The Marvell Ara PAM4 DSP is a next generation solution for GenAI and cloud datacenter interconnects utilizing pluggable transceivers. LOWELL, MA – March 17, 2026 – MACOM Technology Solutions Inc. (“MACOM”), a leading supplier of semiconductor products, today announced the availability of its new 448G PAM4 modulator drivers, designed to accelerate time-to-market for next generation 1. Ara features eight 200Gbps/channel PAM4 host electrical interfaces, and an octal 200Gbps/lane PAM4 optical interface with integrated high-swing laser-modulator. The HT-100GD-CXX series QSFP28 100G DWDM PAM4 LC QSFP28 DWDM Transceiver module is designed for use in duplex optical data communications. This module is designed for single mode optical fiber and operates at a data rate of 100Gbps at the nominal DWDM wavelength from 1528. 50nm as. The variety of currently available 100G DWDM transceivers comprise coherent ACO (Analog Coherent Optics) and DCO (Digital Coherent Optics). The latter features an integrated DSP with advanced SD-FEC, HD-FEC technology. released 50G PON three-mode Combo OLT miniaturized optical device, which is MPM (built-in combined wave) 3-generation wave division mode coexistence, that is, G/XG (S)/50G three-mode MPM.
