Card-shaped optical data link device

A card-shaped optical data link device, comprising:

• an electric connector for receiving and transmitting an electric signal from and to an external environment;
• an electric signal processor electrically connected to said electric connector;
• an optical transmission module electrically connected to said electric signal processor, for converting the electric signal received from said electric signal processor into an optical signal;
• an optical reception module electrically connected to said electric signal processor, for converting an optical signal into an electric signal;
• an optical connector for supporting said optical transmission module and said optical reception module;
• a receiving portion formed in said optical connector for receiving an optical plug having a guide projection extending in a direction along which the optical plug is inserted into the receiving portion,
• said receiving portion having a cavity with an opening for receiving the optical plug, and said cavity being in communication with the outside of said receiving portion through a slot for receiving the guide projection, said slot having an opening on an edge of said opening of said cavity and extending in the insertion direction of said optical plug;
• a frame accommodating said electric connector and said electric signal processor, said optical transmission module and said optical reception module, said optical connector being incorporated into said frame and located at a position opposing said electric connector through said electric signal processor;
• and
• a pair of panels for sandwiching said frame and forming an envelope with said frame, said envelope housing said electric connector, said electric signal processor, said optical transmission module, said optical reception module and said optical connector;
• said guide projection of said optical plug being directly faced to at least one of said panels, when said optical plug is inserted into said receiving portion.
