Optical Links

Optical links refer to the use of optical fibers or free space optics to transmit data between two points in space. Optical links are used in space and astronautical engineering to provide high-speed, reliable communication between spacecraft, ground stations, and other space-based assets. Optical links offer several advantages over traditional radio frequency (RF) communication, including higher data rates, lower power consumption, and greater resistance to interference. Optical links can also be used to provide secure communication, as the narrow beam of light used in optical links is difficult to intercept or jam. However, optical links are limited by line-of-sight requirements and atmospheric conditions, which can affect the quality and reliability of the link.
