Space optics technology12/7/2023 To create an S-FSO, the communication system will usually be equipped with data fragmentation multipath transmission or shortened to DFMT. The term that is often used to talk about this topic is secure free space opticals (S-FSO). Data SecurityĪny information that is transmitted also needs data security. SCM allows limiting wavelength resources so as to make spectrum more efficient. An example of a new FSO is an FSO equipped with Subcarrier Multiplexing (SCM). Metropolitan will require free space optics subsystems technology. The performance gain that many companies want is to be able to reach further and also create circuits capable of delivering faster transmissions. These subsystems allow companies to produce FSOs with higher performance and lower costs. You already understand the mechanism of Free Space Optics and now is the time to learn about Free Space Optics Subsystems. An optical amplifier is useful for increasing optical intensity.įree Space Optics Free Space Optics Subsystems The data coming from the source will be modulated and the laser beam will be passed through the optical amplifier. The transmitter section has a special design in the form of a laser diode, optical amplifier, modulator, and beamforming optics. Despite the contention between the two companies that issue FSO hardware, it’s important that we understand how it works.Īccording to the Hyperiontechs website, FSO utilizes lasers for data transmission through the air. While the stronghold that supports FSO with a wave of 800 – 980 nm provides an argument that the wavelength is considered the best. Opponents expressed the opinion that waves as large as 1550 nm can have a negative impact on eye health. One side supports the use of FSO with a band of 1550 nm and the other side opposes the use of lasers with a wavelength of 1550 nm. The Cablefree website, explains that there are at least two arguments regarding the safety of lasers with these waves. The first type of hardware can operate in the band around 800 nm and the second hardware will be able to operate at 1550 nm. How It Works?įSO technology available today can be divided into two based on the hardware. At a glance, FSO works similarly to wireless keyboards, TV remote controls, and IRDA on cellular phones. Basically, this technology emits lasers into space to transmit information. Reporting from Gigabit Wireless, FSO has other names, such as Infrared Laser or Optical Wireless. In fact, FSO stands for Free Space Optics. Many people do not understand the term FSO so they do not know whether FSO is optical or wireless communication technology.
