Embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated:
The reconfigurable optical fiber telecommunications system structure of intelligence of the present invention as shown in Figure 3, comprise a master station (also can dispose standby master station as required) and a plurality of remote terminals that are connected by optical cable each other, remote terminal has disposed the reconfigurable Optical Distribution Frame of intelligence of the present invention, and master station (can adopt the Ethernet mode as required by the far-end network management path, optical transceiver+special optic fibre mode, optical transceiver+non-special optic fibre+wavelength division multiplexer+wavelength dedicated mode, be with outer RS232 mode etc.) be connected with the communication module of the reconfigurable Optical Distribution Frame of each remote terminal intelligence and the reconfigurable Optical Distribution Frame of intelligence is monitored.Master station disposes NM server, can show each remote terminal ODF configuring condition in real time.In the time of need carrying out the ODF action, send operational order by the central station webmaster, the automatic complete operation of remote terminal ODF.
The reconfigurable Optical Distribution Frame structure of described intelligence comprises power module, array of photoswitch, main control module, local operation interface, communication module as shown in Figure 1.Wherein, array of photoswitch is the foundation that realizes reconfigurable ODF, forms and connect optical cable by several optical switches.Array of photoswitch can trigger the optical switch of appointment under master control module controls, finish between the optical fiber of appointment connection or by operation.Power module is responsible for that other parts provide required energy resource supply in the system.Communication module is used to realize between each remote terminal, communicating by letter between remote terminal and the central station.The realization of communication module can be adopted dedicated signaling optical fiber mode, also can adopt fine interior Coarse Wavelength Division Multiplexing technology (CWDM) to realize.The local operation interface provides standby system operation, can realize jumping fiber operation fast (need not manual plug flexible jumper) in remote terminal this locality.
Optical switch is a kind of optical device, can carry out break-make and switching to light signal in optical communication system.Core among the present invention is array of photoswitch, forms (the turnover optical fiber sum that concrete quantity can control is as required expanded flexibly) by a plurality of 1 * 1 optical switch.Each optical switch connects a pair of input and output optical fiber, and by its state of master control module controls.When needs at specific input and output optical fiber to change connecting or during cut-off state, send instruction by main control module by the corresponding optical switch of internal bus in array of photoswitch, indicate this optical switch to connect or blocking-up, thereby realized the change of connected relation between optical fiber in the Optical Distribution Frame system.Be the annexation and the operation principle thereof of example Mingguang City switch arrays and input, output optical fibre below with Fig. 2.The input optical cable has four optical fiber among the figure, respectively with A, B, C, D sign; The output optical cable also has four optical fiber, respectively with I, II, III, IV sign.4 optical switches are arranged in the array of photoswitch, connect A-I, B-II, C-III and D-IV respectively.Safeguarding one 4 * 4 array of photoswitch addressing view in the main control module, each optical switch has connection and ends two states, the control level control that its operating state is sent by main control module.When being communicated with between needs A-I, main control module sends operational order, and the optical switch between the A-I switches to on-state, can realize the straight-through of light signal between the A-I.End as light signal between needs B-II, then send operational order by main control module, the optical switch between the B-II switches to cut-off state, can realize ending of light signal between the B-II.So, can realize that the connection status between different fiber changes, also promptly control the connection or the cut-off state of light signal.When remote terminal has more optical fiber to control, can expand array of photoswitch scale and corresponding main control module addressing view, can realize flexible expansion.
