PURPOSE:To materialize the miniaturization accompanied with the reduction of development cost and development period of a transmission-reception integrated optical transmission module and improve the yield rate by the independent adjustment and evaluation of each transceiver. CONSTITUTION:By putting the inner structure of a transmission-reception integrated optical transmission module in two-storied structure of a board 1 for transmitter and a board 8 for receiver as shown in the figure, the effective mounting face is made four sides, and further by fixing element modules 2 and 9 to outside covers 6 and 17, the effective area of the board is enlarged, whereby the above purpose can be accomplished. It has enabled the miniaturization accompanied with the development cost reduction and the development period reduction of a transmission medium and enabled the enlargement of the effective area inside the board and the improvement of yield rate. |
