||In order to solve the fiber to home last mile problem, is the integration of optical (e.g., GPON) and VDSL2 architecture, is currently FTTdp(Fiber to the Distribution Point), combining fiber and copper network architecture and then take advantage of the old line infrastructure. However, the central office equipment power source installation is problem that in order to solve it, the power source be use the copper twisted pair to transmit the power from user’s home to the central office equipment.|
The remote power feeding using PoE(Power over Ethernet) technology, the central office equipment required power consumption of 10 watt or less, to provide a 200 meter length of twist pair copper wire(26AWG), to meet the small communities or building demand. However, the outer suburbs could clearly insufficient and can only be used for a single port.
Further development a new circuit PoD(Power over xDSL) that basic theory and architecture base on PoE. The PoD can provide the 30watt of power consumption for 8 port central office equipment, the length can up to 300 meter. The PoD will improve the range of service、reduce the number of equipment installed、the basic expense and the equipment maintenance trouble.
Expect to provide easy set up、expand the scope of services、installation and maintenance costs low for FTTdp network architecture.
