The 100G-DR-LPO specification by the LPO (Linear Pluggable Optics) MSA defines 100 Gb/s/lane 53. 125 GBd PAM4 optical interfaces, optical links using standard single-mode fiber with up to 500 m reach, and host-module electrical interfaces for hosts with DSP. Last year, module vendors demonstrated the first 1. 6T optical modules, and this year DSP vendors looked ahead to second-generation 1. 6T modules connect a 16x100G host interface to 8x200G optics (16:8), next-generation designs will work with forthcoming. What appears as a simple vendor substitution on a spreadsheet translates to PAM4 signal degradation, EEPROM mapping failures, and thermal throttling in production. It. The Q112-400LPO-DR4 is a cost-effective module with high performance, which is optimized for AI Datacenter, supporting data-rate of 4x112Gb/s PAM4 Optical interface and 4x112Gb/s PAM4 Electrical interface. Its transmission distance is up to 500m on single mode fibers. It replaces a retimed DSP data. The Marvell® PAM4 optical DSP portfolio, including Spica™ and Nova™ DSPs, addresses the critical the need for high-bandwidth optical interconnects to power AI infrastructure.
