As shown, the wireless radio frequency transceiver 110D includes at least one first antenna 111D and a first remote wireless device 113D. Furthermore, the wireless radio frequency transmission device 150D includes a second remote wireless device 151D and at least one second antenna 153D.

[0070] In operation, at least one first antenna 111D is used to transmit and receive radio frequency (RF) signals. Subsequently, a first remote wireless device 113D receives the RF signal and generates a data signal. Next, the data signal is transmitted to a second remote wireless device 151D via a first conversion device 120D, an optical fiber 130D, and a second conversion device 140D. Finally, the second remote wireless device 151D receives the data signal and generates a terminal signal. At least one second antenna 153D receives and transmits the terminal signal. For example, the first remote wireless device 113D can be a Remote Radio Unit (RRU), which receives the radio frequency millimeter wave signal from the first antenna 111D, and then amplifies, filters, switches, etc., the radio frequency millimeter wave signal to generate a data signal. The data signal can be an electrical signal such as a communication signal 191, a control signal 192, or a resonant signal 193, etc. The aforementioned communication signal 191 can be a millimeter wave high frequency signal, an intermediate frequency signal, a backhaul signal, or an IQ frequency modulation signal.

[0071] Next, the first remote radio unit 113D transmits the aforementioned communication signal 191, control signal 192, or resonant signal 193, etc., electrical signals to the first conversion device 120D. The first conversion device 120D converts the electrical signals into optical signals and transmits them to the second conversion device 140D via optical fiber 130D. The optical fiber 130D may contain one or more optical fibers to facilitate the transmission of the optical signals between the first conversion device 120D and the second conversion device 140D. Subsequently, the second conversion device 140D converts the optical signals into electrical signals 194 and transmits them to the second remote radio device 151D. For example, the second remote radio device 151D may also be a remote radio unit (RRU). The remote radio unit 151D converts the electrical signals 194 into terminal signals, which are then used by at least one second antenna 153D to transmit and receive these terminal signals. This terminal signal may be a millimeter wave high frequency signal.

[0072] It should be noted that, Figure 5The wireless radio frequency conversion system 100D shown can be a bidirectional transmission system. For example, at least one second antenna 153D receives radio frequency millimeter waves and generates a radio frequency millimeter wave signal. A second remote wireless device 151D receives the radio frequency millimeter wave signal and generates an electrical signal 195. Then, the second remote wireless device 151D transmits the electrical signal 195 to a second conversion device 140D, which converts the electrical signal 195 into an optical signal and transmits it through an optical fiber 130D to a first conversion device 120D. Subsequently, the first conversion device 120D converts the optical signal into an electrical signal 196 and transmits it to the first remote wireless device 113D.

As shown, the wireless radio frequency transceiver 110E includes at least one first antenna 111E and a radio front-end signal processor 113E. The wireless radio frequency transmission device 150E includes a radio frequency transceiver 151E.

[0075] In operation, at least one first antenna 111E is used to transmit and receive radio frequency (RF) signals. Subsequently, a radio front-end signal processor 113E receives the RF signals and performs front-end signal processing to generate a data signal. Next, the data signal is transmitted to an RF transceiver 151E via a first conversion device 120E, an optical fiber 130E, and a second conversion device 140E. Finally, the RF transceiver 151E receives the data signal, converts it from an analog signal to a digital signal to generate a terminal signal, and transmits the converted terminal signal. At this point, the terminal signal is a digital signal. For example, at least one first antenna 111E transmits and receives RF millimeter-wave signals, and the radio front-end signal processor (RFFE) 113E performs front-end processing such as filtering and switching on the RF millimeter-wave signals to generate a data signal. The data signal can be an electrical signal such as a communication signal 191, a control signal 192, or a resonant signal 193, etc. The communication signal 191 can be a millimeter-wave high-frequency signal or an intermediate-frequency signal.

[0076] Next, the radio front-end signal processor 113E transmits the aforementioned communication signal 191, control signal 192, or resonant signal 193, etc., electrical signals to the first conversion device 120E. The first conversion device 120E converts these electrical signals into optical signals and transmits them to the second conversion device 140E via optical fiber 130E. The optical fiber 130E may contain one or more optical fibers to facilitate the transmission of the optical signal between the first conversion device 120E and the second conversion device 140E. Subsequently, the second conversion device 140E converts the optical signal into an electrical signal 194 and transmits it to the radio frequency transceiver 151E. The radio frequency transceiver 151E converts the millimeter-wave high-frequency signal or intermediate frequency signal into digital signals such as backhaul signals or IQ modulation signals, and then transmits them to the baseband unit (BBU).

[0077] It should be noted that, Figure 6 The wireless radio frequency conversion system 100E shown can be a bidirectional transmission system. For example, when the radio frequency transceiver 151E receives an IQ frequency modulation signal from the baseband unit, the radio frequency transceiver 151E converts the IQ frequency modulation signal into an electrical signal 195. Then, the radio frequency transceiver 151E transmits the electrical signal 195 to the second conversion device 140E, which converts the electrical signal 195 into an optical signal and transmits it through the optical fiber 130E to the first conversion device 120E. Subsequently, the first conversion device 120E converts the optical signal into an electrical signal 196 and transmits it to the radio front-end signal processor 113E. It should be noted that this application does not... Figure 6 The embodiments shown are limited and are merely illustrative of one implementation of this case.

As shown, the wireless radio frequency transceiver 110F includes at least one first antenna 111F and a remote wireless device 113F. The wireless radio frequency transmission device 150F includes a processor 151F.

[0079] Operationally, at least one first antenna 111F is used to transmit and receive radio frequency (RF) signals. Subsequently, a remote wireless device 113F receives the RF signals and generates data signals. Next, the data signals are transmitted to a processor 151F via a first conversion device 120F, an optical fiber 130F, and a second conversion device 140F. Finally, the processor 151F receives the data signals, processes them to generate a terminal signal, and transmits the terminal signal, which can be a digital signal. For example, the remote wireless device 113F can be a Remote Radio Unit (RRU), which transmits and receives RF millimeter-wave signals via at least one first antenna 111F, and then amplifies, filters, switches, etc., the RF millimeter-wave signals to generate data signals. These data signals can be communication signals 191, control signals 192, or resonant signals 193, etc., and other electrical signals. The communication signal 191 can be a millimeter-wave high-frequency signal, an intermediate frequency (IF) signal, a backhaul signal, or an IQ-modulated signal.

[0080] Next, the remote wireless device 113F transmits the aforementioned communication signal 191, control signal 192, or resonant signal 193, etc., electrical signals to the first conversion device 120F. The first conversion device 120F converts these electrical signals into optical signals and transmits them through optical fiber 130F to the second conversion device 140F. The optical fiber 130F may contain one or more optical fibers to facilitate the transmission of the optical signal between the first conversion device 120F and the second conversion device 140F. Subsequently, the second conversion device 140F converts the optical signal into an electrical signal 194 and transmits it to the processor 151F. For example, the processor 151F may be a baseband processing unit (BBU), a centralized unit (CU), or a distributed unit (DU). The processor 151F processes the electrical signal 194 to convert it into a terminal signal and transmit it to the backhaul network.

[0081] It should be noted that, Figure 7 The wireless radio frequency conversion system 100F shown can be a bidirectional transmission system. For example, when the processor 151F receives an electrical signal from the backhaul network, the processor 151F converts it into an electrical signal 195. Then, the processor 151F transmits the electrical signal 195 to the second conversion device 140F, which converts the electrical signal 195 into an optical signal and transmits it through the optical fiber 130F to the first conversion device 120F. Subsequently, the first conversion device 120F converts the optical signal into an electrical signal 196 and transmits it to the remote wireless device 113F.

[0082] In one embodiment, the wireless radio frequency conversion system 100F further includes a radio frequency transceiver, which can be located in the remote wireless device 113F or in the processor 151F, depending on the actual needs.

The optical splitter / combiner 125G is coupled to the optical isolator 124G and the second multiplexer 126G. In operation, the drivers 121G1~121Gn receive data signals T1~Tn. The drivers 121G1~121Gn drive the photoelectric converters 122G1~122Gn according to the data signals T1~Tn to generate multiple optical signals λ1~λn of different wavelengths. The first multiplexer 123G receives the multiple optical signals λ1~λn and combines the multiple optical signals λ1~λn to generate a combined optical signal λ1~λn. Optical isolator 124G allows only the combined optical signals λ1~λn from the first multiplexer 123G to pass through, while blocking the combined optical signals λ1~λn transmitted by the optical splitter-combiner 125G. In other words, optical isolator 124G can only transmit in one direction. Subsequently, optical splitter-combiner 125G transmits the combined optical signals λ1~λn to optical fiber 130G.

[0085] On the other hand, the optical splitter / combiner 125G receives the combined optical signals λ1~λn from the optical fiber 130G and transmits them to the second multiplexer 126G and the optical isolator 124G. The second multiplexer 126G then distributes the combined optical signals λ1~λn into multiple optical signals λ1~λn of different wavelengths. If the optical splitter / combiner 125G attempts to transmit the combined optical signals λ1~λn to the transmission path on the right, it will be blocked by the optical isolator 124G. Next, the photodetectors 127G1~127Gn detect the multiple optical signals λ1~λn and generate multiple data signals R1~Rn based on them.
