Evolution-friendly upgrade of CATV networks towards a broadband full services access network

Summary form only given. To summarize, the described WDM-APON (WDM ATM-PON) technique which multiplexes four standard 622/155 Mbit/s APON systems over an amplified 1:64 split ODN, with approximately 40 customer premises connected to one ONU, enables a maximum available capacity per IUP of400 kbit/s downstream and 100 kbit/s upstream and peak rates of 32 Mbit/s downstream and 8 Mbit/s upstream. The total number of customers that can be connected to this system is approximately 2400. The AM-CATV service can be delivered to all customers connected.
