Following embodiment further specifies the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Below in conjunction with drawings and Examples fiber optic transmission system of the present invention is described in further detail.
See also Fig. 1, a kind of fiber optic transmission system 100 of the embodiment of the invention, it comprises a photo-emission source 10, a plurality of light- receiving terminal 20,30, one the first optical fiber 40 of a plurality of optical fiber connector, a plurality of the second optical fiber 50 and a plurality of the 3rd optical fiber 60.In the present embodiment take 3 optical fiber connector 30 namely first optical fiber connector 31, second optical fiber connector 32, the 3rd optical fiber connector 33 the present invention is described as example, in other embodiments, the number of the optical fiber connector 30 is not limited to 3 of present embodiment.Wherein, photo-emission source 10 is laser diode in the present embodiment, and in other embodiments, photo-emission source also can be the photo-emission source that transmits.This light-receiving terminal 20 can be the terminal of same type, as is DVD player, terminal or sound-box device etc., also can be dissimilar terminals, is DVD player such as certain, and certain is terminal and/or certain for sound-box device etc.
This first optical fiber 40 connects these photo-emission source 10 to first optical fiber connector 31, and each second optical fiber 50 connects two adjacent optical fiber connector, each the 3rd optical fiber 60 connect these optical fiber connector to the corresponding light-receiving terminal 20 of these optical fiber connector.
These a plurality of optical fiber connector 30 are provided with the first slot 301, the second slot 302 and the 3rd slot 303, and wherein, the first slot 301 of these first optical fiber connector 31 is connected with this photo-emission source 10 by this first optical fiber 40.The second slot 302 of these a plurality of optical fiber connector 30 is connected with the first slot 301 of second optical fiber connector 32 by the second optical fiber 50, the second slot 302 of these second optical fiber connector 32 is connected with the first slot 301 of the 3rd optical fiber connector 33 by the second optical fiber 50, so analogizes.The 3rd slot 303 of these each optical fiber connector 30 is connected with corresponding light-receiving terminal 20 by the 3rd optical fiber 60.This light-receiving terminal 20 comprises a photoelectric conversion unit 22, and this photoelectric conversion unit 22 is used for and will be converted to the signal of telecommunication from the light signal of the 3rd optical fiber 60 transmission.
This fiber optic transmission system 100 also comprises a plurality of control modules 70, each light-receiving terminal 20 corresponding control module 70, and this light-receiving terminal 20 links to each other with the 3rd optical fiber 60 by control module 70.Wherein, this control module 70 comprises controller, signal analyzer and reflecting element (not shown).This signal analyzer and reflecting element link to each other with this controller respectively.Be preset with receiver address in the signal analyzer.
When fiber optic transmission system 100 work, the light signal that photo-emission source 10 sends transfers to a plurality of the 3rd optical fiber 60 by this first optical fiber 40, a plurality of optical fiber connector 30 and a plurality of the second optical fiber 50, finally transfers to light-receiving terminal 20 by control module 70.Include address information in this light signal.Light signal on the 3rd optical fiber 60 imports in the control module 70, and the signal analyzer receiving optical signals in the control module 70 is analyzed the address information in the light signal, with signal analyzer in default receiver address compare.When the address information in the light signal was consistent with the receiver address of presetting, light signal entered light-receiving terminal 20 by control module 70 smoothly; The photoelectric conversion unit of light-receiving terminal 20 inside converts light signal to the signal of telecommunication for light-receiving terminal 20.When the address information in the light signal and default receiver address were inconsistent, signal analyzer sent enabling signal to controller, starts reflecting element light signal is reflected back the 3rd optical fiber 60.
Because when receiver address default in the address information in the light signal and the signal analyzer does not meet, can reflect to form standing wave by reflecting element on the 3rd optical fiber 60, therefore light signal can produce power not lose on this branch optical fiber 60, thereby makes photo-emission source 10 can connect more light-receiving terminal 20.
Also can further preset format information in the signal analyzer, when the light signal form that imports into when the 3rd optical fiber 60 does not meet default format information, controller according to the enabling signal control reflecting element work of signal analyzer, forms standing wave light signal is reflected back the 3rd optical fiber 60 equally.
Above-mentioned fiber optic transmission system can separately and respectively be delivered to corresponding light-receiving terminal by optical fiber transmission with the light signal of photo-emission source emission by the optical fiber connector, embodies high frequency range and the remote characteristic that transmits of optical fiber.
In addition, those skilled in the art also can do other variation in spirit of the present invention, and certainly, the variation that these are done according to spirit of the present invention all should be included in the present invention's scope required for protection.
