Isolating homeplug networks

["Don Croata" <el.croata@xxxxxxxxx>]

Hi,

I'm a novice and been searching for articles in this group for ways to
isolate a homeplug network for external interference (other networks,
harmonics, etc.) coming from other appartments, so my internal network
becomes clean and I could use several OvisLink HP-1000U in my house at
full bandwidth possible (with 10mbps I'm OK).

I'm planning to put a low-pass filter (think anything under 100Khz
should work since I want to attenuate 1Mhz freqs and superiors) just
BEFORE the power distribution box. A filter like a butterworth pi (2
capacitors in parallel with 1 or 2 series inductors in between) should
work...

I've seen commercial ones very expensives -for what they do- (US$ 60)
at Leviton's, and they only bear 20 A!!! They'd die at the first short
circuit... maybe leaving the inductors in open-circuit (!)

My questions are:

1) Does exists a non-intrusive low-pass filter? I mean one that doesn't
need to open wires, just put it around the line

2) Is possible to build or buy one who bears more decent amps in case
of a short circuit?

3) I don't know the right name for these... How should I search for
that type of items in the web? low pass filter gives me very ambiguous
result...


Many thanx,
Cro
