An FSO transceiver (4) comprising a body (6), at least one lens (9) fixed to the body in a first position (C) and means for attaching a connector (11) for an optical fiber (3) at a second position (B) at a predefined distance (Zbc) to the lens, the lens being adapted to converge rays (8) of light sent to the FSO transceiver via free space into the optical fiber. The means for attaching the connector is a temperature compensation device (10) having an expansion coefficient being higher than an expansion coefficient of the body and that the temperature compensation device is fixed to the body in a third position (A) and has a free end which allows the temperature compensation device to expand or contract according to temperature changes, and that the second position is positioned between the third position and the first position.
An FSO transceiver comprising a body, at least one lens fixed to the body in a first position and a single-piece temperature compensation device for attaching a connector for an optical fiber at a second position at a predefined distance to the lens, the lens being adapted to converge rays of light sent to the FSO transceiver into the optical fiber, and wherein said temperature compensation device has an expansion coefficient that is higher than an expansion coefficient of the body and is fixed to the body in a third position, and further wherein said temperature compensation device has a free end that is not fixed to the body and allows the temperature compensation device to expand and contract according to temperature changes, to maintain the position of the optical fiber relative to the lens.
