Totally missed that last part XD
There are two kinds of countries: those that use the metric system and
those that have been the moon.

I also use EXFOs and they will read to the meter, but if you have a fiber cut
out 25 miles, I will bet good money that when you dig up the spot where your
OTDR says the fault is, you will be off by 100 feet or more if you did not do a
test from the nearest splice point. In reality it will be of
Are people saying you could check where the OTDR says the splice is, and then
knowing where the splice is, use that to correct the distance to the cut?
Kind of like the way RTK increases the precision of GPS location by using known
reference points?

That hasn't been my experience, but at the same time we're not 25 mile
shots - it's maybe 15 max.

So on a 15 mile shot with a problem somewhere in the middle, you think you can
wheel it off and dig it up and find it?
One shot, from the end. Walk right to the problem?

Shouldn't you be able to look at the distance to fault from the last
splice, look up the cable footage marker going into that splice closure (go
check it if you didn't document that when it was built), check footage
marker at closest handhole, and then wheel it off from there?

Don't forget to adjust for cable helix factor either.

When you are out in the desert tracking direct bury fiber, only handholes are
splice points good luck.
If the closest hand hole is 2 miles away from the area of the fault, good luck.
You will wheel it off, read the sequential, then wheel it off again, dig
again. Not find the damage. Then
What's caused the damage in your experiences? Random failures or big
yellow cats?

Our damage has been almost exclusive gopher damage.
They eat direct bury and microduct.
They will eat .75” duct too but not as much. Rarely do they eat through 1.25
HDPE.
This is learned from doing all the wrong things over the past 25 years.

Yeah, with direct bury and no handhole for miles, you are in a tough spot.
If the footage marker on the cable you dig up is still there, you could go
off that instead of guessing or cutting.

Good point, with direct bury the sequentials are frequently rubbed off.

That is one of the main reasons the national carriers standardized on 3"
duct because anything bigger than 2" is less likely to be eaten.
Burrowing animal damage was more common when most fiber was long
distance transport use. In urban areas it tends to be yellow cats and
pole sprouts.

I have only found one 1.25” duct (1.66” OD) ever that was eaten through. So it
is rare. Lots of .75” and lots of microduct has been eaten up.
