OPTICAL TRANSCEIVING MODULE, PASSIVE OPTICAL NETWORK SYSTEM, OPTICAL FIBRE DETECTION METHOD AND SYSTEM

摘要

This application provides an optical transceiver module, including an optical component and a drive component connected to the optical component, where the optical component includes: a data signal transmitter, configured to transmit a first data signal that is carried by a first wavelength, and transmit a first test signal that has the first wavelength to an optical network under control of the drive component; a test signal receiver, configured to receive a reflection signal of the first test signal; a test signal transmitter, configured to transmit a second test signal that is carried by a second wavelength to the optical network under control of the drive component; and a data signal receiver, configured to receive a second data signal that has the second wavelength and receive a reflection signal of the second test signal. This application further provides a passive optical network system and device, and a fiber detection method and system.
