Optical stocks

Optical networking companies, which manufacture optical transceivers and components that convert electronic data into light signals and transmit them through fiber-optic cables. Many data centers are now upgrading their older copper wires, which are too slow and generate too much heat to handle the latest cloud and AI applications, to faster fiber-optic components.
