Patent ID: 8204351

Claim:
An optical module, comprising: an optical assembly incorporating a light emitting device or a light receiving device for converting one of an electrical signal and an optical signal into another of the electrical signal and the optical signal; a circuit board electrically connected to the optical assembly; an optical fiber optically connected to the optical assembly; a tray for winding the optical fiber therein and pulling out the optical fiber therefrom; and a case receiving the optical assembly, the circuit board, the optical fiber, and the tray, wherein: the tray is fixed with respect to the case so as to be reciprocatingly movable within a restricted range, the tray is fixed to the case so as to be rotatable, the tray is moved from a position to another position within the restricted range so as to be moved away from an electrical connection section between the optical assembly and the circuit board, and the optical fiber is pulled out from a center axis of rotation of the tray.
