Problems solved by technology
[0004] The current method used by USB3.0 is the same as the traditional USB1.0 method, which uses electronic signals for transmission. The difference is that a set of four-wire full-duplex differential signal transmission is added, so that the transmission rate reaches 4.8Gb / s, but also because the electronic transmission speed is too fast, the signal loss and attenuation caused by the wire make the transmission line length cannot be higher than 3 meters, and the longest specification that is lower than the USB requirement needs to reach 5 meters
[0005] The current idea of USB4.0 is also purely operated by optical transmission, so although the transmission distance can be lengthened a lot, the number of optical components required will increase a lot, and because the transmission joint part requires optical alignment, Therefore, when plugging and unplugging, the plastic optical components are easily damaged, which will cause poor optical alignment over time

Embodiment Construction
[0024] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0025] see figure 1 The optical fiber connector 10 provided by the first embodiment of the present invention has a housing 11 and a metal joint 15, an optical fiber 12 is arranged in the housing 11, and a photodiode (PD, photo diode) 13a, a light emitting diode ( LD, light diode) 13b, carrier 14 and processing unit 16.
[0026] Both ends of the housing 11 have a metal joint 15, that is, the optical fiber connector 10 has two metal joints 15, and the metal joints 15 are connected through the optical fiber 12. This embodiment uses a metal joint 15 as an example to introduce the optical fiber connector 10. structure.
[0027] The casing 11 is generally made of plastic material for covering the optical fiber 12, such as polyethylene, polypropylene, polystyrene, polyvinyl chloride or polyethylene terephthalate.
[0028] The metal connector 15...

An optical fiber connector comprises an optical fiber and a metal connector. The metal connector is located at one end of a shell and used for connection with an electronic equipment; the optical fiber is disposed in the shell; a photodiode, a light emitting diode and a processing unit are provided in the metal connector; the photodiode is used for converting optical signal transmitted in the optical fiber into electrical signal, outputting to the processing unit for processing, to adapt to transmission by the metal connector; under control of the electrical signal transmitted from the metal connector to the processing unit, the light emitting diode emits optical signal representing the electrical signal, and couples to the optical fiber for transmission.
Description
technical field [0001] The invention relates to an optical fiber connector. Background technique [0002] Due to the increasing demand of consumers for the transmission of information, the USB specification and speed of the easy-to-use transmission interface have also been upgraded from USB1.0 to the current USB3.0, and even the soon-to-be-advocated USB4.0 specification. [0003] The transmission rate has also been increased from the original 1.5Mb / s to the current 4.8Gb / s (USB3.0), or even 10Gb / s (USB4.0). At such a high transmission speed of USB3.0, the electromagnetic wave interference and the capacitive electromagnetic effect of the transmission line cause the speed of information transmission to be inversely proportional to the distance. How to achieve a balance here and meet the needs of consumers will be a key issue for all suppliers. important topic. [0004] The current method used by USB3.0 is the same as the traditional USB1.0 method, which uses electronic signa...
