[Embodiment] In order to make the above objects, features and advantages of the present invention more apparent, the following detailed description of the preferred embodiment The description is as follows: Figure 1 is a block diagram of data transmission between a host and a device in the prior art, wherein the host 120 can be a fast peripheral component interconnect standard (pciE) interface specification or a universal serial bus version 3.0 (USB3). .0) interface specification, etc., a high-speed electronic transceiver that supports hot-swap function. The host 12 polls whether or not a device is inserted at regular intervals. When the device 150 is detected to be inserted, the host 120 initiates An iink training sequence is transmitted to establish a link with the device 150. When the door is used, the device 150 also polls the host for existence at regular intervals. When the host 120 is present, a link training sequence is also initiated to establish a link with the host 120. VIC 10-0011100-TW/0608-A42664TWf 5 201203888 The host 120 is coupled to the device 150 as shown in FIG. It is shown that the positive transmitting signal terminal TX+ and the negative transmitting signal terminal TX- of the host 120 are coupled to the positive receiving signal terminal RX+ and the negative receiving signal terminal RX- of the device 150, so that the host 120 transmits the data to the device 150, and the data may be A differential signal pair is sent in the form; the positive receiving signal terminal RX+ and the negative receiving signal terminal RX- of the host 120 are coupled to the positive transmitting signal terminal TX+ and the negative transmitting signal terminal TX- of the device 150, so as to be implemented by the device 150 to the host 120. The data may be sent in the form of a differential signal pair. The host 120 determines whether the differential terminator impedance is coupled between the positive transmitting signal terminal TX+ and the negative transmitting signal terminal TX- by polling the differential terminator impedance. Whether there is a device end insertion. When the device 150 is coupled to the host 120 as shown in FIG. 1 and is ready, there is a differential termination impedance 112 between the positive receiving signal terminal RX+ and the negative receiving signal terminal RX- of the device 150. In an embodiment, the positive receiving signal terminal RX+ and the negative receiving signal terminal RX- of the device 150 are both coupled to a ground limit to achieve a differential termination impedance 112. The host detects that it is transmitting a signal. A differential termination impedance occurs between the terminal TX+ and the negative transmission signal terminal TX-, that is, when the presence of the differential termination impedance 112 is detected, it is considered that there is a device end insertion, so the host 120 initiates transmission of a link training sequence. The device 150 also polls whether there is a differential termination impedance 113 between the positive transmitting terminal TX+ and the negative transmitting terminal TX- to determine whether it is coupled to the host 120. In one embodiment, the positive receiving signal terminal RX+ and the negative receiving signal terminal RX_ of the host 120 are evenly connected to a grounding terminal to achieve a differential termination impedance 113. When the device 150 detects that there is a differential termination impedance 113 between its positive transmitting signal terminal TX+ and the negative transmitting signal terminal TX-, the device 150 also sends a response signal to the host 120 'the main VIC10-001 ll〇〇-TW/0608 -A42664TWf 6 201203888 When the machine 120 receives the response signal, the link training sequence is successfully established, and the host and the device 150 are normally linked for data transmission. In one embodiment, the response signal is a low frequency periodic signal (L〇w Frequency PeH〇dic Signal) with a period ranging from 2〇_1〇〇ns. However, in some applications, for example, when the host and the device are respectively coupled to the optical transceiver module for photoelectric conversion, data transmission through the optical fiber may cause problems, which will be described in detail below. Figure 2 shows a block diagram of the > material transfer between the host and the device via the optical transceiver component. In one embodiment, the light-receiving component is an active optical cable (AOC). As shown in Fig. 2, the optical transceiver unit 230 includes an optical transceiver module 201, an optical transceiver module 203, and an optical fiber 205. In order to make the illustration clear and convenient for description, only the electrical connection of the data transmission between the host 210 and the device 250 is shown in FIG. 2, and the optical transmission in the optical transceiver module 201 and the optical transceiver module 203 is not indicated. Components such as a laser diode and a photodiode. The above optical passive component is used to convert between an electrical signal and an optical signal. In the second embodiment, the positive transmitting signal terminal Τχ+ and the negative transmitting signal terminal ΤΧ of the host 210 are coupled to a first transmitting pair τ+/Τ- of the optical transceiver module 201, and the optical transceiver module 201 is coupled to the host. 210, configured to convert an electrical signal emitted by the host 210 into an optical signal. The optical fiber 205 is coupled to the optical transceiver module 201 and the optical transceiver module 203 for performing optical transmission between the two optical transceiver modules 2〇1 and the optical transceiver module 203. The optical transceiver module 203 is coupled to the device 250 for converting the optical signal into an electrical signal. The second receiving pair R+/R- of the optical transceiver module 203 is provided to the positive receiving terminal rx+ and the negative receiving of the device 250. Signal terminal RX-, for data transmission. When one end of the optical transceiver module 230 (the end of the optical transceiver module 201) VIC10-001 lI00-TW/0608-A42664TWf 7 201203888 is coupled to the host 210, the optical transceiver module 201 includes an internal fixed resistor. 207 and resistor 209 are coupled to the first transmit pair T+/T- of the optical transceiver module 201, and the host 210 detects that a differential termination impedance occurs between the positive transmit signal terminal TX+ and the negative transmit signal terminal TX-. 'I immediately think that there is a device plugged in, so it will initiate a transfer - key gentleman training sequence. However, when the other end of the optical transceiver component 230 is not lightly connected to the device 250, the link training sequence will fail to be established, and the host 21 will enter an abnormal working mode. In the abnormal working mode, the host 21 cannot perform data transmission with the device 250, nor can it jump out from the above abnormal mode. The host can re-monitor whether a device is connected only after the host is reset. In one embodiment, the abnormal mode of operation is a standard compliance mode in which the integrity of the signal sent by the host 210 is tested. On the other hand, in the second figure, the positive transmitting signal terminal τχ+ of the device 250 and the negative transmitting signal terminal TX- are coupled to a second transmitting pair T+/T_' optical transceiver module 203 of the optical transceiver module 203. Connected to device 250 for converting an electrical signal emitted by device 250 into an optical signal. The optical fiber 206 consumes the optical transceiver module 2〇1 and the optical transceiver module 203' for performing optical transmission between the two optical transceiver modules 2〇1 and the optical transceiver module 203. The optical transceiver module 201 is connected to the host 21A, and is configured to convert the optical ## into an electrical signal. The first receiving pair R+/R- of the optical transceiver module 2〇1 is provided to the receiving signal end of the host 210. Rx+ and negative receiving signal terminal RX- for data transmission. When one end of the optical transceiver module 230 (the end of the optical transceiver module 2〇3) is coupled to the device 250, the optical transceiver module 2〇3 includes an internally solidified resistor 211 and a resistor 213 coupled to the optical transceiver module. 2〇3 second transmission

Then immediately think that there is a host-side insertion 'so it will initiate a transmission-link training sequence. However, when the other end of the optical transceiver component 230 is not connected to the host 21, the link training sequence will fail to be established, and the device 250 will enter an abnormal working mode. In one embodiment, the abnormal mode of operation is a standard compatible mode in which the integrity of the signal sent by device 250 is tested. In one embodiment, the abnormal mode of operation is a test mode for testing the signal integrity of a link partner. In an embodiment, the second transmitting pair τ+/τ- of the optical transceiver module 203 also has an internally solidified resistor 211 and a resistor 213'. The resistor 211 and the resistor 213 are respectively coupled to the second transmitting pair τ+/τ_. One of them is connected to a ground. When the host 210 or the device 250 enters the standard compatible mode, data transfer between the host 210 and the device 250 is impossible. Therefore, for a link partner, it is currently not possible to accurately detect whether another link partner via the optical transceiver component is connected, so that the link partners (for example, the host and the device) can be stabilized by the optical transceiver component. The material is transmitted to establish optical fiber communication. Therefore, a new data transmission system and method is needed to solve this problem. The main feature of the present invention is that when the host or the device is coupled through the optical transceiver component, if the host or the device enters the abnormal working mode, the host or the device may jump out of the abnormal state through a control unit in the host or the device. The working mode is such that when the host and the device are both connected to the optical transceiver component and the host and the device are ready, normal data transmission is performed between the host and the device. In an embodiment, a host or a control unit in the device causes the host or device to jump out of the abnormal working mode and return to the host or set a detection link of the VIC10-001 lI00-TW/0608-A42664TWf 9 201203888 The status or a polling response signal status is used to monitor whether the device is connected to another device or host or another device or host with a response signal. The above host and device may be a host and device of a serial transmission interface specification, such as a Fast Peripheral Component Interconnect Standard (PCIE) interface specification or a Universal Serial Bus Release 3. 〇 (USB3.〇) interface specification, which passes The optical transceiver component performs optical fiber communication. Figure 3 is a flow diagram of data transfer by a first link partner and a second link partner (e.g., between a host and a device) in an embodiment of the present invention. In Figure 3, the first link partner (e.g., a host) polls whether a second link partner (e.g., a device) is inserted as a specific embodiment, and the second link partner (e.g., device) polls whether or not The case where a link partner (for example, a host) is coupled is the same as this embodiment, and details are not described herein again. In step 301, the first link partner is in a detection link state (Rx.detectstate). When the first link partner is coupled to one end of the optical transceiver component 23, the optical transceivers at both ends of the optical transceiver component 230 are transmitted and received. The modules all contain internally cured resistors, so the first link partner will detect the presence of differential termination impedance. When the first link partner detects the presence of the differential termination impedance, the first link partner initiates a link training sequence, at which point the first link partner enters a polling response signal state. The process proceeds to step 3. At step 303, the first link partner poll (p〇1Hng) receives a response signal from the second link partner within a first-predetermined time period, at which time the first-link partner is in-polling response (4) (4) The 'first-link partner' polls in the first-predetermined time to receive a low-frequency period from a second link partner, and the first-link partner is in the first predetermined time mentioned above. One in % from Qiu, Tianlun 珣 low frequency cycle signal energy VIC10-001 lI00-TW/0608-A42664TWf ° 201203888 (Polling.LFPS state). If so, the flow proceeds to step 3〇5. Then, the flow proceeds to step 307. In this embodiment, the first link partner spoon includes a first timer, and the first timer is initialized when the first key partner is in the polling response signal, and is used to count whether the timer is exceeded.
