Abstract
An optical fiber transmission system comprises a light emission source, a light receiving terminal and an optical fiber connected with the light emission source and the light receiving terminal. The light receiving terminal is connected with the optical fiber through a control module, and the control module comprises a controller, a signal analyzer and at least one reflection element, wherein the signal analyzer and the reflection element are respectively connected with the controller, a receiving address is preset in the signal analyzer, and the signal analyzer receives light signals transmitted by the optical fiber and analyzes the address information so as to judge whether the address information accords with the receiving address preset in the signal analyzer and sends a starting signal to the controller according to the judgment result. The controller controls movement of the reflection element according to the starting signal so as to lead the light signals to be reflected into the optical fiber through the reflection element to form standing waves. The optical fiber transmission system has the advantages of having small transmission loss and being capable of being connected with many light receiving terminals.
Description
Technical field
The present invention relates to a kind of fiber optic transmission system, relate in particular to a kind of concatenation type fiber optic transmission system.
Background technology
Fiber optic transmission system comprises photo-emission source, light-receiving terminal and the optical fiber that connects photo-emission source and light-receiving terminal.The connected mode of fiber optic transmission system mainly is divided into concatenation type and emanant two kinds.The concatenation type fiber optic transmission system refers to main fiber is connected with photo-emission source, and then a plurality of light-receiving terminals are connected with main fiber by branch optical fiber and optical connector respectively.The problem that this kind concatenation type fiber optic transmission system exists is, due to the loss in the optical signal transmission process and insertion loss, causes light signal decay to occur after propagating certain distance, thereby can only be with the minority light-receiving terminal of lightray propagation to front end.Emanant fiber optic transmission system refers to a plurality of light-receiving terminals are connected with photo-emission source by many optical fiber respectively, the signal that the light signal that the photo-emission source of the emanant fiber optic transmission system of this kind sends can only be broken down into some is transferred to respectively a plurality of light-receiving terminals, so its same existence can only connect the defective of less light-receiving terminal.
Summary of the invention
In view of above content, be necessary to provide a kind of loss less and can connect the fiber optic transmission system of more light-receiving terminal.
a kind of fiber optic transmission system, it comprises photo-emission source, light-receiving terminal and the optical fiber that connects photo-emission source and light-receiving terminal, the light-receiving terminal is connected with optical fiber by control module, control module comprises controller, signal analyzer and at least one reflecting element, signal analyzer and reflecting element are connected with controller respectively, be preset with receiver address in signal analyzer, it receives the light signal of Optical Fiber Transmission and analyzes its address information, to judge that whether its address information is consistent with default receiver address in signal analyzer, and send enabling signal according to judged result to controller, controller is controlled the motion of this reflecting element according to this enabling signal, so that being reflected in the element reflects back into optical fibers, light signal forms standing wave.
Above-mentioned fiber optic transmission system is provided with control module, the signal analyzer of this control module can judge that whether the address information of the light signal of Optical Fiber Transmission is consistent with default receiver address in signal analyzer, thereby the light signal that does not conform to is reflected in the element reflects back into optical fibers forms standing wave, can produce power not lose, therefore, fiber optic transmission system only can be at the branch road generation optical loss of light signal by control module, so photo-emission source can connect more light-receiving terminal.

Following embodiment further illustrates 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, the fiber optic transmission system 30 of the embodiment of the present invention comprises photo-emission source 31, light-receiving terminal 32, connect the optical fiber 33 of photo-emission source 31 and light-receiving terminal 32, be positioned at the optical fiber connector 34 of tie point of optical fiber 33 and the control module 35 that is positioned at light-receiving terminal 32 and the connecting portion of optical fiber 33.In the present embodiment, this photo-emission source 31 is light-emitting diode, and light-receiving terminal 32 is the computer terminal.
See also Fig. 2 and Fig. 3, control module 35 comprises controller 351, signal analyzer 352 and reflecting element 353, and this signal analyzer 352 and reflecting element 353 are connected with this controller 351 respectively.Be preset with receiver address in signal analyzer 352.
During use, the light signal that photo-emission source 31 sends transfers to a plurality of branch optical fibers 332 by main fiber 331 and the optical fiber connector 34, includes address information in this light signal.Light signal on branch optical fiber 332 imports in control module 35, and signal analyzer 352 is accepted light signal, analyzes the address information in light signal, to compare with the interior default receiver address of signal analyzer 352.As shown in Figure 2, when the address information in light signal was consistent with the receiver address of presetting, light signal entered light-receiving terminal 32 by control module 35 smoothly; As shown in Figure 3, when the address information in light signal does not meet mutually with the receiver address of presetting, signal analyzer 352 sends enabling signal to controller 351, controller 351 is controlled reflecting element 353 90-degree rotations according to this enabling signal, at this moment, light signal will be reflected element 353 and be reflected back branch optical fiber 332, and form standing wave on this branch optical fiber 332.
due to when the interior default receiver address of the address information in light signal and signal analyzer 352 does not meet mutually, can reflect to form standing wave by reflecting element 353 on branch optical fiber 332, therefore light signal can produce power not lose on this branch optical fiber 332, be that light signal only can produce power lose on the part branch road that the interior default receiver address of address information and signal analyzer 352 is consistent, and can all can the produce power loss on every optical fiber branch road as existing concatenation type fiber optic transmission system, thereby make photo-emission source 31 can connect more light-receiving terminal 32.
Be appreciated that, also can further preset format information in signal analyzer 352, when the form of the light signal that imports into when branch optical fiber 332 does not meet default format information, controller 351 is controlled reflecting element 353 rotations according to the enabling signal of signal analyzer 352 equally, forms standing wave light signal is reflected back branch optical fiber 332.
Be appreciated that control module 35 also can comprise two or more reflecting elements, and these reflecting elements are connected with controller all, are used for light signal is reflected back branch optical fiber 332 or lead-in light receiving terminal 32.
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.
