On the news front, according to reports, three people familiar with the matter said Microsoft has been pressing the Trump administration to abandon a plan to ban imports from China of a key component used in artificial intelligence (AI) data centers. Two sources said Microsoft was among several companies that met with officials from the White House Office of Science and Technology Policy and the National Security Council in September, and pointed out at the meeting the supply chain challenges such a ban could bring. Media reports in August said the Trump administration planned to ban imports from China of new models of optical transceivers. Such devices allow data to travel at the speed of light through fiber-optic cables within data centers.
