The deployment resulted from COBEE's need to ensure transmission and control of the PLC and SCADA control systems networks, which are indispensable for electric al power generation and transport networks, while enabling value-added services such as subsidised public telephony and data.
Connecting more than 15 hydro-electric generating sites, COBEE's network is based on a drop-and-insert system. It brings telemetry transport and control to energy systems, data access connectivity to Ethernet networks and public telephony services to areas of the country where they have been unavailable until now. An added benefit of this solution is that it enables technical and humanitarian assistance to be extended to rural communities and localities that are difficult to access geographically.
In addition, the Ethernet switches connected to the Optimux-XLE1 optical multi-plexers concentrate video surveillance applications from the power generating stations. These are transported over the fibre network in tandem with other applications, which provides an additional level of security in preventing network failure and minimising downtime.
Despite the harsh climatic conditions and the severe electromagnetic radiation that affect the region in which the RAD equipment is now operating, the Optimux units coexist in a relatively aggressive environment, and meet required standards, interacting fully with adjacent application systems.
