Abstract

The invention relates to a time-division multiplexing (TDM) optical fiber network system and a method thereof. The TDM optical fiber network system comprises a plurality of cable data machines, a plurality of TDM optical transceivers, an optical splitter and an optical terminating machine, wherein during uploading, the TDM optical transceivers convert upload electric signals into parallel upload optical signals respectively and transmit the parallel upload optical signals in different time slots in a TDM manner, and the optical splitter is connected in series with the parallel upload optical signals to form a serial upload optical signal and transmits the serial upload optical signal to the optical terminating machine; and during downloading, the optical splitter decomposes a serial download optical signal into a plurality of parallel download optical signals in the TDM manner and transmits the parallel download optical signals in different time slots, and the TDM optical transceivers convert each parallel download optical signal into a download electric signal and transmit the download electric signals to the cable data machines.

Description

technical field [0001] The invention relates to a multiplexing system of an optical fiber network, in particular to a time-division multiplexing optical fiber network system and a method thereof. Background technique [0002] The bandwidth of the existing optical fiber communication is larger than that of other communication technologies, so it can transmit a larger amount of data and provide users with better network services. [0003] like Figure 4 As shown, the existing optical fiber network mostly adopts the hybrid fiber-coaxial (HFC) architecture, which means that the main line part from the optical terminal 90 in the computer room to an optical transceiver 91 adopts optical fiber transmission, and then at the end part, through the main line The splitter 92 divides the signal into multiple coaxial cables and transmits them to the cable modem 93 or TV 94 of the client in a dendritic structure. However, the electronic products (such as TV, modem, etc.) The generated noi...
