: a circuit substrate carrying thereon an optical transceiver sub-module for converting electrical signals to and from optical signals; a z-axis positioning base connected to a surface of the circuit substrate that carries the optical transceiver sub-module, wherein the z-axis positioning base comprises two first sides respectively provided on two lateral sides of the optical transceiver sub-module, a second side provided between and connecting the two first sides, an opening corresponding in position to a side of the optical transceiver sub-module that faces away from the second side, and a step difference provided on each of the two first sides and the second side; and a fiber-optic lens element provided on the z-axis positioning base, the fiber-optic lens element comprising a cover and a fiber-optic lens sub-module, wherein the fiber-optic lens sub-module is embedded in a lower surface of the cover; wherein the fiber-optic lens sub-module has a lower surface provided with a plurality of condensing lenses corresponding in position to the optical transceiver sub-module and has a surface which is perpendicular to the lower surface provided with the condensing lenses and which has an optical fiber connection port provided with a plurality of condensing lenses, and the fiber-optic lens sub-module is provided therein with a reflective element for, within the fiber-optic lens sub-module, reflecting light-wave signals of the optical fiber connection port into the optical transceiver sub-module or reflecting light-wave signals of the optical transceiver sub-module into the optical fiber connection port, the optical fiber connection port being exposed through the opening of the z-axis positioning base; and wherein the cover comprises a recess in which the fiber-optic lens sub-module is embedded and step differences surrounding the recess and respectively corresponding in position to the step differences provided on the two first sides and the second side of the z-axis positioning base, so as for the cover to be fitted on the z-axis positioning base.
