Microsoft (MSFT) has called for the US administration to halt FCC plans to stop imports of new models of optical transceivers from China, Reuters reports citing sources.

Technology firms lobbying against import restrictions on Chinese components follows a familiar pattern in the US-China trade and security conflict: regulators frame network equipment as a national security exposure, while the firms that buy the hardware at scale argue supply chains cannot be re-routed quickly. Optical transceivers are a chokepoint input for data centre buildout, so the immediate transmission channel runs through hyperscaler capex economics and the listed networking and component suppliers that compete with or source from Chinese producers, not through the software franchise itself. Episodes of this kind have tended to play out over months: an initial regulatory proposal, an industry comment and lobbying phase, and then a decision that is often narrowed, delayed, or paired with carve-outs, rather than imposed as drafted. The actors' prior form is consistent: security agencies have steadily expanded covered-equipment lists in past cycles, while large US tech buyers have repeatedly and sometimes successfully sought exemptions or longer lead times. What is worth watching next is whether other hyperscalers and equipment makers file in the same direction, and whether the agency signals any modification to scope or timing before the rule takes effect. As a sourced report of lobbying rather than a policy decision, the signal is about the shape of the eventual rule, not a change in it.
