Self-adaptive rate photoelectricity conversion device

The utility model discloses a self-adaptive rate photoelectricity conversion device which is formed by an optical signal receiving device, a data recovery and switching switch, an optical signal transmitting device, and a controller which are connected sequentially. The controller, through an I2C bus, is respectively connected to the optical signal receiving device, the data recovery and switching switch, and the optical signal transmitting device; the self-adaptive rate photoelectricity conversion device also includes a power supply which is respectively connected with the controller, the optical signal receiving device, the data recovery and switching switch, and the optical signal transmitting device. In the utility model, one single device can easily meet the transmission requirement of the over-100G capacity; each service export can transmit in the self- adaptive rate; the service signal can be switched arbitrarily; the service signal N + 1 protection and the broadcast function can be realized; and the s
