It is also in some ATT, Centurylink, VZ, other LEC specifications and
requirements for installation in their facilities. Especially for power
cables. They probably have kept the standard and not allowed newer
labels mainly because you can still read them even when you get large
stacks of bundled cables. Also they are not likely to get pulled off.

aren't really important anymore. They're just still in various
companies' cabling specs so we keep using them.
I wonder what they used before that made "non-conductive" a noteworthy
feature of the 145P. Steel dog tags? Wet paper? Cuneiform on clay
tablets?

I have been in the industry since 1978 and they way predate me. The
ones that I used were made out of a compressed fish paper which is
highly fire resistant. Frequently connected with a brass ring to
whatever it is they were marking.
They came in a kit with ink and a stencil to hand lettering the tags.
Kinda like leroy lettering. Very durable.

How long have telcos been using these 145P tags, and what's the origin
story?
I see them called out in some specs. The manufacturers' pitch is that
it's "non-metal" and "fiber-based" to make it safe around electrical
installations.
I see the installers are tying the 145P on things and then printing
out a label on their label printer to stick onto the 145P tag. If the
printed label is acceptably "non-metal" and safe around electrical
equipment, then why did you need the 145P tag? Why not just print out
a wire marker label?
I'm speculating that these come from a time when you couldn't just
print out a plastic label on demand, and you could tie this onto the
cable and write on it with a marker, but I have no basis for that
other than they don't seem to make sense any other way.
