Optical communication device, optical transceiver using the same and manufacturing method of optical communication device

An optical communication device, comprising:

• a first means for including at least the optical module which inputs or outputs an optical signal, and the peripheral circuit connecting electrically with the optical module:
• a second means for including an electric connector which inputs and/or outputs an electric signal;
• and
• a third means for adjusting a relative position of the module board and the connector board, and transmitting the electric signal among these boards.

An optical transceiver, comprising:

• the optical communication device, further comprising:
• a module board which includes at least the optical module for inputting and/or outputting an optical signal, and the peripheral circuit connecting electrically with the optical module;
• a connector board which includes an electric connector inputting and/or outputting an electric signal;
• and
• a flexible board which adjusts a relative position of the module board and the connector board, and transmits the electric signal among these boards;
• and
• a case, further comprising:
• a mount part which receives the optical communication device;
• a cable connecting part that optically connects a communication cable with the optical module;
• and
• a main body connecting part that electrically connects an electrical connector with a main communication device:
• wherein:
• the optical module transforms the optical signal received via the communication cable into electric signal, and outputs to the main communication device via the electric connector;
• and
• the optical module transforms the electric signal received from the main communication device via the electric connector into the optical signal, and outputs to the communication cable.
