Claim 0:
1. A method for simultaneous transmission of upstream and downstream signals in a same frequency band, the method comprising:
receiving at a position following an FDX node in the downstream direction, a downstream analog signal from the FDX node and an upstream analog signal in the same frequency band;
separating the downstream analog signal and the upstream signal into a first path and a second path, and amplifying each of the upstream signal in the first path and the downstream signal in the second path;
reducing crosstalk between the upstream and downstream signals so as to isolate the separated downstream analog signal and the separated upstream analog signal from one another;
sending, the amplified downstream analog signal downstream; and
sending the amplified upstream analog signal towards a full duplex node.
