It functions like a router or switch in a traditional network but tailored for fiber optics. Essentially, the OLT is the brains of the FTTH network, controlling how. In-depth Analysis of Intelligent Solutions for the Distribution Automation Industry: Network Equipment Selection and Deployment Strategies Distribution automation is a critical component in constructing new-type power systems, with its level of intelligence directly impacting the reliability. Telecommunication for utilities has a long history in the transmission level of the power supply system and Siemens was one of the first suppliers of communication systems for power utilities. Since the early 1930s Siemens has delivered power line carrier equipment for high-voltage systems.
