Only the frequency of the communications carrier. Microwaves are electromagnetic radiation in the frequency range of 3 gigahertz to 300 gigahertz. Electromagnetic radiation above those frequencies are considered "optical" even though you can see only a small percentage of them with your eyes.
Microwave transmission is a high-frequency radio wave transmitted through the air. Fibre-optic cables are a very thin glass fibre along which infra-red or laser light is transmitted.
