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

摘要

Provided is an optical transceiving module, including an optical assembly and a drive assembly connected thereto, wherein the optical assembly includes a data signal transmitter for transmitting a first data signal with a first wavelength and transmitting a first test signal with the first wavelength to an optical fibre network under the control of the drive assembly, a test signal receiver for receiving a reflection signal of the first test signal, a test signal transmitter for transmitting a second test signal with a second wavelength to the optical fibre network under the control of the drive assembly, a data signal receiver for receiving a second data signal with the second wavelength and receiving a reflection signal of the second test signal. Also provided are a passive optical network system and device and a method and system for optical fibre detection.
