Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0019] Such as Figure 1 to Figure 3 Shown is a specific embodiment of a fiber-optic composite board of the present invention, including a PCB board and an optical layer. The PCB board is divided into an upper PCB board 1 and a lower PCB board 2. In this embodiment, the upper PCB board is mechanically pressed The PCB board and the lower PCB board are integrated into a photoelectric composite board as a whole; the upper PCB board 1 and the lower PCB board 2 can be a radio frequency backplane with surface mount components on one side for transmitting radio frequency signals, and a high-speed backplane for transmitting high-speed signals The backplane or the high-speed radio frequency integrated board used to transmit radio frequency signals and high-speed signals, the upper PCB board 1 and the lower PCB board 2 are butt-bonded by doubl...

The invention relates to an optical fiber type photoelectric composite board comprising multiple layers of PCBs which are fixedly connected into a whole in a stacked mode, the PCB on the outer side is any one of a radio frequency backboard, a high-speed backboard and a high-speed radio frequency integrated board with surface-mounted components on the single side, and a cavity for containing and fixedly connecting an optical layer is reserved between the PCBs on the outer side so that optical signals can be transmitted conveniently. The optical layer comprises at least one substrate and an optical fiber fixed on the substrate to form a stable light channel. Compared with the prior art, radio frequency signals, high-speed signals and optical signals are transmitted in an integrated mode, the signal density is improved, the trouble of bundling and fixing radio frequency lines and optical cables is avoided, the size of photoelectric equipment is reduced, manufacturability and materials are relatively mature, and the optical fiber type photoelectric composite board can be quickly pushed to the market.
Description
technical field [0001] The invention relates to the technical field of integrated optoelectronics, in particular to an optical fiber type optoelectronic composite board. Background technique [0002] The existing common optoelectronic interconnection schemes generally use PCB boards for high-speed signals, and jumper wires for RF and optical signals. There are also separate RF backplanes or optical fiber flexible boards to transmit and process RF signals and optical signals respectively. There is no integrated optoelectronic composite board product that integrates the above three signals at the same time, so the radio frequency lines and optical cables need to be bundled and fixed, which increases the volume of the optoelectronic equipment and cannot further increase the signal density. Contents of the invention [0003] In view of the above-mentioned technical problems that high-speed signals, radio frequency, and optical signals cannot be integrated, which leads to the n...
