** Shares of U.S. photonics firms gain in premarket trading after Reuters reported the U.S. was drafting a ban on Chinese data center devices
** The ban would curb U.S. imports of new models of Chinese data center components, an attempt to limit Chinese tech into U.S. industries 
** Shares of Applied Optoelectronics AAOI.O jump 17.5%; co provides fiber-optic networking products 
** Makers of optical-technology - critical for transmitting vast amounts of data at high speeds between servers - Lumentum LITE.O and Coherent COHR.N gain 11.8% and 17.5%, respectively 
** Both LITE and COHR have a $2 bln investment from AI bellwether Nvidia NVDA.O
** However, the move could still be modified or shelved by the U.S. FCC
