The Optical Communication System of the Wild Internet of Things for One-to-Multi-Points

With the development of the wild Internet of things , Because of the many benefits of laser communications, laser communications network as Internet of things important means of optical networks has become an inevitable trend and urgent demand. This paper designed the 150mm optical main diameter, Laser divergence angle of 1mrad multipoint communication system. Mainly using the splitter splitting and frequency division multiplexing combined, through optical design and frequency shift keying binary method, The purpose is achieve that received the same optical signal of six channels at the same time.The laser communications systems for the internet of things development of a new device.
