Embodiment four
Present embodiments provide a kind of method realizing exchanges data, for convenience of explanation, the Cluster Central Chassis that the multi-chassis cascading system that the method provides in conjunction with above-described embodiment one, embodiment two provide and the method realizing exchanges data that embodiment three provides, be external cross interconnected optical fiber with external cross interconnected equipment, and to realize exchanges data in the system shown in Fig. 5 be example, the method that the present embodiment provides is illustrated.In Fig. 5, each subscriber frame is connected with external cross interconnected optical fiber by direct-connected optical fiber, and external cross interconnected optical fiber is connected with each network board of Cluster Central Chassis inside by direct-connected optical fiber again.System schematic shown in composition graphs 5, see Fig. 6, the method flow that the present embodiment provides is specific as follows:
601: the user data of each subscriber frame, and to be intersected at external cross interconnected inside of optical fibre in corresponding external cross interconnected optical fiber by direct-connected Optical Fiber Transmission;
Wherein, because each subscriber frame is connected with external cross interconnected optical fiber respectively by direct-connected optical fiber, thus the user data of subscriber frame by direct-connected Optical Fiber Transmission in corresponding external cross interconnected optical fiber, and can intersect at this external cross interconnected inside of optical fibre.As shown in Figure 5, external cross interconnected optical fiber is the cross interconnected optical fiber of 2*2, and namely have 2 entrances and 2 outlets, each entrance is two groups of optical fiber, often organize optical fiber and comprise one to multiple optical fiber, the user data of each subscriber frame is by the direct-connected Optical Fiber Transmission entrance that extremely external cross interconnected optical fiber is corresponding.Such as, the user data that second user interface of first subscriber frame exports inputs from second group of optical fiber of first entrance of the cross interconnected optical fiber of 2*2, and the first group of optical fiber exported by the cross interconnected optical fiber of 2*2 second after external cross interconnected inside of optical fibre intersects exports.
602: the user data after external cross interconnected inside of optical fibre intersects by direct-connected Optical Fiber Transmission to each network board of Cluster Central Chassis inside;
For this step, because external cross interconnected optical fiber is connected with each network board of Cluster Central Chassis inside by direct-connected optical fiber, when the user data of subscriber frame is after external cross interconnected inside of optical fibre intersects, the user data after intersection by direct-connected Optical Fiber Transmission to each network board of Cluster Central Chassis inside.In the cross interconnected optical fiber of 2*2 as shown in Figure 5, many groups optical fiber of each entrance by cross-assignment to each outlet, each outlet optical fiber forms by from each incoming fibers, each interface on each network board of each Cluster Central Chassis inside is connected with subscriber frame by the cross interconnected optical fiber of 2*2, thus can receive the user data of 2 different user frames.Such as, the user data that second user interface of first subscriber frame exports inputs from second group of optical fiber of first entrance of the cross interconnected optical fiber of 2*2, after the first group of optical fiber exported by the cross interconnected optical fiber of 2*2 second after external cross interconnected inside of optical fibre intersects exports, by direct-connected Optical Fiber Transmission to first interface of second network board of Cluster Central Chassis.

903: each network board of Cluster Central Chassis inside receives the user data of each subscriber frame by each external cross interconnected optical fiber in external intersection equipment frame;
Wherein, because each network board of Cluster Central Chassis inside is connected with the external each cross interconnected optical fiber intersected in equipment frame by direct-connected optical fiber, thus when the user data of subscriber frame is by direct-connected Optical Fiber Transmission extremely external cross interconnected optical fiber, and after external cross interconnected inside of optical fibre intersects, each network board of Cluster Central Chassis inside can receive by the user data of each subscriber frame of direct-connected Optical Fiber Transmission.As shown in Figure 8, n outlet of the cross interconnected optical fiber of n*n in external intersection equipment frame is connected with n network board of Cluster Central Chassis respectively, thus each interface on each network board of Cluster Central Chassis inside can be made can to receive user data from n subscriber frame, then can support at most k*n subscriber frame by the system after the cross interconnected Fiber connection of n*n.
Alternatively, when user data due to subscriber frame is transmitted by direct-connected optical fiber, transmit in the form of light, in order to enable the user data of subscriber frame transmit in farther distance, the method that the present embodiment provides also comprises the process of the user data of subscriber frame being carried out opto-electronic conversion.During concrete enforcement, the operation of opto-electronic conversion is realized by external optoelectronic conversion equipment, therefore, the user data of each subscriber frame is after opto-electronic conversion is carried out in external photoelectric conversion device inside, external cross interconnected device interior in external intersection equipment frame intersects, and the user data after intersecting carries out electro-optic conversion in external photoelectric conversion device inside; Wherein, this external optoelectronic conversion equipment can be placed in external intersection equipment frame with external cross interconnected equipment in the lump, and can be placed on outside external intersection equipment frame, the present embodiment does not do concrete restriction to this yet.
