Interesting. Have never heard of that. Are there dangers of the plastic
cracking etc?
Can you do it with dry ice? Much easier to get.

You can also cold clamp the fiber cable with liquid nitrogen to induce a
temperature dependent loss event to pin point your location. No cable cutting
needed.

Can you improve the accuracy by testing from both ends?

Still, length is not an exact science with OTDRs. Especially if it is a long
shot.
Every fiber has a different index of refraction and velocity factor. And these
characteristics vary along the entire length of the fiber.
Then there is twist in the tube, wavering routes and slack loops etc. And
there is also timebase accuracy, which varies with temperature...
So if you have gopher damage in the desert and the closest hand hole is 10
miles away, you will have to dig and cut several times before you zero in on
it.

We had a $300 OTDR. The only thing it didn’t do was estimate length very well
if it worked at all.
My friend asked how much money we’d save if we dug up the wrong lady’s yard to
replace a fiber that wasn’t broken.
Then we bought a Viavi, waited for a show discount. Now we can dig up the right
lady’s lawn.

I thought the same thing. I had to cancel their service after just a week
or two because streaming was absolutely a joke (looked to me like their peering
was full, couldn't get any kind of capacity beyond their network). They left
this convenient wall plate with an APC bulkhead just sitting here...

I have always wanted to connect a source of upstream light to my

to troubleshoot. Especially if I made it randomly intermittent and on a timer.
Perhaps during the first minute of the superbowl or something...?

I know Exfo has units with an optional PON port for connecting to a live
on-net fiber and testing. Maybe this is more or less standard anymore, my
current OTDR is a bit dated.

If it’s anything past that, the splicers with the fancier/costlier OTDRs get
involved. Price point is right and it does what they need it to do.

assume they've come a little ways since then. I don't need anything for super
long distances, mainly just access, PON features are a plus. --
