This is a long-range 800G ZR+ optical module that comes in a standard OSFP pluggable form factor, yet it can reach over 500km or 1000km at 800Gbps speeds. It can even be tuned to allow 400Gbps communication at up to 2500km. Using Marvell coherent DSP. Spica Gen2-T adds to the Marvell industry-leading portfolio of 800 Gbps DSPs, the most widely deployed optical DSPs in cloud data centers and AI clusters. We got a behind-the-scenes look at how this coherent optical technology. Marvell has announced the industry's first 1. Demonstrated at OFC 2025 in a 1. 6T OSFP linear pluggable optics (LPO) module, the integrated optical engine supports 200Gbps per lane across eight channels. Marvell's Spica Gen2-T 5 nm 800G PAM4 optical DSP is a transmit-only DSP solution optimized for energy efficiency in AI and cloud infrastructure interconnects.
