An optocoupler, also known as an optoisolator or photocoupler, is an electronic device made up of an LED emitter combined with a photodetector, separated from each other in proximity. There are many types of photodetectors, most of which are variations on a photodiode or phototransistor.

NewSpace is an approach that focuses on lowering the barriers to entry to space industry, by providing cheaper access to space… One of the major characteristics of the NewSpace era is the fundamental shift from an industry which was heavily dependent on government agencies to a more agile and an independent private sector that relies on innovation, working with much smaller budgets than the early space industry.
