Optical module and optical communication system

An optical communication system comprising:

• a data source and an optical channel,
• wherein the system further comprises an optical module, and the optical module comprises an upper housing, a printed circuit board, a lower housing, and an integrated chip and an optical transceiver module arranged on the printed circuit board, the upper housing and the lower housing together forming a space accommodating the printed circuit board, the integrated chip, and the optical transceiver module,
• wherein the optical module further comprises:
• a first flexible thermally conductive component, arranged between the printed circuit board and the lower housing;
• one surface of the first flexible thermally conductive component is contacted with the integrated chip, and another surface of the first flexible thermally conductive component is contacted with the lower housing, and the two surfaces are opposite to each other, wherein a first surface of the upper housing comprises at least one protrusion which exerts pressure against the printed circuit board to facilitate thermal contact of the integrated chip to the one surface of the first flexible thermally conductive component, and
• wherein the data source is configured to transmit data signals to the optical module, and the optical transceiver module of the optical module is configured to convert the data signals into optical signals, and transmit the optical signals via the optical channel.
