Application and advantages of FSO?

By Admin on


  • Telecommunication and computer networking

  • Point-to-point LOS links

  • Temporary network installation for events or other purpose as disaster recovery

  • For communications between spacecraft, including elements of satellite constellation

  • Security applications

  • Military application: (its potential for low electromagnetic emanation when transferring sensitive data for air forces)

  • Metro network extensions: carriers can deploy FSO to extend existing metropolitan area fiber rings, to connect new networks, and, in their core infrastructure, to complete SONET rings.

  • Enterprise connectivity: the ease with which FSO links can be installed makes them a natural for interconnecting local area network segments that are housed in buildings separated by public streets or other right-of-way property.

  • Fiber backup: FSO may also be deployed in redundant links to backup fiber in place of a second fiber link.

  • Backhaul: FSO can be used to carry cellular telephone traffic from antenna towers back to facilities wired into the public switched telephone network.

  • Service acceleration: FSO can be also used to provide instant service to fiber-optic customers while their fiber infrastructure is being laid.

  • Last-Mile access: In today’s cities, more than 95% of the buildings do not have access to the fiber optic infrastructure due to the development of communication systems after the metropolitan areas. FSO technology seems a promising solution to the connection of end-users to the service providers or to other existing networks. Moreover, FSO provides high-speed connection up to Gbps, which is far more beyond the alternative systems.


  • Long distance up to 8 km.

  • High bit rates speed rates: the high bandwidth capability of the fiber optic of 2.5 Gbps to 10 Gbps achieved with wavelength division multiplexing (WDM). Modern systems can handle up to 160 signals and can thus expand a basic 10 Gbit/s system over a signal fiber pair to over 1.6 Tbit/s.

  • Immunity from electromagnetic interference: secure cannot be detected with RF meter or spectrum analyzer, very narrow and directional beams

  • Invisible and eye safe, no health hazards so even a butterfly can fly unscathed through a beam

  • Low bit error rates (BER)

  • Absence of side lobes

  • Deployment of FSO systems quickly and easily

  • No Fresnel zone necessary

  • Low maintenance (Practical)

  • Lower costs as compared to fiber networks (FSO costs are as low as 1/5 of fiber network costs).

  • License-free long-range operation (in contrast with radio communication)
