受けることになり好甘しくない。As shown in the figure, the LD or APD 4 mounted on the unit 3 housed in the rack IK is conventionally placed at the bottom of the unit 3 because it has a characteristic of being sensitive to heat. Optical fiber cords 6 and 7 drawn out from the LD and APD 4 to the overhead terminal section 9 are connected to the connector at the upper part of the unit 3. In this case, if the LD or APD 4 is placed on the upper part of the unit 3 and its connector part is exposed to the extra length storage chamber 8, the optical connector 5 and the optical fiber cord 6 are unnecessary and the cost can be reduced. It becomes possible. However, arranging the LD, A, and PD 4 at the top of the unit and the unit 3 is not preferable because they will be affected by the high temperature atmosphere that is trapped at the top of the unit.
