Sorry, I don't understand Japanese :(

Could be. Tests are needed.

The shorter the path, the better. So if LC filter is inside FST-01 it's
better. But you have to put a cap on your attacker's resources. So, in
the end, it all depends on your profile: is it "worth" putting so many
resources to read your mails? And is the rest of your equipement TEMPEST
safe, too? I remember a project that used a CRT monitor as FM
transmitter that could be received by any FM radio, and another that
could (more or less) "receive" your screen from some meters away.

I fear that magjack is (C) Apple, but there are probably other
alternatives around. One could be ZNAPS:

Or just have a look at google results for "usb magnetic connector".
