  • Optical transmission device based on direct-sequence-spread-spectrum time-division-multiple-access and method thereof
    Patent number: 12040887
    Abstract: The invention discloses an optical transmission device based on direct-sequence-spread-spectrum time-division-multiple-access, which includes a signal transmitting module and a signal receiving module. The transmitting module is connected with the receiving module by optical fibers. The transmitting module is used for receiving an external data sequence signal, encoding the external data sequence signal into a direct-sequence-spread-spectrum time-division-multiple-access electric signal and modulating the resulting electric signal into corresponding spread-spectrum optical signal for transmission by optical fibre. The receiving module is used for receiving the direct-sequence-spread-spectrum time-division-multiple-access optical signal, and sequentially performing photoelectric conversion, analog despreading, analog-digital conversion and clock recovery to obtain the external data sequence signal.
