![]() (d) Enterprise connectivity: FSO systems are easily installable. It is also used to bypass local-loop systems of other kinds of networks. FSO can be used to solve such problem by implementing it in the last mile along with other networks. (c) Last-mile access: to lay cables of users in the last mile is very costly for service providers as the cost of digging to lay fiber is so high and it would make sense to lay as much fiber as possible. It is a network which is known to provide access to consolidated, block level data storage. (b) Storage Area Network (SAN): FSO links can be used to form a SAN. These are described below in detail: (a) Outdoor wireless access: it can be used by wireless service providers for communication and it requires no license to use the FSO as it is required in case of microwave bands. ApplicationsįSO communication link is currently in use for many services at many places. (e) Mean time between failures (MTBF) of system should be more than 10 years. (d) FSO system should have the ability to operate over wide temperature range and the performance degradation would be less for outdoor systems. (c) An overall system design should have small footprint and low power consumption because of its maintenance. (b) For high speed FSO systems, high speed modulation is important. Īn effective FSO system should have the following characteristics : (a) FSO systems should have the ability to operate at higher power levels for longer distance. FSO is a LOS (line of sight) technology, where data, voice, and video communication is achieved with maximum 10 Gbps of data rate by full duplex (bidirectional) connectivity. ![]() It has been in existence from 8th century but now is more evolved. FSO communication is not a new technology. FSO system consists of an optical transceiver at both ends to provide full duplex (bidirectional) capability. Working of FSO is similar to OFC (optical fiber cable) networks but the only difference is that the optical beams are sent through free air instead of OFC cores that is glass fiber. There is no requirement of the optical fiber cable. IntroductionįSO (free space optics) is an optical communication technology in which data is transmitted by propagation of light in free space allowing optical connectivity. Different studies on weather conditions and techniques employed to mitigate their effect are discussed in this paper. The transmission in FSO is dependent on the medium because the presence of foreign elements like rain, fog, and haze, physical obstruction, scattering, and atmospheric turbulence are some of these factors. ![]() There are many advantages of FSO like high bandwidth and no spectrum license. This system can be used for communication purpose in hours and in lesser economy. Medium can be air, outer space, or vacuum. FSO is a communication system where free space acts as medium between transceivers and they should be in LOS for successful transmission of optical signal.
