A BRIEF INTRODUCTION TO FREESPACE OPTICAL COMMUNICATIONS

Originally conceptualized in the 1960s, a Free Space Optical (FSO) network uses high powered lasers to transmit large amounts of data and use air as a medium to transmit its payloads. Numerous commercial FSO solutions currently available for deployment feature optical hardware that can support Gbps throughput rates.

 

Optical spectrum is also license-free, obfuscating the need to obtain permissions to use optical channels. Considerable savings on spectrum licensing fees are possible using FSO networks in comparison to other wireless Radio Frequency (RF) based technologies.

 

Optical beams are immune to interference from electromagnetic fields, making the technology highly suitable for co-existence with current wireless deployments. Currently available hardware is also highly capable at mitigating mutual interference among multiple light sources with the same specifications. Free Space Optical (FSO) communications technology is also more affordable to install and maintain due to its RoW free nature, as well as the fact that key components are far less costly to repair and replace.

Why do you need Free-Space Optics?

  • To solve “last mile” problem

  • To organize wireless high-speed information channels

  • To create network between the offices across the city

  • To make a wireless network channel in a places, where it’s impossible to use cable

  • To backup the fiber cable

  • To install temporary  high-speed information channels

GODSPEED

Laser communications are extremely fast. They can transfer gigabits of data within milliseconds. The comparison to its closest competitor, mmwaves is not even close. The mmwave transmitted 40Gbps and Laser transmitted 13160 in the world record attempt

SECURE

We do not want our messages to be read or intercepted by anyone. We need our privacy in this online world even in the end mile connectivity. The current RF solutions does not offer that. Lasers offer a level of security that is seeing it used increasingly for future developments in the establishment of impenetrable and impossible to hack networks such as dedicated, private data networks owned by individual organizations.

LICENCE FREE 

In the RF communication, the satellites have to obtain permission from each country you're providing service to with a huge cost part. The wait time again is a burden. Altogether you have to wait min 2 years to obtain a license and launch the satellite.

Laser communication is not regulated by the International Telecommunication Union and it can be used without restrictions and does not require costly licenses. The reason for this is that its inherent small beam size avoids interference issues and renders any restrictive regulation in the future highly unlikely.
