The front end of the printed plate is connected with the optical module, and the rear end of the printed plate is provided with a leading leg. The utility model is characterized in that the printed plate is integrated with a boosted circuit. The optical module is composed of a wave separator, an avalanche photodiode and a laser. The bias voltage output of the boosted circuit is connected with the input of the avalanche photodiode. The module can provide relatively large extending space. When the optical transmitting/receiving module is used with high density, the product design is simplified, the production and maintenance costs are reduced, and the optical reception sensibility is highly increased. The utility model is chiefly used for the single fiber bi-directional communication whose communication rate is more than billion bit per second.
