Optical transceiver with optical sub-module thermally couples with optical transceiver without mechanical stress

An optical transceiver, comprising:

• an optical transmitting module including a sleeve portion and a box portion, the sleeve portion being optically coupled with an optical fiber and the box portion housing a light emitting device therein;
• a support member for supporting the optical transmitting module, the support member having top, bottom and side portions, the side portion connecting the top and bottom portions, the top and bottom portions sandwiching the box portion of the optical transmitting module therebetween,
• an elastic member put between one of top and bottom portions of the supporting member and the optical transmitting module, the elastic member pushing the optical transmitting module against the other of the top and bottom portions of the support member;
• and
• a housing for enclosing the optical transmitting module and the support member therein, the housing having a primary surface for installing the optical transmitting module thereon through the support member, the top and bottom portions of the support member extending substantially in parallel to the primary surface of the housing,
• wherein the sleeve portion of the optical transmitting module is rigidly fixed to the housing and the box portion is flexibly fixed to the housing through the support member.
