Upgrading Argentina's 500 kV Transmission Network: From Legacy SDH Microwave to Hybrid TDM/Packet Systems for Enhanced Reliability
In the early 2000s, Argentina deployed its first optical Synchronous Digital Hierarchy (SDH) backbone to support a 500 kV extra-high voltage (EHV) transmission system. Remote nodes beyond fibre reach were connected via a microwave system using SDH radio at Synchronous
