What it does
The bill bans federal agencies from buying optical transceivers made in China. Optical transceivers send data through light in computer networks. The ban starts right away for critical systems. Non-critical systems get five years to switch. The Commerce Department must check if the U.S. can make enough of these devices.
Who it affects
Federal agencies and the companies that sell them equipment are affected. Taxpayers may pay more if U.S.-made devices cost more. The bill also affects U.S. optical transceiver makers.
One thing to notice
The bill gives non-critical systems five years to stop buying Chinese transceivers. Agencies might buy a lot of them before the ban takes full effect.
