Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.
Optical fiber transmission is becoming popular as a new signal transmission technology, and optical signals are transmitted in optical fibers, and the signal transmission rate is undoubtedly, and optical signals are converted into optical signals and transmitted out, and the optical signals are restored into electrical signals at a receiving end, so that an optical-electrical transmission scheme is provided. In high-speed signal transmission, optical fibers can be transmitted at a long distance, which cannot be realized by electric wires. The USB3.0A interface provided in this embodiment is converted to Micro B, so as to use this signal transmission scheme for communication.
The main embodiment is as follows:

Because The A interface does not have an identification pin ID, and The identification pin ID of The Micro B interface is suspended, The device does not have The OTG (On-The-Go, namely, under The condition of no Host, The data transmission between The devices is realized) function specified by The USB3.0 standard. In the using process, the first photoelectric conversion module on the A interface performs electro-optical conversion on data sent by the host, the converted optical signal is transmitted to the second photoelectric conversion module of the Micro B interface through the optical fiber, and the second photoelectric conversion module restores the received optical signal into an electric signal through photoelectric conversion and outputs the electric signal to the slave. Since data transmission is bidirectional transmission, when the slave transmits data back to the host, similarly, the second photoelectric conversion module of the Micro B interface performs photoelectric conversion on the data and outputs the data, and after the data is transmitted by the optical fiber, the first photoelectric conversion module on the a interface receives the optical signal and restores the optical signal to an electric signal, and outputs the electric signal to the host. The optical communication is used for signal transmission, so that signal distortion is smaller, and the communication cable can be made longer under the same communication quality requirement.
The USB3.0 standard provides for independent high-speed signal transmission channel and high-speed signal reception channel, and because the signal transmission and signal reception use mutually independent channels, the communication efficiency is greatly improved compared to USB 2.0.
In this embodiment, the interface a includes a first high-speed differential signal transmitting terminal and a second high-speed differential signal receiving terminal, where the first high-speed differential signal transmitting terminal is connected to an SSTX +/-pin of the interface a, and the second high-speed differential signal receiving terminal is connected to an SSRX +/-pin of the interface a; the Micro B interface comprises a first high-speed differential signal receiving end and a second high-speed differential signal sending end, the first high-speed differential signal receiving end is connected with an SSRX +/-pin of the Micro B interface, and the second high-speed differential signal sending end is connected with an SSTX +/-pin of the Micro B interface; the first high-speed differential signal transmitting end and the first high-speed differential signal receiving end are connected through an optical fiber, and the second high-speed differential signal transmitting end and the second high-speed differential signal receiving end are connected through an optical fiber.

As shown in fig. 1 to 3, each of the first high-speed differential signal receiving terminal and the second high-speed differential signal receiving terminal includes a first photodetector and a first amplifier, a detection end of the first photodetector is optically coupled to an optical fiber, an output end of the first photodetector is connected to an input end of the first amplifier, and an output end of the first amplifier is correspondingly connected to an SSRX +/-pin of the a interface or an SSRX +/-pin of the Micro B interface.
The first embodiment is as follows:
on the basis of the above main embodiment, as shown in fig. 1, if the device does not consider the USB2.0 compatible function (i.e., the D +/-pins of the a interface and the Micro B interface are suspended), only a high-speed signal transmission channel is provided, and an external power interface is provided at the Micro B interface, and an external power supply provides a working power supply for the second photoelectric conversion module, the communication cable may adopt an all-optical cable, so that the length of the communication cable can be greatly extended, for example, 50-100 m can be achieved. The specific length of the communication cable is influenced by the fiber specification.
Example two:
on the basis of the main embodiment, on the premise that the USB2.0 protocol is compatible, the present embodiment further provides a low-speed signal transceiving channel.
As shown in the main embodiment, the high-speed signal transmission channel uses an optical fiber for communication, and in order to be compatible with the USB2.0 protocol, the apparatus is further provided with a low-speed signal transceiving channel.
Specifically, as shown in fig. 2, a low-speed signal transceiving channel and a power transmission channel are further disposed on the interface a and the interface Micro B, the low-speed signal transceiving channel and the power transmission channel are multiple mutually insulated wires, low-speed signal transceiving occupies a data transceiving pin D +/-of the interface a and the interface Micro B, and the data transceiving pin D +/-performs bidirectional transmission of a group of differential signals. The two ends of a wire of the low-speed signal transceiving channel are respectively and correspondingly connected with a data transceiving pin D +/-of the interface A and the data transceiving pin D +/-of the interface Micro B, the two ends of a power bus VBUS of the power supply transmission channel are respectively connected with a power pin VBUS of the interface A and the power pin VBUS of the interface Micro B, the two ends of a grounding wire are respectively connected with a grounding pin GND of the interface A and the grounding pin GND of the interface Micro B, and the wires and the optical fibers are integrated on a communication cable. Considering the influence of the length of the wire on low-speed signal transmission, the larger the length of the wire is, the poorer the anti-interference capability of the low-speed signal is, so that the length of the communication cable in the scheme can be generally 5-7 m, and the communication cable is superior to the traditional pure cable communication.
Example three:

However, if the scheme of the second embodiment adopts an electro-optical combination method for communication, the communication quality is still affected by the length of the cable, because the low-speed signal transceiving channel performs bidirectional transmission of the differential signal. Therefore, a scheme that optical fiber communication is adopted for both high-speed signal transmission and low-speed signal transmission is proposed.
Specifically, as shown in fig. 3, the first photoelectric conversion module of the interface a and the second photoelectric conversion module of the Micro B interface are both provided with a low-speed signal transceiver, the low-speed signal transceiver occupies data transceiver pins D +/-of the interface a and the Micro B interface, and the data transceiver pins D +/-transmit differential signals in two directions.

The signal controller judges the current signal flow direction according to the signal of the data receiving and transmitting pin D +/-and controls the second driver to drive the second laser to emit light if the current signal flow direction is judged to be in a data transmitting state, and the electric signal is converted into an optical signal and output through an optical fiber; and if the current state is the data receiving state, the second photoelectric detector restores the detected optical signal into an electric signal, and the electric signal is amplified by the second amplifier and then is output through the data receiving and transmitting pin D +/-D.
