Embodiment three
The fiber full-switching equipment that present embodiment provides is not only divided the row of exchange hole with respect to embodiment one, and the row of exchange hole are also divided.As shown in Figure 4, the exchange hole 11 in the fiber full-switching equipment that present embodiment provides on the power board 1 still is uniform rectangular array, and a side of exchange hole 11 is used to insert cord circuit fiber optic links device, and opposite side is used to insert the circuit optical fiber linker.Preferably, with the corresponding delegation of every outside line optical fiber exchange hole, the every corresponding row exchange hole of cord circuit optical fiber, the circuit optical fiber linker of fixing every outside line optical fiber one end can only be limited on the row of this outside line optical fiber correspondence and move, and can only insert in the exchange hole in this row, and that a pair of cord circuit fiber optic links device of fixing cord circuit optical fiber two ends can only be limited in listing of this cord circuit optical fiber correspondence is mobile, and can only insert in the exchange hole of these row.
Exchange hole 11 is an example with the rectangular array that is arranged in 8x4 in Fig. 3, has on the power board of 8 row exchange holes maximum to insert 8 outside line optical fiber, supposes to insert altogether 8 outside line optical fiber, still is designated as A01～A08 successively.One end of every outside line optical fiber is fixed in the circuit optical fiber linker 3 separately, so the circuit optical fiber linker 3 of fixed outer circuit optical fiber one end should be provided with 8 altogether.
In order to realize the exchange of any two outside line optical fiber, this fiber full-switching equipment also comprises drive unit and searches device (not shown among Fig. 4), when searching the target exchange hole, increased restriction in the present embodiment: search device in each self-corresponding delegation exchange hole of outside line optical fiber that needs exchange with respect to embodiment one, search in a side that is used to insert the circuit optical fiber linker and be idle and be positioned at two exchange holes of same row, and a pair of cord circuit fiber optic links device that the same row at two exchange hole places that this is searched are corresponding is unoccupied, with described two exchange holes that find as the twin target exchange hole.Because two outside line optical fiber are realized optical path by a cord circuit optical fiber among the utility model embodiment, thereby reach the purpose of exchange, and in the present embodiment again further a pair of cord circuit fiber optic links device of the fixing every cord circuit optical fiber of restriction can only be inserted in the exchange hole in the row of this cord circuit optical fiber correspondence, so in the present embodiment when searching the twin target exchange hole for two outside line optical fiber that need exchange, must guarantee at first that this lays respectively on the row of these two outside line optical fiber correspondences to the target exchange hole, but also to guarantee to be positioned at same listing, in addition owing to one list and have only a cord circuit optical fiber to use at most, therefore will guarantee that also this cord circuit optical fiber to target exchange hole column correspondence is unoccupied, it is unoccupied perhaps can be expressed as pairing a pair of cord circuit fiber optic links device.Search device after finding the target exchange hole that meets the demands, two circuit optical fiber linkers that drive unit drives fixing two outside line optical fiber that need exchange move to target exchange place in the corresponding row separately respectively, and insert wherein from a side that is used to insert the circuit optical fiber linker, drive this a pair of linker of fixing cord circuit optical fiber two ends and move to described twin target exchange hole place respectively target exchange hole column correspondence, and insert wherein from a side that is used to insert cord circuit fiber optic links device, an end that is fixed on two outside line optical fiber in two circuit optical fiber linkers that are inserted in the target exchange hole like this docks with the two ends of cord circuit optical fiber in the cord circuit fiber optic links device that is inserted into from opposite side the target exchange hole respectively.
With a concrete example effect of searching device and drive unit is elaborated below, for example, realize the exchange between outside line optical fiber A02 and the A05 if desired, search device and at first in the 2nd row and the 5th row exchange hole, seek unappropriated two exchange holes of cord circuit fiber optic links device that are in same row and this row correspondence, in the searching process, can on the 2nd row and the 5th row, search, will find unappropriated two exchange holes of the cord circuit fiber optic links device that satisfies the column correspondence as the target exchange hole for the first time since the 1st row.For example, find the exchange hole (being designated as 11g) that is in the 2nd row the 4th row among Fig. 4 and be in exchange hole (being designated as 11h) that the 5th row the 4th is listed as the twin target exchange hole.The linker 32 of drive unit driving fixed outer circuit optical fiber A02 moves on to exchange hole 11g place then, and from being used for inserting the side insertion exchange hole 11g of circuit optical fiber linker, the linker 35 that drives fixed outer circuit optical fiber A05 moves on to exchange hole 11h place, and from being used for inserting the side insertion exchange hole 11h of circuit optical fiber linker.And the corresponding cord circuit optical fiber 2d of the 4th row, the fixing two ends of cord circuit optical fiber 2d among cord circuit fiber optic links device 4g and the 4h.Drive unit also drives cord circuit fiber optic links device 4g and 4h moves to target exchange hole 11g and 11h place respectively, and inserts wherein from a side that is used for cord circuit optical fiber.When cord circuit fiber optic links device 4g and 4h are inserted into respectively among exchange hole 11g and the 11h, and after circuit optical fiber linker 32 and 35 is inserted into exchange hole 11g and 11h respectively from opposite side, the end of cord circuit optical fiber 2d among the end of outside line optical fiber A02 in the circuit optical fiber linker 32 and the cord circuit fiber optic links device 4g docks, the other end of cord circuit optical fiber 2d among the end of outside line optical fiber A05 in the circuit optical fiber linker 35 and the cord circuit fiber optic links device 4h docks, like this, form optical path by a cord circuit optical fiber 2d between outside line optical fiber A02 and the A05, can intercourse light signal.It is no longer idle in a side that is used to insert the circuit optical fiber linker to have inserted the exchange hole 11g of circuit optical fiber linker and 11h.And after cord circuit fiber optic links device 4g and 4h be inserted into the target exchange hole, the state-transition of cord circuit fiber optic links device 4g and 4h was occupied.
Need to prove that those skilled in the art should be understood that the number of exchange hole in the present embodiment can adjust according to the maximum outside line number of fibers that this complete exchange equipment can insert.In order to realize to realize simultaneously exchanging in twos by the maximum outside line optical fiber that inserts, then cord circuit optical fiber should have half of the maximum outside line number of fibers that inserts at least, because every corresponding row exchange hole of cord circuit optical fiber, therefore the columns of exchange hole should equal half of line number at least on the power board, could realize that the while exchanges in twos between the outside line optical fiber of the maximum number that can insert.
