Optical fiber connector

Abstract

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.

AI Technical Summary

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
