It utilizes a 16-wavelength DWDM architecture, with each SerDes channel operating at 112G, and integrates Qualcomm Technologies' 112G PAM4 optical SerDes chiplet.\n\nLightmatter stated that this platform offers up to 8 times higher bandwidth density per fiber compared to existing NPO and CPO solutions, moving towards I/O exceeding 100Tbps per package. Related products have already been provided to leading customers for testing and will be showcased at OFC 2026 in Los Angeles from March 15 to 19.",
