Coherent ODSP Chips
Silicon-proven coherent optical DSP for 400G, 800G transport, and extending to 1.6T
SparkGrid's Coherent ODSP family delivers best-in-class adaptive equalization, high peformance FEC and flexible framing in a single chip — ready for integration into pluggable modules, line cards, and co-packaged optics platforms.
Purpose-Built Coherent DSP Silicon
The SparkGrid ODSP series is a family of coherent optical digital signal processors designed for the full spectrum of transport applications — from 400G DCI to 800G long-haul transmission. Each device integrates the complete coherent DSP pipeline and flexible client protocol adaptation. It covers full signal compensation and forward error correction functions in a single die, delivering ultra-low power performance.
800G+ per Wavelength
Single-carrier 800G transmission with dual-polarization, up-to-16QAM modulation and probabilistic constellation shaping, enabling ultra-high fiber capacity for high-speed optical transport.
Low Power Operation
Optimized DSP architecture reduces power consumption by over 20% against mainstream industry solutions, perfectly suited for high-density AI data centers and DCI interconnection scenarios.
Advanced DSP Equalisation
Supports real-time compensation of chromatic dispersion, PMD, SOP and PDL. Covers full scenarios including Long-Haul, ZR+, ZR and LR, adapting to complex and variable fiber link conditions.
High-Performance FEC
Advanced FEC decoding algorithm improves system OSNR margin, enhances link robustness and effectively extends optical transmission reach.
Adaptive OAM
Supports adaptive MAC frame management and insertion, link monitoring & reporting, and ultra-fast service self-healing.
Multi-Mode Unified Platform
Integrated multi-modulation and multi-FEC modes support transmission distances from 20km to 2000km, covering LR, ER, ZR, ZR+, Metro, LongHaul and ISL application scenarios.
