Summary of Conference Call on Optical Interconnect Technologies Industry Overview - The discussion focused on optical interconnect technologies, specifically AOC (Active Optical Cable), LPO (Linear Passive Optical), NPO (New Passive Optical), and CPO (Coherent Passive Optical) [1][2][17]. Key Points and Arguments AOC Technology - AOC is defined as a fixed optical fiber module suitable for short-distance multimode transmission, particularly within 50 meters, as used by Google [2][19]. - AOC's cost structure was analyzed, with 800G AOC priced over a thousand dollars and 400G AOC costing several hundred dollars [2][19]. - AOC is expected to support 1.6T transmission capabilities in the future, although current limitations exist [20]. LPO Technology - LPO modules differ from traditional optical modules by omitting DSP (Digital Signal Processor), utilizing linear drive technology, and achieving a transmission distance of up to 500 meters [4][19]. - LPO is projected to see shipments of three to four million units in 2023, potentially doubling by 2027 due to demand from major clients like Google, Microsoft, and Meta [5][19]. - The combination of AOC and LPO is anticipated for different application scenarios, with AOC for short-distance interconnects and LPO for longer distances [19]. NPO Technology - NPO optical engines are compact, low-power, and do not require an external shell, making them suitable for high-density applications like AI accelerators [7][10]. - NPO technology is expected to mature and be sold to cloud providers and equipment manufacturers, with significant market potential [9][23]. - The cost of NPO components, such as the optical engine, is estimated to be around $35 to $40 per unit [26]. Market Dynamics - The market for 800G optical modules is currently in mass production, while 1.6T modules are still in early development, expected to mature in two to three years [5][6][22]. - The supplier landscape is concentrated, with limited opportunities for new entrants, particularly in the TIA (Transimpedance Amplifier) and driver chip sectors dominated by companies like Marvell [6][22]. Technical Challenges - The discussion highlighted challenges in the 200G optical module market regarding transmission distance and industry maturity [3]. - The transition from NPO to CPO technology was noted as technically feasible but with potential challenges in product form factor [9][23]. Future Trends - The integration of optical communication technologies in data centers is expected to grow, with a focus on reducing costs and power consumption while improving system latency [10][14]. - The potential for NPO to replace existing GB300 systems was discussed, contingent on its maturity and performance improvements [25]. Additional Important Content - The role of silicon photonics in NPO technology was emphasized, with key suppliers identified as Group, Tog, and TSMC [15][28]. - The discussion also touched on the advantages of glass substrates in CPU applications, highlighting their cost-effectiveness compared to ceramic and PCB substrates [27]. - The collaboration between Google and various suppliers for LPO technology was noted, with initial production expected from companies like Xuchuang [28]. This summary encapsulates the critical insights and developments in the optical interconnect technology sector as discussed in the conference call.
