1、 Core technology for complete production of 800G optical module (1) Core architecture and packaging process (two mainstream routes for mass production)
1. COB board chip packaging (mainstream in AI data centers, preferred for ultra high speed), full name Chip On Board, 800G core upgrade process: 1 Cancel the traditional TO-CAN split tube shell and directly mount the EML laser chip, PD detector, and TIA transimpedance amplifier on the high-frequency high-speed PCB/soft hard combination board with bare chips;
2. Short distance interconnection using gold/copper wire bonding greatly reduces high-frequency insertion loss and signal crosstalk, ensuring the integrity of 112Gbps single channel PAM4 signals
3. Paired with roll to roll R2R-FPC flexible interconnect board and ultra-thin soft hard bonding board to reduce size and power consumption (overall power consumption ≤ 15W);
4. Equipped with submicron level six axis fiber coupling alignment, high coupling efficiency and strong optical path stability
2. BOX box type split package (backup for long-distance coherent optical modules) independent metal tube packaging for discrete devices, airtight packaging filled with inert gas, moisture-proof and temperature resistant, mostly used for 800G long-distance coherent transmission (16QAM/PS-16QAM modulation), with the advantages of strong maintainability and good environmental tolerance. Short distance computing power centers are gradually being replaced by COB
3. Cutting edge advanced packaging: CPO co packaged Optics 800G to 1.6T iterative core technology, optical engine and switch ASIC chip integrated on the same substrate, extensively using high-frequency ceramic substrates, ultra-thin FPC soft boards, and micro high-density wiring, completely solving the bottleneck of high-speed signal routing loss.
（2） Optoelectronic chips and modulation technology
1. Optical chips: InP indium phosphide based EML electroabsorption modulation laser, DFB distributed feedback laser, high-speed PD photodetector; two Electronic chips: 7nm/5nm DSP digital signal processing chip, TIA transimpedance amplifier, laser driver chip;
3. Modulation format: PAM4 four level pulse amplitude modulation, single channel 112Gbps, 8-channel beamforming achieves a total bandwidth of 800G; The long-distance version adopts 800G PS-16QAM 4. Error correction algorithm: RS-FEC strong forward error correction, and the error rate is optimized to the level of 10 ⁻¹⁵.
1. Rigid high-frequency high-speed PCB board • Board: Megtron 6/Megtron 7, Rogers, Taconic low DK/Df low loss high-speed board, process: 8-12 layers of high-order HDI blind buried holes, LDI laser direct imaging, minimum line width of 3mil, strict control of differential impedance of 100 Ω± 5%, single end 50 Ω± 3%; Surface treatment: ENEPIG nickel palladium gold (preferred for automotive/optical module reliability), suppresses high-frequency oxidation contact loss. Solve the problem of high-speed interconnection without connectors between internal boards of the module;
4. Multi process composite compatibility capability (highlight of Super Sheng differentiation): On the basis of roll to roll, add our own mature processes:
Thick copper current carrying FPC (3oz/4oz inner layer thick copper), used for high current flexible power boards in new energy vehicle electronic control;
Buried copper, buried resistance and capacitance embedded flexible board;
Localized aluminum/metal based composite heat dissipation FPC;
Combining software and hardware, HDI blind buried hole FPC achieves integrated power and signal.
5、 Landing application scenarios (Chaosheng's main track)
1. AI computing power/data center communication 800G/1.6T optical module flexible FPC, switch high-speed interconnect flexible ribbon cable, GPU computing power card carrier board flexible jumper, CPO optoelectronic co packaging flexible interconnect board;
2. New energy vehicle on-board OBC, DC-DC flexible power thick copper soft board, BMS battery acquisition cable, on-board display screen pivot FPC, seat/radar sensor flexible circuit;
3. Consumer electronics&smart terminal foldable screen mobile phone hinge FPC, TWS headphone internal soft board, smart watch/wristband wearable sensor flexible circuit board;
4. Replacement of ultra long flexible wiring harnesses for industrial equipment and medical aerospace equipment, ultra-thin soft boards for medical implants, and lightweight high-density interconnect flexible boards for aerospace.
