100g Optical Module Technology Stacking
It features low power consumption, high port density, compact size, and cost efficiency. This article reviews QSFP28 module types and key WDM technologies like CWDM and DWDM. Breakout-capable 100G modules are optical transceivers or cables designed to split a single 100Gbps port into multiple lower-speed channels, typically four 25Gbps or 10Gbps links. Marvell's industry leading Porrima™ 100G PAM4 DSPs, which were added to its networking portfolio through the recent Inphi acquisition, transmits 100G data on a single wavelength. The Porrima 100G DSP platform has been in production since 2019 and is the industry's best-selling solution. In this paper, in order to support application for multiple 100G transmissions on one node and do centralized management of multiple physical devices, we further propose a novel scheme to implement multiple 100G transmissions based on stacking technology.
