Description of the Invention: [Technical Field] The present invention relates to a universal serial bus (USB) connector, and more particularly to an optical to electrical/electrical to optical conversion module (photoelectric mode) Group) and associated high speed electrical connections are integrated into an internal USB connector. [Prior Art] USB refers to an external busbar standard that requires electrical connections and data transmission operations to allow electronic devices to interface and communicate with each other. The USB system is usually used to replace the RS232 serial interface and the parallel interface to connect peripheral devices (eg, mouse, keyboard, printer, etc.) to a computer (eg, desktop and laptop). . Most desktop and laptop computers on the market today are equipped with multiple USB connectors, each of which is designed to mate with a respective USB plug. A typical USB connector is equipped with electrical contacts that are designed to couple electrical contacts external to the USB connector for data transfer and power supply functions. Some of the electrical contacts of the usb connector are used to couple the electrical contacts of a USB plug to the circuitry of the USB connector, and some of the electrical contacts of the USB connector are used to couple the circuitry of the USB connector to form A conductive trace on a motherboard on a computer. Electrical traces on the motherboard route electrical signals between the circuitry of the USB connector and circuitry mounted on the motherboard, such as, for example, a USB controller connected to one of the main processors of the computer . In recent years, due to the increase in the amount of data traffic between computers and other peripheral devices, USB connectors have been equipped to support the increased speed: that is, from 1 million megabits per second supplied by USB 1 (MbpS) speed increased to 151480.doc 201140967 The 480 Mbps and 5 billion bit per second (Gbps) speeds provided by the USB2 standard and the USB3 standard. There continues to be a need for one of the computers to operate at even higher speeds to peripheral communications. For example, most high-resolution, instant video will require data rates greater than 10 Gbps. At speeds greater than 1 〇 ^ 1^5, conventional copper wire connections for U S B devices will become difficult to implement and will have limited success. Therefore, using one of the early versions of the USB connection is compatible with one of the optical connections becoming highly desirable. In any USB connection that is actually implemented in the battery, the USB controller 1C mounted on the motherboard of the computer manages the data communication. The controller 1 (: is electrically coupled to the main processor of the computer on one side via traces on the motherboard and electrically coupled to the adjustment signal on the other side to facilitate transmission of one of the physical layer devices. The entity then The layer device is connected to the USB connector via a trace on the motherboard. In the conventional USB connection, a copper wire based on one of the cables is inserted into the USB connector so that it can be between the computer and its peripheral devices To transmit an electrical signal, in order to introduce an optical connection to one of the USB connectors, an optical to optical and optical to electrical conversion module (optical module) is performed in place of the above physical layer device. The optical connection is implemented using two types of configurations. In one of the two types of configurations, the optoelectronic module is soldered to one of the electrical sockets on the motherboard or by directly soldering the photovoltaic module electrical contacts to the mother a contact pad on the board is mounted on the motherboard. The fiber-optic jumper is used to provide the optical module and the USB connector socket inserted in the motherboard mounted on the motherboard. An optical connection between the dry connectors. The external USB sensation is modified to include two fibers terminated in a light 151480.doc 201140967 connector inserted in the U s B plug that terminates the ϋ s B cable The fiber optic jumper has one of the first connectors on one of the first ends (the first connector mates with the USB connector) and one of the second ends of the first connector a second connector (the second connector is in close cooperation with an optical connector for the photovoltaic module). The jumper cable typically includes a transmission fiber and a receiving fiber for each USB connector. The optoelectronic module usually includes a laser diode for each optical connector to transmit an optical signal and a photodiode to receive an optical signal. However, if it is desired to support multiple USB connectors, a photovoltaic module may contain multiple a laser body and an equal number of photodiodes and connected to a jumper cable having a corresponding number of jumper fibers. The electrical contacts of the optoelectronic module are electrically coupled via conductive traces on the motherboard To install on the motherboard a controller device (ie, a USB controller IC). The controller device is electrically coupled to a main processor of the computer via a trace on the motherboard. The optoelectronic module includes a receiving device from the router. An electrical signal on the trace of the motherboard and converting the electrical signal into an electrical drive signal for driving the laser diode of the photovoltaic module. The corresponding optical signals generated by the laser diode are then An optical system of the optoelectronic module is optically coupled to an end of the transmission fiber fastened to the second connector of the jumper cable. Received in the optoelectronic module on the receiving fiber of the jumper When the optical signal is used, the optical optical system of the optical module of the optical fiber module is optically coupled to the optical diode of the photoelectric module. The optical diode generates a corresponding electrical signal. The photoelectric module is delivered to the controller device through a trace of the motherboard. The controller device then delivers the electrical signal to the main processor or another processor of the computer via the motherboard trace 151480.doc 201140967. In the other of the two types of configurations, the optoelectronic module equipped with an integrated passive optical connector is included in the USB connector. The passive optical connector directly opposes the optical signal to and from the passive optical connector located in the USB plug attached to the end of the external optical USB cable. Therefore, jumper fibers are not used in this configuration. One end of a flex circuit is connected to the optoelectronic module and the opposite end is connected to an electrical connector mounted on the computer motherboard. The electrical connector interfaces the flex circuit with the motherboard. An electrical signal is sent to the controller device through the trace of the motherboard to the controller device and is routed from the controller device to the interface between the flex circuit and the motherboard. The electrical signals are then delivered through the traces of the flex circuit to the optoelectronic module included in the USB connector. In the optoelectronic module, the electrical signals are used to drive the laser diode to produce an optical 彳 §. The optical signals generated by the laser diodes of the optoelectronic module are optically coupled via the optical system of the optoelectronic module and the integrated passive optical connector to be included in the modified optical USB cable The passive optical connector within the USB plug at the end of the shai transmission fiber. Receiving the optical signals at the opposite ends of the transmission fiber in the passive optical connector contained within the USB plug, the passive optical connector then coupling the optical signals to be included in the USB socket housing The passive optical connector of the optoelectronic module; the photodiode in the optoelectronic module at the opposite end receives the optical signals via the optical system, and the receiver circuit of the optoelectronic module generates a corresponding electrical signal. The electrical signal is then routed through the flex circuit traces 151480.doc 201140967 through the interface between the flex circuit and the motherboard to the trace of the motherboard. The electrical signals are then routed through the traces of the motherboard to the controller device and then the electrical signals are sent from the controller device to the host processor. The need for several interfaces for transmitting signals between the USB connector mounted on the motherboard and the controller device causes the major drawbacks of the two types of configurations of the optical connections described above. In configurations using fiber optic jumper cables, the reflection loss is also commonly referred to as Fresnel loss, and there is additional optical loss at each optical interface due to misalignment of the optical components. In order to reduce the cost of the total USB connector, the end of the transmission fiber and the end of the receiving fiber are generally split, but remain unpolished, which can result in optical signals being coupled to or from the end of the fibers. The unpredictable loss of the position of the coupled output optical signal. In some cases, an index matching epoxy is also used to attach the ends of the fibers to an optical component such as one of the lenses of the optical system. Bubbles can occur at the tip of the fiber in the epoxy, which can result in various interfaces where the optical signal encounters the gas/package portion (i.e., when the signal encounters the outer surface of the bubble) And again when the signal encounters the inner surface of the bubble. Therefore, the use of this fiber jumper cable creates many opportunities for optical loss, which can degrade signal quality. While other types of configurations of such optical connections are substantially eliminating external optical jumper cables, an additional electrical connection is required to interface the flex circuit with the motherboard. This extra electrical connection creates the possibility of signal loss and connection to the monthly t* force problem, which can degrade signal quality. In addition, the electrical connection has a cost associated with increasing the total cost associated with the USB connector. The process involving the buckling circuit typically also suffers from the use of a hard printed circuit 15148. <j〇c 201140967 board (PCB) The resulting throughput and variability are lower throughput and may be more variability. Therefore, there is a need for a USB connector that has optical capabilities for processing optical signals and that does not require the use of an optical jumper cable or a flex circuit, thereby eliminating the optical USB configuration. The above issues associated with the type.
