Description
Technical field
The utility model relates to networking technology area, relates in particular to a kind of power board system that expands.
Background technology
In the basic bearer network-fiber optic network as communications, the optical fiber switching equipment is to finish the key equipment that exchanges between the optical fiber.
At present, usually need manually to on-the-spot exchange of going jumping fiber to operate and realize between the different fiber for the switching equipment in the fiber optic network, so in routine duties manually-operated workload is huge and time-consuming, therefore how to realize being exchanged between the Long-distance Control optical fiber problem of being concerned about very much for people.
In order to realize Long-distance Control, there be the scheme of photoswitch of utilizing in the prior art as the optical fiber switching equipment, some optical fiber of the one side joint input usefulness of photoswitch, some optical fiber of another side joint output usefulness, for example Fig. 1 is the synoptic diagram of the directional coupled waveguide optical switch of 4x4 of the prior art, photoswitch p1 goes up and forms the waveguide-coupled zone p11 that 4x4 arranges, the left side of photoswitch connects 4 input optical fibre P12 in Fig. 1, the input optical fibre of the top among Fig. 1 might as well be labeled as p121, light is input among the photoswitch p1 from input optical fibre P12, and from output optical fibre P13, export, might as well with among Fig. 1 the output optical fibre of below be labeled as P134.By on the p11 of the zone of the waveguide-coupled on the photoswitch p1, applying voltage signal, can control the travel path of light in photoswitch p1, thereby control light is finally exported from which output optical fibre, promptly can realize the exchange between any one input optical fibre and any one output optical fibre.Particularly, when light passes through the waveguide-coupled zone at every turn, can be by near this zone, applying the outgoing position of Control of Voltage light, for example, have two outgoing position P11a1 and P11a2 for first waveguide-coupled zone P11a among the figure, export from P11a2 by the Control of Voltage light that setting is applied on the P11a of waveguide-coupled zone, by that analogy, can make the light propagated that the direction of arrow is represented in Fig. 1 in photoswitch P1, and finally from the 4th output optical fibre P134 output, so just realized the exchange between first input optical fibre P121 and the 4th output optical fibre P134.
But because the number of input optical fibre that the number of the optical waveguide coupled regional P11 of photoswitch P1 inside and photoswitch P1 maximum can insert and output optical fibre is relevant, promptly the number when input optical fibre or output optical fibre increases the number that all must increase the optical waveguide coupled zone of photoswitch inside, and all can produce to a certain degree loss every through an optical waveguide coupled regional P11 from the light of input optical fibre input, so when the number of input optical fibre or output optical fibre is big, light also must be through could exporting from output optical fibre behind the bigger optical waveguide coupled zone of number, thereby make that the decay of output light signal strength is serious; On the other hand, because the restriction of optical switch construction and principle of work, photoswitch can only be realized the exchange between any input optical fibre and any output optical fibre, can not realize two exchanges between the input optical fibre, can not realize that promptly all are linked into any exchange between the optical fiber (comprising input optical fibre and output optical fibre) on this photoswitch, promptly can not realize " full exchange ".
In addition, be accompanied by the continuous increase of scope of the enterprise, need be linked into optical fiber on the switching equipment or other number of devices also in continuous increase, original switching equipment that outnumbers of the optical fiber on being linked into switching equipment or other equipment can be maximum during the number that inserts, and in the prior art original switching equipment being replaced with provides the more switching equipment of multiple access number.This has just caused the waste of original switching equipment.
