Abstract
We developed an IP network system for power line customers to operate in the year 2000. ac米兰中国官网 objects of developing this IP system are an amazing system price reduction compared to the growingly popular 1:1 transmission system, and also a variety of applications for individual customers with customer security assurance.
ac米兰中国官网 scheme of this optical system adopts branches of the 8x4 passive double star optical system. To develop speed and cost efficiency, we selected a mass produced cable modem, which accepts IP and ATM controlling protocols that can be used for PDS optical networks.
Another important aim is to assure a channel capacity with high Quality of Service (QoS) to transport customer data with sufficient reliability.
Since this system started operation customer numbers have gradually increased, ac米兰中国官网 system has demonstrated its design efficiency and cost performance. The skeleton ac米兰中国官网 structure of the system ac米兰中国官网 equipment are described below.
