Abstract: A passive optical network device comprising a casing, printed circuit board, and fiber optic transceiver system is provided. The fiber optic transceiver system comprises a fiber optic components device, fiber optic transceiver, and RF connector. During operation, the fiber optic components device converts optical signals from the fiber optic transceiver to digital signals, and then transmits the converted digital signals to external electronic systems via the hot-pluggable transceiver connection interface. The fiber optic components device converts digital signals from the external electronic systems to optical signals, and then transmits the optical signals to other external electronic systems via the fiber optic transceiver. The RF connector transmits RF signals from additional external electronic systems to the external electronic systems via the hot-pluggable transceiver connection interface.

Abstract: A device and method of optical fiber condition monitoring in optical networks is described. The front end of each branch of the optical network is installed with an optical filter that can filter an optical signal with a different wavelength. Optical signals of different wavelengths enter each of the branches in sequence for analysis, so that the condition of each branch on the optical network can be determined. This solves the problem of interference among the branches when monitoring the optical fiber condition on an optical network.
