Embodiment Construction

[0049] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0050] In order to be backward compatible with USB2.0, USB3.0 / 3.1 adopts 9-pin design. Among them, 4 pins have exactly the same shape definition as USB2.0, while the other 5 pins are specially prepared for USB3.0. USB3.0 / 3.1 introduces full-duplex data transmission, two of the five lines are used to send data, two are used to receive data, and one is ground, which means that USB3.0 / 3.1 can synchronize at full speed Read and write operations, while the previous USB versions, namely USB2.0 and USB1.1 did not suppor...

Abstract

A hybrid optoelectronic transceiver used for a USB 3.0 interface and an optical cable of the hybrid optoelectronic transceiver. The hybrid optoelectronic transceiver includes a USB3.0 / 3.1 electrical transceiver, a USB2.0 electrical transceiver and a USB data mixer, wherein the USB3.0 / 3.1 electrical transceiver completes forwarding of USB3.0 signals, the USB2.0 electrical transceiver completes forwarding of USB2.0 signals, and the USB data mixer, on the one hand, mixes the two kinds of USB signals, and on the other hand, performs de-mixing on received mixed USB data, and respectively transmits the two kinds of USB data to the two kinds of electrical transceivers. According to the hybrid optoelectronic transceiver of the invention, the USB3.0 and USB2.0 signals can be transmitted in the same data packet, and therefore, the number of used optical fibers can be decreased, and operation is convenient, and the use of the USB3.0 standard interface is simpler, and the USB3.0 standard interface can be authentically compatible with a USB2.0 format in use.

Description

technical field [0001] The invention relates to the field of photoelectric data transmission, in particular to a novel active hybrid photoelectric transceiver and an optical cable for a USB3.0 / 3.1 interface. Background technique [0002] USB3.0 is also known as SuperSpeedUSB, which provides a standard interface for various devices connected to PC or audio / high frequency equipment. As a new generation of USB interface, USB3.0 / 3.1 is characterized by a very fast transmission rate, which can theoretically reach 5Gbps / 10Gbps, which is 10 times faster than the current 480Mbps HighSpeedUSB (referred to as USB2.0). The appearance of USB3.0 / 3.1 is basically the same as the current USB interface, and can be compatible with USB2.0 and USB1.1 devices. [0003] Compared with the current USB2.0 interface, USB3.0 / 3.1 adds more physical buses in parallel mode. On the basis of the original 4-wire structure (power, ground, and 1 pair of data), USB3.0 / 3.1 adds 4 (two pairs) lines for receiv...
