RE: [EFM] Active Architectures

> I think the architecture you describe merits further consideration.  

Not only does it need further consideration, but it also should serve as
a benchmark against other pure PON approaches from a cost/benefit
perspective.  Perhaps the Half-PON approach could also be equipped with
both Cat3, Cat5 and Fibre interfaces, so we have a half-PON beast with
short reach (100TX) and long reach copper (EFM) legs as well.  This
would make the device suitable for use both in a MDU and in the OSP.   I
would even say that rather than having a 16:1 split ratio, a 10:1 would
be even more appropriate as it would make the upstream entirely
non-blocking for that node, thus making this even more friendly to open
access considerations.
