The optical link damage compensation device based on fuzzy recognition comprises a transmitter, nodes and a receiver, wherein the transmitter is connected with the first node through an optical fiber, the nodes are connected in turn by the optical fiber, the last node is connected with the receiver by the optical fiber; the nodes are connected with a fuzzy recognition controller in parallel by a variable gain optical amplifier and then connected with a tunable dispersion compensator and a fixed gain optical amplifier in series. The physical damage compensation ability of the tunable dispersion compensator and the variable gain optical amplifier in the network is used, the dynamic transmission quality optimization self-adaptive transmission control from a transmitting end to a receiving end in the flexible transparent optical network field is realized, and by adopting the fuzzy recognition controller, the dynamic adjustment and improvement of the whole optical path transmission quality from a source end to a destination are realized, so as to solve the problems that the transmission quality of the optical signal is deteriorated due to physical damage during the transmission process of the optical signal.
Description
One, technical field
The utility model relates to optical link damage compensation arrangement, the optical link damage compensation arrangement that is based on fuzzy diagnosis that is specifically related to.
Two, background technology:
Development along with optical communication technique, increasing full light restructural switching node is able to a large amount of planning and uses in transmission network, transparent optical networks refers to that signal is to transmit from source node to destination node in pure smooth territory, namely reduce the quantity of electric reclaim equiment, saved again the network construction cost because light-the electrical-optical conversion causes.Various restructural switching equipment have been expanded the flexible nature of optical transfer network simultaneously; make photosphere have behavioral characteristics, can according to required configured bandwidth, dynamically set up the wavelength route; and trellis wavelength protection and the Restoration Mechanism of various network are provided, strengthened the survivability of optical-fiber network.
The transparency of optical-fiber network and flexibility have brought some new problems, and various physical layer damages will be accumulated along optical link, and due to reasons such as heavy-routes after variations in temperature, optical fiber vibration and fault, physical damnification can occur dynamically to change.In lacking light territory 3R regeneration function, the physical damnification of light signal in transmission can produce accumulation due to flexible transparent optical networks, and impacts of these damage accumulation might cause that the transmission quality of signal is deteriorated even not to be satisfied system transmissions and require problem.
Three, summary of the invention:
The purpose of this utility model is to provide the optical link damage compensation arrangement based on fuzzy diagnosis, and this optical link damage compensation arrangement based on fuzzy diagnosis is used for solving light signal and causes the deteriorated problem of transmission quality of signal at the physical damnification of transmission.
The technical scheme that its technical problem that solves the utility model adopts is: this optical link damage compensation arrangement based on fuzzy diagnosis is made of reflector, node, receiver, reflector connects first node by optical fiber, connect by optical fiber successively between node, last node is connected by optical fiber with receiver; Node by variable gain optical amplifiers with after the fuzzy diagnosis controller is in parallel, then the formation of connecting with Tunable Dispersion Compensator, fixed gain image intensifer.
Beneficial effect:
The utility model utilizes the physical damnification compensation ability of Tunable Dispersion Compensator in network, variable-gain image intensifer, realization is at the adaptive transmitted control of flexible transparent optical networks field from transmitting terminal to receiving terminal dynamic transmission quality optimization, and by the fuzzy diagnosis controller, and then realize adjusting and the improvement of the whole optic path quality from the source to the destination dynamically.
Four, description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of node in the utility model.
1 reflector, 2 nodes, 3 receivers, 4 optical fiber, 5 variable gain optical amplifiers, 6 fuzzy diagnosis controller 7 Tunable Dispersion Compensator 8 fixed gain image intensifers.
Five, embodiment:
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, this optical link damage compensation arrangement based on fuzzy diagnosis is made of reflector 1, node 2, receiver 3, node 2 has a plurality of, reflector 1 connects first node 2 by optical fiber 4, be connected by optical fiber 4 successively between first node 2 and other node, last node is connected by optical fiber 4 with receiver 3.
Consult Fig. 2, node 2 by variable gain optical amplifiers 5 with after fuzzy diagnosis controller 6 is in parallel, then the formation of connecting with Tunable Dispersion Compensator 7, fixed gain image intensifer 8.
the problem that faces for the optical signal transmission quality optimization, the utility model based on tunable light device (as Tunable Dispersion Compensator, the variable-gain image intensifer) and the parameters self-tuning of transmitting state information perception compensation control, for parameters such as Optical Signal To Noise Ratio (OSNR), the light signal physical damnification is control effectively, thereby completed, each adjustable physical damnification compensating device in optical link is carried out dynamically end to end performance adjusting, be sent to the device regulated of each Nodes (as Tunable Dispersion Compensator by the signalling module of control plane, the variable-gain image intensifer), the device regulated of each node is (as Tunable Dispersion Compensator, the variable-gain image intensifer) complete the adjusting of tunable light device according to the regulated quantity of fuzzy controller output, thereby realize the optimization to transmission quality, solved the transmission quality deteriorated problem that the physical damnification of light signal in transmission causes signal.
