Embodiment 1

[0082] Such as Figure 5a , 5b , 5c shows: this embodiment realizes the design of 64-slot line card, single line card 800G bandwidth, and the maximum capacity of the system is 51.2T.

[0083] Adopt double-layer switch card structure. The single line card is 800G, and the single physical connection rate is 25G. A single line card needs 48 channels to transmit data. Considering protection, a total of 64 physical channels are required. According to structural constraints, the number of switching cards can be selected as 8, and the 6+2 protection mode is adopted . The 64 channels of the line card are allocated to 8 switch cards, and each switch card has 8 channels. The cable box and line card interconnection sockets (components 3 and 10) use 4x4pairs and support 8 channels. The line card and switch card interconnection sockets (components 2 and 9) use 4x4pair and support 8 channels. The cable box and the switch card interconnection socket (components 7 and 8) use a 4x8 pair a...

Embodiment 2

[0101] This embodiment realizes the design of 72-slot line cards and 1T bandwidth of a single line card, and the maximum capacity of the system is 72T.

[0102] A three-layer switching card structure is adopted. The single line card is 1T, and the single physical connection rate is 25G. A single line card needs 60 channels to transmit data. Considering protection, a total of 72 physical channels are required. According to structural constraints, the number of switching cards can be selected as 12, and the 10+2 protection mode is adopted . The 72 channels of the line card are allocated to 12 switch cards, and each switch card has 8 channels. The cable box and line card interconnect sockets (components 3 and 10) use 4x8 pairs, supporting 16 channels. The line card and switch card interconnection sockets (components 2 and 9) use 4x4pair and support 8 channels. The cable box and the switch card interconnection socket (components 7 and 8) are 8x8pairs, supporting 32 channels. T...

Embodiment 3

[0120] This embodiment realizes the design of 80-slot line cards and 1T bandwidth of a single line card, and the maximum capacity of the system is 80T.

[0121] Adopt four-layer switch card structure. The single line card is 1T, and the single physical connection rate is 25G. A single line card needs 60 channels to transmit data. Considering protection, a total of 72 physical channels are required. According to structural restrictions, the number of switching cards can be selected as 12, and the 10+2 protection mode is adopted . The 72 channels of the line card are allocated to 12 switch cards, and each switch card has 8 channels. The cable box and line card interconnection sockets (components 3 and 10) use 6x8 pairs and support 24 channels. The line card and switch card interconnection sockets (components 2 and 9) use 4x4pair and support 8 channels. 8x12pairs are used for the interconnection sockets (parts 7 and 8) of the cable box and the switch card, supporting 48 channe...

Abstract

The invention provides a backplane structure and a centralized switching device. The backplane structure comprises wire cards disposed on the front side of the backplane and switching cards disposed on the back side of the backplane. The above technical scheme solves a problem that a backplane in the prior art is not good in transmission performance and small in design space so as to satisfy a requirement of a high-speed signal for path loss and enlarge the design space of a single backplane.

Description

technical field [0001] The invention relates to the field of centralized cross-connect backplanes, in particular to a backplane structure and centralized switching equipment. Background technique [0002] Centralized switching equipment is mainly used in fields based on Optical Transport Network (OTN for short), Packet Transfer Network (PTN for short), and Internet Protocol (IP for short). With the rapid development of Internet and 3G\4G services With the development of the market, the demand for dispatching capacity of switching equipment is increasing. At present, the existing technology of centralized cross-connect devices mainly implements high-speed interconnection through backplane wiring. The latest large-capacity backplane implementation in the industry is a belt-shaped design, see the attached Figure 1a and 1b . [0003] Figure 1a and 1b shows a single-sided three-layer device structure, double-sided six-layer capacity is doubled, and the structure on the othe...
