The major difference between the two is that light waves are much shorter than radio waves. Author: Dr. Rüdiger Paschotta. However, over time when the system starts to age, the OSNR margin can be lost, and the optical system can then run under a poor OSNR condition. Because the specific rotation depends upon the temperature and upon the wavelength of the light, these quantities also must be specified. The definition of optical is having to do with sight or light. WhatsApp. Updates? What made you want to look up optical?
