Description
Technical field
The present invention relates to a kind of fibre-optic transmission system (FOTS), more particularly to a kind of concatenation type fibre-optic transmission system (FOTS).
Background technology
Fibre-optic transmission system (FOTS) includes photo-emission source, optical receiver terminal and the light of connection photo-emission source and optical receiver terminal
It is fine.The connected mode of fibre-optic transmission system (FOTS) is broadly divided into concatenation type and emanant two kinds.Concatenation type fibre-optic transmission system (FOTS) refer to by
Main fiber is connected with photo-emission source, and then multiple optical receiver terminals are connected by branch optical fiber and optical connector with main fiber respectively
Connect.The problem of this kind of concatenation type fibre-optic transmission system (FOTS) is present is, due to the transmission loss during optical signal transmission and insertion damage
Consumption, causes optical signal to be decayed after certain distance is propagated, so that can only be by a small number of light-receivings of lightray propagation to front end
Terminal.Emanant fibre-optic transmission system (FOTS) refers to multiple optical receiver terminals respectively by a plurality of optical fiber with photo-emission source being connected, should
The optical signal that the photo-emission source of the emanant fibre-optic transmission system (FOTS) of kind is sent can only be broken down into a number of signal and transmit respectively
To multiple optical receiver terminals, therefore it is equally existed the defects of can only connecting less optical receiver terminal.
The content of the invention
In view of the foregoing, it is necessary to provide a kind of transmission loss it is smaller and can connect more optical receiver terminal optical fiber pass
Defeated system.
A kind of fibre-optic transmission system (FOTS), it includes photo-emission source, optical receiver terminal and connection photo-emission source and light-receiving is whole
The optical fiber at end, optical receiver terminal are connected by control module with optical fiber, and control module includes controller, signal analyzer and at least
One reflecting element, signal analyzer and reflecting element are connected with controller respectively, are preset with signal analyzer and receive address,
Whether the optical signal of its reception optical fiber transmission simultaneously analyzes its address information, to judge its address information with being preset in signal analyzer
Reception address be consistent, and enabling signal is sent to controller according to judged result, controller controls according to the enabling signal
The motion of the reflecting element, so that optical signal is reflected back in optical fiber by reflecting element forms standing wave.
Above-mentioned fibre-optic transmission system (FOTS) is provided with control module, and the signal analyzer of the control module can determine whether optical fiber transmission
Whether the address information of optical signal is consistent with default reception address in signal analyzer, so that the optical signal quilt not being consistent
Reflecting element, which is reflected back in optical fiber, forms standing wave, will not produce energy loss, and therefore, fibre-optic transmission system (FOTS) can only lead in optical signal
The branch road for crossing control module produces optical loss, so photo-emission source can connect more optical receiver terminal.

Embodiment
Below in conjunction with the accompanying drawings and embodiment is described in further detail to the fibre-optic transmission system (FOTS) of the present invention.
Referring to Fig. 1, the fibre-optic transmission system (FOTS) 30 of the embodiment of the present invention includes photo-emission source 31, optical receiver terminal 32, connected
Connect photo-emission source 31 and optical receiver terminal 32 optical fiber 33, positioned at optical fiber 33 tie point the joints of optical fibre 34 and positioned at light
Receiving terminal 32 and the control module 35 of the connecting portion of optical fiber 33.In the present embodiment, the photo-emission source 31 is light emitting diode,
Optical receiver terminal 32 is computer terminal.
Optical fiber 33 includes a main fiber 331 and a plurality of branch optical fiber 332 being respectively connected with main fiber 331, and each
Branch optical fiber 332 is connected by a joints of optical fibre 34 with main fiber 331.
Fig. 2 and Fig. 3 is referred to, control module 35 includes controller 351, signal analyzer 352 and reflecting element 353, should
Signal analyzer 352 and reflecting element 353 are connected with the controller 351 respectively.Reception ground is preset with signal analyzer 352
Location.
In use, the optical signal that photo-emission source 31 is sent is transmitted to multiple points by main fiber 331 and the joints of optical fibre 34
Branch optical fiber 332, include address information in the optical signal.Optical signal on branch optical fiber 332 is passed in control module 35, signal
Analyzer 352 receives optical signal, analyzes the address information in optical signal, with default reception address in signal analyzer 352
It is compared.As shown in Fig. 2 when the address information in optical signal is consistent with default reception address, optical signal smoothly leads to
Cross control module 35 and enter optical receiver terminal 32；As shown in figure 3, when the address information in optical signal and default reception address phase
When not meeting, signal analyzer 352 sends enabling signal to controller 351, and controller 351 controls according to the enabling signal to be reflected
Element 353 is rotated by 90 °, and now, optical signal will be reflected back branch optical fiber 332 by reflecting element 353, and in the branch optical fiber 332
Upper formation standing wave.
Due to when the address information in optical signal with signal analyzer 352 it is default reception address do not meet mutually when, point
Standing wave can be reflected to form on branch optical fiber 332 by reflecting element 353, therefore optical signal will not produce on this branch optical fiber 332
Raw energy loss, i.e. optical signal only can be in address informations and the default part for receiving address and being consistent in signal analyzer 352
Energy loss is produced on branch road, energy can be produced on every optical fiber branch road without such as existing concatenation type fibre-optic transmission system (FOTS)
Loss, so that photo-emission source 31 can connect more optical receiver terminals 32.
It is appreciated that in signal analyzer 352 can also further preset format information, when the light that branch optical fiber 332 is passed to
When the form of signal does not meet preset format information, controller 351 controls anti-also according to the enabling signal of signal analyzer 352
Penetrate element 353 to rotate, optical signal is reflected back into branch optical fiber 332 forms standing wave.
It is appreciated that control module 35 may also comprise two or more reflecting elements, and these reflecting elements are equal
It is connected with controller, for optical signal to be reflected back into branch optical fiber 332 or imports optical receiver terminal 32.
In addition, those skilled in the art can also do other changes in spirit of the invention, certainly, these are according to present invention essence
The change that god is done, it should all be included in scope of the present invention.
