After years of R&D iteration on PIC-based high-speed transceivers, the 1.6T pluggable module is stepping from lab validation into mass production for AI/800G+ hyperscale data center interconnection. This exploded view details all critical Intel-designed core components powering this cutting-edge solution:
✅ Transmitter PIC + Driver: Intel’s monolithic silicon photonic transmitter chip paired with dedicated 1.6T driver IC, integrating laser modulator arrays to convert high-speed electrical signals into modulated optical signals, the core of Tx optical engine.
✅ DSP (Digital Signal Processor): Custom 1.6T coherent DSP chip to complete signal shaping, equalization, FEC coding and impairment compensation, defining module transmission reach & performance boundary.
✅ Rx Side Core Components: Integrated photodiode array + dedicated transimpedance amplifier (TIA). PD array captures incoming optical signals and converts to tiny current, while TIA amplifies weak current into usable electrical input feeding back to DSP.
✅ Fiber Assembly Units: Precision Tx/Rx fiber coupling subassemblies, responsible for stable light coupling between on-chip PIC waveguides and external single-mode fiber, directly determining module insertion loss consistency. From discrete 400G/800G component layout to highly-integrated PIC-centric 1.6T architecture, silicon photonics continues to reshape cost, power consumption and density roadmap of hyperscale interconnect.
