Patent ID: 7539367

Claim:
An optical communication module, comprising: a transmitting optical element array which transmits a plurality of optical signals; a receiving optical element array which receives a plurality of optical signals; an optical component which converts light paths of a transmitting light outputted from said transmitting optical element and a receiving light received by said receiving optical element array; an optical element assembly in which said transmitting optical element array and said receiving optical element array are assembled in a package; a circuit substrate which is connected to said optical element assembly; an optical fiber, the optical signals being inputted to said optical fiber and being outputted from said optical fiber; at least two inclined surfaces inclining with regard to a light axis of said optical fiber; an optical functional component which transmits or reflects the optical signals depending on a wavelength, said optical functional component being formed in one of said inclined surfaces; a reflection surface which reflects the optical signs, said reflection surface being formed in one of said inclined surfaces; and a lens which is formed in a fiber side end face of said optical component, wherein wherein said optical fiber is inserted in a ferrule, said optical component and the ferrule are optically coupled by butt-connecting and integrally fixed by placing a mechanically transferable (MT) clip from above; and the MT clip comprises means for preventing a reflection light of the optical signals transmitting from said optical functional component from inputting into said transmitting optical element array or said receiving optical element array.
