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.

All mirages are optical illusions but all optical illusions are not mirages.

The difference between optical and non optical is the way the drive in the DVD reads the disk. Optical is a better and more higher quality reader. So the picture is much better.
light is must for optical microscope while is not necessary for nonn optical one
definition of optical satellite communication
The electrical bandwidth refers to the frequency range that the electronic components in the communication system can handle, while optical bandwidth refers to the frequency range that the optical fiber can transmit. The relationship between the two bandwidths is important in ensuring that the data transmission is efficient and reliable. Matching the electrical and optical bandwidths helps to avoid signal degradation and distortion in the communication system.
Optical remote sensing is affected by cloud covers , rain etc but microwave remote sensing is not.However the optical sensors always need sun as a source of illumination while active microwave sensors don't need.
A line-of-sight communication medium refers to a transmission method where the sender and receiver must have a clear, unobstructed path between them. Examples include optical fiber, microwave links, and free-space optical communications. These mediums rely on direct visibility for effective signal transmission, making them suitable for applications like satellite communications and certain wireless networks.
