Description
Technical Field
The utility model belongs to the technical field of the communication technology and specifically relates to a but novel FPC of long-distance transmission strides backplate transmission system.
Background
With the development and wide application of technologies such as artificial intelligence, big data, distributed storage, edge computing and the like, the demands of various communication devices on high throughput and large bandwidth are more and more urgent.
Particularly with the advent of the higher single channel 112Gbps era, the industry is facing new technical solutions. To support reasonable system size, system backplane/mid-plane long distance connections typically require up to 1 m.
At 112Gbps electrical serial rate, there are two main solutions available to achieve this distance:
firstly, the traditional backplane transmission mode can be realized mainly by using advanced ultra-low-loss PCB board media and a high-performance connector, and because the lower the board of the low-loss media is, the cost is increased exponentially and explosively, the scheme is very expensive to realize and is also difficult to realize long-distance communication;
the second, the mode of backplate cable, it is the line of walking that replaces the backplate PCB in the traditional backplate scheme with the cable, because the cable has the ultralow loss characteristic, can realize long distance intercommunication, but the cable is at the assembly process of self and the in-process of doing over again, need consume very big man-hour and manpower, leads to the cost also to be high and is high, and it still exists shortcoming such as occupation space is big moreover.
Disclosure of Invention
Not enough to prior art, the utility model provides a but novel FPC of long-distance transmission strides backplate transmission system.
The technical scheme of the utility model is that: a novel FPC (flexible printed circuit) cross-backboard transmission system capable of realizing long-distance transmission comprises a backboard PCB (printed circuit board) and a plurality of daughter card PCBs, wherein a high-speed transmission channel and a low-speed transmission channel are distributed on the backboard PCB; the high-speed transmission channel comprises a flexible FPC (flexible printed circuit board) arranged on a PCB (printed circuit board) of the back plate, and two ends of the flexible FPC are welded with corresponding first connectors;
the low-speed transmission channel comprises first connectors welded at two ends of a PCB of the back plate; and the lower end of each daughter card PCB is provided with a plurality of second connectors, and the second connectors can be plugged in the corresponding first connectors.
Preferably, two ends of the flexible FPC are detachably arranged on two ends of the back plate PCB through corresponding fixing bolts.
