The document discusses how optical Ethernet can help telecommunications networks meet increasing bandwidth demands from new services like HD video. It describes how optical Ethernet provides gigabit capacity to multiple homes using fiber to the home infrastructure. It also summarizes how networks can smoothly migrate to optical Ethernet by upgrading existing DSL networks or migrating leased line services.
