Description

Optical fiber transmission system

The present invention relates to a video transmission system, and in particular to an optical fiber transmission system.

In the operation of hospitals, surgery has become the hospital's main source of income. In order to improve the quality of surgeries, various hospitals have invested considerable costs in purchasing sophisticated operating room instruments/equipment.

Generally speaking, when doctors perform operations, they often use auxiliary medical video systems (such as endoscope systems, surgical navigation systems, vascular photography systems, Da Vinci robots, etc.). In order to achieve better auxiliary effects, the above-mentioned medical video systems Most systems need to meet requirements such as high transmission speed, high immediacy, long-distance transmission, low attenuation, good quality and mutual transmission.

However, in the existing technology, the system architecture used to transmit the video captured by the video source (such as an endoscope) to a screen that can be viewed by doctors not only has a more complex transfer relationship, but also easily causes a delay in video transmission. This increases the risk of surgery.

Therefore, it is difficult for those skilled in the art to design a low-complexity High-speed, low-latency medical video transmission architecture is indeed an important issue.

Please refer to FIG. 1A , which is a conventional mechanism used for medical video transmission. In FIG. 1A , it is assumed that the video source 110 is an endoscope that can provide High Definition Multimedia Interface (HDMI) video, and the display 170 can be used to allow the doctor to view the screen of the video captured by the endoscope. For ease of explanation, it is assumed below that the display 170 can receive video signals through a Serial Digital Interface (SDI) (ie, the video source 110 and the display 170 correspond to different video standards).

Generally speaking, in order for the display 170 to successfully display the video captured by the video source 110, the optical transmitter 120, the optical receiver 130, the optical transmitter 150 and the optical receiver need to be disposed in sequence between the video source 110 and the display 170. Device 160.

In this case, when the video source 110 obtains video (for example, endoscopic video) through shooting, the corresponding electrical signal E1 can be provided to the optical transmitter 120 , and the optical transmitter 120 can correspondingly transmit the electrical signal E1 Convert it into an optical signal OP1, and send the optical signal OP1 to the optical receiver 130.

In the scenario of FIG. 1A , since the video source 110 is assumed to be used to provide HDMI video, the designer can pre-connect the optical receiver 130 corresponding to the video source 110 to the electrical matrix 140 when building the operating room environment. on the HDMI input. Therefore, after the optical receiver 130 receives the optical signal OP1, the optical signal OP1 can be converted into the electrical signal E2, and the electrical signal E2 can be output to the input terminal corresponding to HDMI on the electrical matrix 140. In other examples, if the video source 110 is used to provide digital visual interface (Digital Visual Interface, DVI) video or display port (display port, DP) video, the designer can change the optical receiver 130 to be connected to the input terminal corresponding to DVI or DP on the electrical matrix 140.

In the above example, since the display 170 is assumed to correspond to the SDI standard, its corresponding optical transmitter 150 can be pre-connected by the designer to the output end of the electrical matrix 140 corresponding to SDI. In this case, when the electrical matrix 140 receives the electrical signal E2, it may convert it into the electrical signal E3 corresponding to the SDI standard, and provide the electrical signal E3 to the optical transmitter 150.

Afterwards, the optical transmitter 150 can convert the electrical signal E3 into the optical signal OP2, and provide the optical signal OP2 to the optical receiver 160. Accordingly, the light receiver 160 can convert the optical signal OP2 into the electrical signal E4, and provide the electrical signal E4 to the display 170, so that the display 170 can display the video captured by the video source 110.

It can be seen from FIG. 1A that in the architecture shown, a set of optical transmitters/optical receivers need to be provided for the video source 110 and the display 170 respectively, so a total of two sets of optical transmitters/optical receivers need to be provided. Moreover, the signal source connectors corresponding to different video standards are also different. Therefore, in addition to the higher cost and complicated transfer relationship of this approach, multiple optical/electrical signal conversions will also bring corresponding delays.

In addition, in order for the electrical matrix 140 to convert the electrical signal E2 corresponding to the HDMI standard into the electrical signal E3 corresponding to the SDI standard, the electrical matrix 140 also needs to perform relatively complex operations.

Please refer to FIG. 1B , which is based on the electrical matrix architecture shown in FIG. 1A . In FIG. 1B , when the electrical matrix 140 receives the electrical signal E2 from the input terminal corresponding to the HDMI standard, it needs to first decode the electrical signal E2 into raw data at the RGB level. data), the original data can be encoded into the electrical signal E3 corresponding to the SDI standard through the image processor 141 of the electrical matrix 140. In this case, the above-mentioned conversion operation performed by the electrical matrix 140 will also introduce other delays. Moreover, since the electrical matrix 140 costs tens of thousands of dollars, the implementation cost of the architecture of FIG. 1A remains high.

In addition, it has been measured that the architecture of FIG. 1A will cause a delay of about 0.3 seconds in the picture viewed by the physician from the display 170 . In this case, assuming that it takes 10 minutes for the video source 110 to enter the stomach from the patient's mouth, this will cause a total delay of 3.3 minutes in the image viewed by the physician on the display 170, thereby correspondingly increasing the risk of surgery.

In view of this, the present invention provides an optical fiber transmission system, which can be used to solve the above technical problems.

The invention provides an optical fiber transmission system, which includes a first optical transmitter, an optical fiber matrix and a first optical receiver. The first optical transmitter receives a first video electrical signal corresponding to a first video standard and converts the first video electrical signal into a first optical signal with a designated transmission rate. The optical fiber matrix is connected to the first optical transmitter and used for receiving and transmitting the first optical signal. The first optical receiver is connected to the optical fiber matrix, receives the first optical signal with a specified transmission rate transmitted by the optical fiber matrix, and converts the first optical signal into a second video telecommunication signal corresponding to a second video standard. .

In view of this, the present invention proposes a novel optical fiber transmission system, which can be used to solve the above technical problems.

Please refer to FIG. 2 , which illustrates a multi-interface direct-to-optical fiber transmission system according to an embodiment of the present invention. As shown in Figure 2, the optical fiber transmission system 200 includes an optical transmitter 210 and an optical receiver 220. The optical transmitter 210 can be connected between the video source 201 and the optical receiver 220, and the optical receiver 220 can be connected to the display 202. .

In an embodiment of the present invention, the video source 201 may correspond to the first video beacon. standard, and the display 202 may correspond to the second video standard. In different embodiments, the first video standard may be the same as or different from the second video standard. In some embodiments, the first video standard corresponding to the video source 201 may be one of the HDMI standard, DVI standard, DP standard and SDI, for example, but it may not be limited thereto. In addition, the second video standard corresponding to the display 202 may also be one of the HDMI standard, DVI standard, DP standard and SDI, but is not limited thereto.

In one embodiment, after the video source 201 (such as an endoscope) is photographed and generates the corresponding video signal ES1, the video signal ES1 can be transmitted to the optical transmitter 210.

Accordingly, after the optical transmitter 210 receives the video electrical signal ES1, the optical transmitter 210 can convert the video electrical signal ES1 into an optical signal OS1 with a specified transmission rate, and transmit the optical signal OS1 to the optical receiver 220. In some embodiments, the optical transmitter 210 can losslessly convert the video electrical signal ES1 into an optical signal OS1 with a specified transmission rate. That is, the optical transmitter 210 can convert the video electrical signal ES1 into the optical signal OS1 with a specified transmission rate without compression, but is not limited thereto.

In different embodiments, the above specified transmission rate may range from 9.984Gbps to 10.2Gbps. In a preferred embodiment, the above specified transmission rate may be 10Gbps, but it is not limited to this.

After the optical receiver 220 receives the optical signal OS1 with the above specified transmission rate from the optical transmitter 210, the optical receiver 220 can convert the optical signal OS1 into the video electrical signal ES2 corresponding to the second video standard, and convert the video electrical signal ES2 output to the display 202 corresponding to the second video standard. Thereby, the display 202 can present the picture captured by the video source 201 .

Furthermore, since the optical transmitter 210 is designed to convert the video electrical signal ES1 corresponding to the first video standard into the optical signal OS1 with a specified transmission rate, and the optical receiver 220 is correspondingly designed to convert the The optical signal OS1 with a specified transmission rate is converted into a video electrical signal ES2 corresponding to the second video standard. Therefore, even if the video source 201 and the display 202 correspond to different video standards, the optical signal OS1 provided by the optical transmitter 210 can be It is directly transmitted to the optical receiver 220 without any conversion.

It can be seen from the above that compared with the electrical matrix and two sets of optical transmitter/optical receiver architecture in Figure 1A, Figure 2 can only set up a set of optical transmitter 210/optical receiver between the video source 201 and the display 202. In the case of the processor 220, the same video transmission function as the architecture of Figure 1A is implemented. Moreover, in addition to having lower complexity, the switching relationship of the architecture in Figure 2 can also achieve lower latency by reducing the number of optical/electrical signal conversions.

It has been measured that the delay generated by the architecture in Figure 2 is about 2μs, which is only one 150,000th of the architecture in Figure 1A. Moreover, the implementation cost of Figure 2 is much lower than the architecture of Figure 1A without the need to set up an electrical matrix that costs tens of thousands of dollars.

Please refer to FIG. 3A , which is an architectural diagram of an optical transmitter and an optical receiver according to an embodiment of the present invention. In the scenario of FIG. 3A , it is assumed that the first video standard corresponding to the video source 201 is the HDMI standard or the DVI standard, and the second video standard corresponding to the display 202 is assumed to be the HDMI standard or the DVI standard. In this case, the video electrical signal ES1 provided by the video source 201 is, for example, a minimum transmission difference (Transition Minimized Differential Signaling, TMDS) signal (hereinafter referred to as the first TMDS signal).

As shown in FIG. 3A , the optical transmitter 210 includes a first TMDS transceiver (transceiver) 311 , a serializer 312 (serializer), an optical transceiver 313 and a controller 314 . In some embodiments, the first TMDS transceiver 311 can receive and clean the noise in the first TMDS signal (ie, the video electrical signal ES1) from the video source 201. Afterwards, the serializer 312 coupled to the first TMDS transceiver 311 can receive the cleaned first TMDS signal ES1' and serialize it into the first serial signal TS1. In some embodiments, the serializer 312 may be configured to only output serial signals with the specified transmission rate described above. In this case, no matter what quality video signal the video signal ES1 corresponds to, the serializer 312 will correspondingly generate a serial signal with the above specified transmission rate, but it is not limited thereto. Then, the optical transceiver 313 coupled to the serializer 312 can convert the first serial signal TS1 into an optical signal OS1 with a specified transmission rate. In FIG. 3A , the optical transmitter 210 can send the optical signal OS1 to the optical receiver 220 through the optical fiber 330 connected between the optical transmitter 210 and the optical receiver 220 .

In different embodiments, the above-mentioned operations performed by the first TMDS transceiver 311, the serializer 312, and the optical transceiver 313 can all be performed by coupling the first TMDS transceiver 311, the serializer 312, and the optical transceiver 313.

In some embodiments, the optical transceiver 321 can receive the optical signal OS1 from the optical transceiver 313 through the optical fiber 330, and convert the optical signal OS1 into the second serial signal TS2. Afterwards, the deserializer 322 coupled to the optical transceiver 321 can deserialize the second serial signal TS2 from the optical transceiver 321 into a second TMDS signal ES2'. Then, the second TMDS transceiver 323 coupled to the deserializer 322 can receive and clean the noise in the second TMDS signal ES2', and use the cleaned second TMDS signal ES2' as the video electrical signal ES2. Output to display 202.

In different embodiments, the above-mentioned operations performed by the optical transceiver 321, the deserializer 322, and the second TMDS transceiver 323 can be performed by coupling the optical transceiver 321, the deserializer 322, and the second TMDS transceiver. The controller 324 of the device 323 controls the execution of the optical transceiver 321, the deserializer 322, and the second TMDS transceiver 323 through corresponding control signals, but it is not limited to this.

Please refer to FIG. 3B , which is an architectural diagram of an optical transmitter and an optical receiver according to an embodiment of the present invention. In the scenario of FIG. 3B , it is assumed that the first video standard corresponding to the video source 201 is the SDI standard or the DP standard, and the second video standard corresponding to the display 202 is assumed to be the SDI standard or the DP standard.

As shown in FIG. 3B , the optical transmitter 210 includes a first HDMI circuit 315 , a serializer 312 , an optical transceiver 313 and a controller 314 . In some embodiments, the first The HDMI circuit 315 can receive the video electrical signal ES1 and convert the video electrical signal ES1 into the first HDMI signal HS1. Afterwards, the serializer 312 coupled to the first HDMI circuit 315 can receive the first HDMI signal HS1 and serialize it into the first serial signal TS1. In some embodiments, the serializer 312 may be configured to only output serial signals with the specified transmission rate described above. In this case, no matter what quality video signal the video signal ES1 corresponds to, the serializer 312 will correspondingly generate a serial signal with the above specified transmission rate, but it is not limited thereto. Then, the optical transceiver 313 coupled to the serializer 312 can convert the first serial signal TS1 into an optical signal OS1 with a specified transmission rate. In FIG. 3B , the optical transmitter 210 can send the optical signal OS1 to the optical receiver 220 through the optical fiber 330 connected between the optical transmitter 210 and the optical receiver 220 .

In different embodiments, the above-mentioned operations performed by the first HDMI circuit 315, the serializer 312, and the optical transceiver 313 can be controlled by the controller coupled to the first HDMI circuit 315, the serializer 312, and the optical transceiver 313. The controller 314 controls the execution of the first HDMI circuit 315, the serializer 312, and the optical transceiver 313 through corresponding control signals, but it is not limited to this. In some embodiments, the controller 314 can enable the optical transceiver 313 accordingly after the first HDMI circuit 315 and the serializer 312 complete initialization, thereby preventing the optical transceiver 313 from accidentally sending meaningless data to Light receiver 220, but may not be limited to this.

As shown in FIG. 3B , the optical receiver 220 may include an optical transceiver 321 , a deserializer 322 , a second HDMI circuit 325 and a controller 324 . In some embodiments, the optical transceiver 321 can receive the optical signal OS1 from the optical transceiver 313 through the optical fiber 330, and convert the optical signal OS1 into the second serial signal TS2. Afterwards, the deserializer 322 coupled to the optical transceiver 321 can deserialize the second serial signal TS2 from the optical transceiver 321 into the second HDMI signal HS2. Then, the second HDMI circuit 325 coupled to the deserializer 322 can receive the second HDMI signal HS2, convert the second HDMI signal HS2 into the video electrical signal ES2, and output it to the display 202.

In different embodiments, the above-mentioned operations performed by the optical transceiver 321, the deserializer 322, and the second HDMI circuit 325 can be performed by coupling the optical transceiver 321, the deserializer 322, and the second HDMI circuit 325. The controller 324 controls the execution of the optical transceiver 321, the deserializer 322, and the second HDMI circuit 325 through corresponding control signals, but it is not limited to this.

In other embodiments, according to the first video standard corresponding to the video source 201 and the second video standard corresponding to the display 202, the optical transmitter 210 of FIG. 3A can be arbitrarily combined with the optical receiver 220 of FIG. 3A or the optical receiver 220 of FIG. 3B. of optical receiver 220. Similarly, the optical transmitter 210 of FIG. 3B can also be used optionally with the optical receiver 220 of FIG. 3A or the optical receiver 220 of FIG. 3B.

For example, assuming that the video source 201 and the display 202 correspond to the HDMI standard and the SDI standard respectively, the video source 201 can be connected to the display 202 through the optical transmitter 210 of Figure 3A, the optical fiber 330 and the optical receiver 220 of Figure 3B in sequence. . For another example, assuming that the video source 201 and the display 202 correspond to the SDI standard and the HDMI standard respectively, the video source 201 can be connected to the optical transmitter 210 in sequence through the optical transmitter 210 in Figure 3B, the optical fiber 330 and the optical receiver 220 in Figure 3A. Display 202. As another example, assume that the video source 201 and the display 202 correspond to the DP standard and the DVI standard respectively. If so, the video source 201 can be connected to the display 202 through the optical transmitter 210 of FIG. 3B, the optical fiber 330, and the optical receiver 220 of FIG. 3A in sequence.

In addition, in some embodiments, the present invention further proposes an optical fiber matrix, which can be used to route optical signals between multiple sets of video sources and displays, thereby realizing more diverse video transmission mechanisms, as detailed below.

Please refer to FIG. 4 , which is a schematic diagram of an optical fiber transmission system according to an embodiment of the present invention. In FIG. 4 , the optical fiber transmission system 400 includes an optical transmitter 210 , an optical receiver 220 and an optical fiber matrix 410 . For details of the optical transmitter 210 and the optical receiver 220 , reference can be made to the descriptions in previous embodiments and will not be discussed further here. Repeat.

As shown in FIG. 4 , the optical fiber matrix 410 may include a plurality of input terminals I1 to I4, a plurality of output terminals O1 to O4, a controller 411 and a communication circuit 412. For ease of explanation, it is assumed below that the optical transmitter 210 is connected to the input terminal I1 and the optical receiver 220 is connected to the output terminal O2, but it is not limited to this.

In one embodiment, since the display 202 is assumed to be used to display the video captured by the video source 201, a first correspondence can be configured between the input terminal I1 and the output terminal O2 corresponding to the video source 201 and the display 202. relation. In this case, the controller 411 can switch the input terminal I1 to the output terminal O2 according to the first corresponding relationship between the input terminal I1 and the output terminal O2.

Therefore, after the optical transmitter 210 sends the optical signal OS1 with the above specified transmission rate to the input terminal I1, the input terminal I1 can directly transfer the optical signal OS1 to the output terminal O2, and the output terminal O2 can correspondingly transmit the optical signal OS1 to the input terminal I1. OS1 outputs to optical receiver 220.

In other words, after the optical fiber matrix 410 receives the optical signal OS1 from the optical transmitter 210 through the input terminal I1, it can directly transmit the optical signal OS1 through the output terminal O2 corresponding to the input terminal I1 without performing any processing/conversion on the optical signal OS1. The optical signal OS1 is output to the optical receiver 220. Therefore, compared with the electrical matrix 140 of FIG. 1A , the optical fiber matrix 410 of FIG. 4 can complete signal transmission with a lower delay.

Moreover, compared with the electrical matrix 140 which is usually priced at tens of thousands of US dollars, the optical fiber matrix 410 only costs about a few thousand US dollars, so the implementation cost is also much lower than that of the electrical matrix 140 .

In some embodiments, the designer can remotely set the corresponding relationship between the input terminals I1 ~ I4 and the output terminals O1 ~ O4 through the network. For example, after deciding that the input terminal I1 needs to correspond to the output terminal O2, the designer can run the control software corresponding to the optical fiber matrix 410 on the computer device he or she operates, and edit the input terminals I1 and O2 on the control software. The first correspondence between the output terminals O2. After completing the setting of the first corresponding relationship, the computer device can send the corresponding configuration signal CS to the optical fiber matrix 410 through the network.

Correspondingly, the communication circuit 412 coupled to the controller 411 can receive the configuration signal CS from the network, and the controller 411 can obtain the first corresponding relationship between the input terminal I1 and the output terminal O2 based on the configuration signal CS, and then based on this The first corresponding relationship switches the input terminal I1 to the output terminal O2.

In other embodiments, the optical fiber matrix 410 may also provide a control panel for the designer to manually set the corresponding relationship between the input terminals I1 ~ I4 and the output terminals O1 ~ O4. In some embodiments, the above-mentioned control panel may include corresponding input terminals I1 to I4 and input terminals I1 to I4. Multiple LED buttons at output terminals O1~O4. Based on this, after deciding that the input terminal I1 needs to correspond to the output terminal O2, the designer can find the LED button corresponding to the input terminal I1 (hereinafter referred to as the first LED button) on the control panel, and find A light-emitting diode button corresponding to the output terminal O2 is output (hereinafter referred to as the second light-emitting diode button).

After that, the designer can set the first LED button to correspond to the second LED button, and the controller 411 can obtain the first corresponding relationship between the input terminal I1 and the output terminal O2 accordingly, and then according to This first corresponding relationship switches the input terminal I1 to the output terminal O2, but it is not limited to this.

In other embodiments, fiber optic matrix 410 may provide more complex routing functions, the details of which are detailed below.

Please refer to FIG. 5 , which is a schematic diagram of the optical fiber transmission system shown in FIG. 4 . As shown in Figure 5, the optical fiber transmission system 500 includes an optical transmitter 210, an optical receiver 220, an optical receiver 220', an optical transmitter 510, an optical receiver 520 and an optical fiber matrix 410.

In FIG. 5 , in addition to the first corresponding relationship between the input terminal I1 and the output terminal O2 , a second corresponding relationship between the input terminal I1 and the output terminal O1 may also be configured. In this case, the controller 411 can switch the input terminal I1 to the output terminal O1 according to the second corresponding relationship. In other words, the input terminal I1 can be connected to the output terminals O1 and O2 at the same time.

Based on this, after the optical transmitter 210 sends the optical signal OS1 with the above specified transmission rate to the input terminal I1, the input terminal I1 can directly transfer the optical signal OS1 to the output terminals O1 and O2. Correspondingly, the output terminal O1 can output the optical signal OS1 to the optical receiver 220' connected to the output terminal O1, and the output terminal O2 can output the optical signal OS1. OS1 outputs to the optical receiver 220 connected to the output terminal O2.

After the optical receiver 220' receives the optical signal OS1, operations similar to the optical receiver 220 can be performed to convert the optical signal OS1 into a video electrical signal ES2' for the display 202' to present the video captured by the video source 201. .

In the context of Figure 5, the display 202' may correspond to a third video standard, and the third video standard may be the same as or different from the first video standard and the second video standard. For example, assuming that the first video standard and the second video standard are the HDMI standard and the SDI standard respectively, the third video standard may be any one of the HDMI standard, the SDI standard, the DP standard and the DVI standard. Accordingly, the optical receiver 220' can be used to convert the optical signal OS1 into a video electrical signal ES2' corresponding to the third video standard for presentation by the display 202'.

In short, the optical fiber matrix 410 can broadcast the optical signal OS1 from the optical transmitter 210 to the output terminals O1 and O2 based on the above-mentioned first correspondence relationship and the second correspondence relationship, so that the corresponding displays 202 and 202' can The video image captured by the video source 201 can be presented, but is not limited to this.

In addition, assuming that the display 502 can be used to display the video captured by the video source 501, the designer can connect the corresponding optical transmitter 510 and the optical receiver 520 to the selected input terminal (such as the input terminal I2) and the output terminal respectively. After the terminal (for example, the output terminal O4), a third corresponding relationship between the input terminal I2 and the output terminal O4 is established. In this case, the controller 411 can switch the input terminal I2 to the output terminal O4 according to the third corresponding relationship between the input terminal I2 and the output terminal O4.

In one embodiment, the video source 501 may correspond to the fourth video standard, and The display 502 may correspond to the fifth video standard. In different embodiments, the fourth video standard may be the same as or different from the fifth video standard. In some embodiments, the fourth video standard corresponding to the video source 501 may be one of the HDMI standard, DVI standard, DP standard and SDI, for example, but it may not be limited thereto. In addition, the fifth video standard corresponding to the display 502 may also be one of the HDMI standard, DVI standard, DP standard and SDI, but is not limited thereto.

In one embodiment, after the video source 501 is photographed to generate the corresponding video signal ES1a, the video signal ES1a can be transmitted to the optical transmitter 510.

Accordingly, after the optical transmitter 510 receives the video electrical signal ES1a, the optical transmitter 510 can convert the video electrical signal ES1a into the optical signal OS1a with the above specified transmission rate, and transmit the optical signal OS1a to the input terminal I2. Afterwards, the input terminal I2 of the optical fiber matrix 410 can directly transmit the optical signal OS1a to the output terminal O4, and the output terminal O4 can correspondingly output the optical signal OS1a to the optical receiver 520.

After the optical receiver 520 receives the optical signal OS1a with the above specified transmission rate from the output terminal O4, the optical receiver 520 can convert the optical signal OS1a into the video electrical signal ES2a corresponding to the fifth video standard, and convert the video electrical signal ES2a Output to the display 502 corresponding to the fifth video standard. Thereby, the display 502 can present the picture captured by the video source 501 .

It can be seen from the above that after the optical fiber matrix 410 receives the optical signal OS1a from the optical transmitter 510 through the input terminal I2, it can also directly transmit the optical signal OS1a through the output corresponding to the input terminal I2 without performing any processing/conversion on the optical signal OS1a. Terminal O4 outputs the optical signal OS1a to the optical receiver 520, and the delay of this process is also much lower than that of Figure 1A electrical matrix 140.

In other embodiments, designers can freely configure other combinations of video sources/displays/optical transmitters/optical receivers according to the concepts taught in FIG. 5 , and are not limited to the aspects shown in FIG. 5 .

In addition, although the optical fiber matrix 410 is shown in FIG. 4 and FIG. 5 as including four input terminals I1 to I4 and four output terminals O1 to O4, the implementation of the present invention may not be limited thereto. In other embodiments, those skilled in the art can adjust the fiber optic matrix 410 to have any number of input terminals and output terminals as required.

To sum up, in the optical fiber transmission system proposed by the present invention, the optical transmitter is designed to convert the video electrical signal received from the video source into an optical signal with a specified transmission rate. Correspondingly, the optical receiver is also designed to convert the optical signal with a specified transmission rate into a video electrical signal corresponding to the video standard, so that the display can present the picture captured by the video source. Therefore, even if the video source and the display correspond to different video standards, the optical signal provided by the optical transmitter can be directly transmitted to the optical receiver without any conversion. In this way, the process of (medical) video transmission can be effectively simplified, thereby reducing cost, delay and complexity.

In addition, by arranging an optical fiber matrix in the optical fiber transmission system, multiple optical signals (all with the above specified transmission rates) can be routed between multiple sets of video sources/displays. Moreover, since the optical fiber matrix simply transmits optical signals between the corresponding input terminals and output terminals, no additional signal processing/conversion is required, so it can effectively reduce the delay caused by routing. , which can be realized at a lower cost.
