Description
Technical field
The present invention relates to a kind of joints of optical fibre.
Background technology
Because the consumer increases the transmission demand of quantity of information day by day, so wieldy transmission interface USB specification and speed are also risen to the USB3.0 of present development by USB1.0, or even the specification of the USB4.0 that will soon advocate.
Transfer rate also rises to present 4.8Gb/s (USB3.0) by original 1.5Mb/s, or even 10Gb/s (USB4.0).USB3.0 is under the speed of high-transmission like this, and the electric capacity galvanomagnetic effect of Electromagnetic Interference and transmission line causes the speed of information transmission and distance to be inversely proportional to, and how to average out a little and to satisfy the demands of consumers at this, will be all suppliers' important topic.
The mode of USB3.0 use at present; Identical with the mode of traditional USB1.0 all is to adopt electronic signal to transmit; Discrepancy makes the speed of transmission reach 4.8Gb/s for having added one group of four-wire type full duplex differential signal transmission, but also because the electric transmission excessive velocities; The loss of signal that lead caused and decay make length of transmission line can't be higher than 3 meters, and the length that is lower than the USB demand need reach 5 meters specifications.
And the idea of present USB4.0; Also be to operate purely, so though the distance of transmission can be elongated manyly, the quantity of required optical element will increase many by light transmission; And because the shank of transmission needs optical alignment; So in the time of plug, the optical element of plastics suffers damage easily, causes the bad of optical registration in the course of time after the meeting.
Summary of the invention
In view of this, be necessary to provide a kind of information transmission that reaches long distance, and keep the joints of optical fibre of joint rigid demand.
A kind of joints of optical fibre; It comprises housing and metal joint; The end that said metal joint is positioned at said housing is used for linking to each other with electronic equipment; Be provided with optical fiber in the said housing; Have photodiode, light emitting diode and processing unit in the said metal joint, said photodiode is used for light signal with said Optical Fiber Transmission and converts electric signal into and export to said processing unit and handle being suitable for said metal joint transmission, and said light emitting diode is transferred at said metal joint to send the light signal of representing electric signal and be coupled to said optical fiber under the electric signal control of said processing unit and transmits.
Compared to prior art, the joints of optical fibre of the embodiment of the invention adopt optical signal transmission fiber and metal joint, and optical fiber transmission signal has long apart from characteristics and metal joint has kept the rigid demand of joints of optical fibre joints, is fit to repeatedly plug.
