UTILIZATION OF SCADA’S OPTICAL COMMUNICATION LINK FOR INTER POWER STATION ACCESS , MONITORING AND CONTROL

A Fiber optics based communication is most preferred for high speed ,connectivity and real time data transfer over long distance.It also donot compromise in Video,audio and data quality thus aids to ease of real time access and monitoring at various power sub-stations.A Power company having own indigineous scada's optical fiber network can implement own Video Conferencing system .Use of optical network provides seamless integration connecting every region,states and zones leading to pro-active action whenever required.As optical fiber is immune to EMI (Electromagnetic interference) and atmospheric conditions ,it is most robust and reliable means of communication.SONET protocol implemented in optical communication can handle large amount of digital bit stream using laser or highly coherent light emitting diode .It has capacity of transporting call and data traffic without facing problem of synchronization.
