Re: A wire is a wire is a wire
Bonjour Old Computer,
I wish Bell (our phone company like France Telecom
is yours) were offering such quality DSL filters!:
%20.PNG)
High Quality European ADSL Low-Pass Filter (60 dB rejection @ 40 KHz)
Hummm... But i guess FT doesn't carry it neither;
you had to build it yourself, as i recall! Right?

| Hi Bicephale
Sorry to disappoint you, but the filter is not mine. 
I don't have enough good equipment to achieve so good results, and maybe not the intellectual capacities.. lol
You need at least a spectrum analyser, oscilloscope (I have one) and a good BF / HF generator. (And all characteristics of the tores used for).
I got it 1 year ago. It is from Alcatel but not sold public. Was installed by FT some years ago on request.
A nice one is the LEA Filter PCE2B0P-20, but I never could get the diagram.

You can grab the specs in .pdf format.

At least, some effort is being made to characterize the Lea filters...
My only disapointment is that it may be pointless to ask Bell for this!

1 edit | I already opened the Alcatel filter.
BTW you can't see the cores or capacitors. The box is filled with a sort of hf brown glue.
Edit : How it looks .. and if you want to buy one ...

| I got this about Specs of LEA filters:
Have a look on the attachment.
With one standardized pinning it is possible to place xDSL filters like the ITU-T
G992.1 Annex A (POTS +E1) 600 Ohm and ETSI ATA TS 101 952 -1-1 option
(A) and ETSI ATA TS 101 952 -1-1 option (B) on one PCB layout. |
