On the other hand, the third opto-converter 191E of the one-to-many conversion device 190E performs opto-conversion on one of the plurality of first sub-opto-converted signals and one of the plurality of second sub-opto-converted signals, wherein the plurality of second sub-opto-converted signals are optical signals.

The front-end processor 163E is used to perform signal processing on one of a plurality of third photoelectric conversion signals and radio frequency signals.

[0078] Since the wireless radio frequency conversion system 100E in Figure 8 uses multiple photoelectric converters and fiber optic networks to connect the components, the components of the wireless radio frequency conversion system 100E can be respectively arranged on different sides of the wireless radio frequency conversion system 100E. This makes the circuit design of the wireless radio frequency conversion system 100E more flexible and simpler. It should be noted that in the embodiment of Figure 8, the component labels are similar to those in Figures 5 and 6, possessing similar structural and electrical operating characteristics. For the sake of brevity, they will not be described in detail here. Furthermore, this invention is not limited to the architecture shown in Figure 8; it is merely used to illustrate one implementation method of this invention to facilitate understanding of the technology. The patent scope of this invention should be determined by the scope of the invention application.

[0079] Figure 9 is a detailed circuit block diagram illustrating a wireless radio frequency conversion system 100C as shown in Figure 5, according to an embodiment of this disclosure. It should be noted that, compared to the wireless radio frequency conversion system 100E shown in Figure 8, the main distribution device 140F of the wireless radio frequency conversion system 100F in Figure 9... The fiber optic network 150F and the multiple remote antenna devices 160F differ as follows.

[0080] As shown in the figure, the wireless radio frequency conversion system 100F has a plurality of main distribution device-side photoelectric converters 145F, which are used to perform photoelectric conversion on a plurality of first sub-photoelectric conversion signals to generate a plurality of optical signals, which are then transmitted through a plurality of optical fiber networks 150F. For example, the four main distribution device-side photoelectric converters 145F of the wireless radio frequency conversion system 100F transmit individual signals to the antenna-side photoelectric converters 161F of four remote antenna devices 160F located on the top floor 910F of the building 900F via four optical fiber networks 150F. In this way, since the wireless radio frequency conversion system 100F in Figure 9 transmits individual signals to the top floor 910F of the building 900F through independent main distribution device-side photoelectric converters 145F, optical fiber networks 150F, and remote antenna devices 160F, users on the top floor 910F of the building 900F can receive signals of better quality.

[0081] Furthermore, the one-to-many conversion device 190F of the wireless radio frequency conversion system 100F includes a third opto-converter 191F, an optical fiber network 193F, and a one-to-many distribution device 195F. The optical fiber network 193F connects the third opto-converter 191F and the one-to-many distribution device 195F. The third opto-converter 191F receives signals from the radio frequency processor 143F and performs opto-conversion on one of a plurality of first sub-opto-electric conversion signals to generate one of a plurality of second sub-opto-electric conversion signals, which may be optical signals. The one-to-many distribution device 195F receives signals from the optical fiber network 193F and distributes one of the plurality of second sub-opto-electric conversion signals into a plurality of second opto-electric conversion signals. For example, a single signal transmitted from a single fiber optic network 193F can be received on the 900th floor of a building. The single signal is then distributed into multiple signals through a one-to-many distribution device 195F. Therefore, users on the 900th floor of a building can transmit signals through a single fiber optic network 193F without the need for multiple fiber optic networks, thereby saving the construction cost of the wireless radio frequency conversion system 100F.

[0082] Since the wireless RF conversion system 100F in Figure 9 uses multiple photoelectric converters and fiber optic networks to connect the components, the components of the wireless RF conversion system 100F can be respectively arranged on different sides of the wireless RF conversion system 100F. This makes the circuit design of the wireless RF conversion system 100F more flexible and simpler. It should be noted that in the embodiment of Figure 9, the component labels are similar to those in Figures 5 and 6, possessing similar structural and electrical operating characteristics. For the sake of brevity, these will not be elaborated upon here. Furthermore, this invention is not limited to the architecture shown in Figure 9; it is merely used to illustrate one implementation method of this invention to facilitate understanding of the technology. The patent scope of this invention should be determined by the scope of the invention application. Modifications and refinements made by those skilled in the art to the embodiments of this invention without departing from the spirit of this invention still fall within the scope of the invention application.

The first connector 1300 outputs the first reflected signal through the optical fiber network 1950. The second beam splitter 1400 partially reflects the first transmitted signal to generate a second reflected signal and partially transmits the first transmitted signal to generate a second transmitted signal. The second connector 1500 outputs the second reflected signal through the optical fiber network 1950.

[0100] As shown in Figures 14 to 17, these transmission spectra can be applied to filters 1130B and 1130C, first beam splitters 1200B and 1200C, second beam splitters 1400B and 1400C, and third beam splitters 1600B and 1600C of one of the multi-distribution devices 1000B and 1000C shown in Figures 12 and 13, to achieve bidirectional transmission of the photoelectric converter in the room.

Therefore, the optical signal can pass through the filters 1130B and 1130C. Subsequently, the optical signal is transmitted to the first beam splitter 1200B and 1200C, the second beam splitter 1400B and 1400C, and the third beam splitter 1600B and 1600C.

Assuming that the energy level of the optical signal of each connector is equal, the transmission efficiencies of the first beam splitter 1200B and 1200C, the second beam splitter 1400B and 1400C, and the third beam splitter 1600B and 1600C are 75% as shown in Figure 15, 67% as shown in Figure 16, and 50% as shown in Figure 17, respectively.

The optical signals from the second connectors 1500B and 1500C are reflected by the second beam splitters 1400B and 1400C and transmitted through the first beam splitters 1200B and 1200C. The optical signals from the third connectors 1700B and 1700C are reflected by the third beam splitters 1600B and 1600C and transmitted through the first beam splitters 1200B and 1200C and the second beam splitters 1400B and 1400C. The optical signals of the fourth connectors 1800B and 1800C are transmitted through the first beam splitter 1200B and 1200C, the second beam splitter 1400B and 1400C, and the third beam splitter 1600B and 1600C.

[0106] The optical signals from the first connectors 1300B and 1300C, the second connectors 1500B and 1500C, the third connectors 1700B and 1700C, and the fourth connectors 1800B and 1800C are all transmitted to the bidirectional optical transmitter and receiver 1100B and 1100C, and then reflected by the filters 1130B and 1130C to the photodiode package structure (RX TO-can) 1120B and 1120C.
