John -
It has been known for some time that when optical fiber is
bent, it leaks a little. In the OCT2002 issue of Test &
Measurement World, a "live fiber detector" is discussed as a
part of a test setup:

I had forgotten the terminology, and what Mr. Tarver related about the
classes is true, but it is not true that electric or magnetic fields should
theoretically be able to interact with a stream of photons.

You're partially correct, Ken. However, the photon (in
quantum mechanics) is the particle that mediates the
electromagnetic force; photon also the name given to the
particle that is a quantum of electromagnetic energy. Thus,
photons are involved as the particle analog to an
electromagnetic wave.

Chris,
some excellent points! My take on this is that a fiber optical cable has a
cutoff frequency that is way above the "RF" frequencies we are concerned
with. It just won't act as a waveguide

example, you can use either an electric or magnetic field to deflect and
point an electron beam, but you cannot do so with a beam of light.

Hi,
I'm wondering how to handle fiber optic cables under the new EN55022
going into effect August 2003. Measurements are supposed to be made
on telecommunications cables, and fiber optic cables are being used
for telecommunications. From my reading of the standard I don't see
