US curbs on Chinese optical modules cloud Taiwan suppliers despite LMOC revenue record

<p class="P1" data-sourcepos="7:1-7:551;187-737">The US Federal Communications Commission is reportedly drafting rules to prohibit imports of new Chinese optical transceiver modules, with the measures targeted for publication and implementation in 2026, drawing close market attention. Industry sources expect US suppliers Coherent and Lumentum to be the principal beneficiaries if the restrictions proceed. However, both companies produce their continuous-wave lasers in-house, meaning Taiwanese optical-communications suppliers may gain redirected orders but could still face near-term disruption.
