[comp.dcom.telecom] Call Quality to and From Japan

Here is a brief summary of my experiences line quality to/from Japan.
When I was in Japan this past year calls placed through ITJ (0041)
were crystal clear with very little delay (obviously fiber optic).
Calls placed through KDD (001) had the characteristic "satellite
bounce" delay along with a much lower signal/noise ratio (ie it was
noisy).  I'm told that (0061)'s line quality is also good, but rarely
used it.

As far as calling TO Japan goes, I tried to transfer a file via modem
over normal Sprint lines over a year ago and was unable to.  The line
was simple too noisy.  However, I tried it again this week (Sprint
again), and had no problem at all.

Does anyone know which long distance calling companies offer fiber
optic lines to Japan from the U.S.?  When I've asked Sprint operators,
I've received a number of different answers.  "No, sir.  There is no
such thing as a fiber optic line to Japan".  "Yes, sir.  100 % of our
lines are fiber optic", etc etc.
