GPON terminal transmitting-receiving-integrated optical assembly with RSSI function

The invention discloses a GPON terminal transmitting-receiving-integrated optical assembly with an RSSI function. The GPON terminal transmitting-receiving-integrated optical assembly comprises a receiving module, a wavelength division multiplexing module and a transmitting module which are connected with one another sequentially; the receiving module converts optical signals transmitted by an optical fiber into electrical signals; the transmitting module converts the electrical signals into optical signals and transmits the optical signals out; the wavelength division multiplexing module can realize single fiber bidirectional transmission through wavelength division multiplexing technology; and a mirror current source used for detecting signal strength is integrated inside the receiving module. According to the GPON terminal transmitting-receiving-integrated optical assembly with the RSSI function, the mirror current source is integrated inside the transmitting-receiving-integrated optical assembly, and there
