| | I've never seen this before! This is a SuperiorEssex Indoor/Outdoor tight buffered fiber. The fiber has a crystaline substance which has formed around the jacketing of the cable and the buffered fibers. This is installed in a high school just outside of New Orleans. Any suggestins on what may have caused this? Anyone ever seen this before?

| Michael,
Yes, that sure looks like it. I believe this crystal action happens when moisture/water vapor interact with the cable properties chemicals and/or minerals.
Maybe the fiber wasn't cleaned and capped off properly. BTW, what connectors are those.
The best person to answer this might be the Team Lead SME for OSP.
Terry, can you help out with this one?

| It has been suggested that pulling lube might be the culprit!
Just a little more about the installation you might find interesting.
There are two fiber boxes in electrical closets, one in a ceiling, and one in a data closet. The one in the data closet is not affected, most likely because it is in a climate controlled room. The contractor working on this issue is not the contractor that installed the fiber, so I can't determine what type of pulling lube was used!
Maybe the high school science teacher can help!

Kevin, I think they are Corning Unicam's. The contractor troubleshooting this job sent the pictures to me!

Well if I were to guess, I would say...
The second and third photos are the same box and the fourth is the one in the ceiling. Did they send you a shot of the Data Room? Wish these were something other then cell phone shots, but we'll work with that. 
I doubt Polywater was used, though seen this before. Could.....could, be something else.

| Kevin,
Thanks for the heads up on this one!
I sent this to Tim West in Applications Engineering to see what he thinks! Back in a few!!tb |

| | Actually we're already on this. We have samples of the unknown material at various labs for analysis and are working with the contractor to get the actual cable removed for analysis. The best theory at this point, as some previous posters have mentioned, is some sort of reaction between the various materials involved. As soon as we determine what all added up to create this, I'll follow up with this forum. |

| | I can't imagine that cable lube would be the cause. Especially on the bufferered fiber (How could that much cable lube be on the fibers after the jacket has been removed?). It looks like an older installation. As such - I think that the problem would have surfaced some time ago. My vote is for vandalism. If it does turn out to be cable lube - I'd say "Shame on the installers". If it needs that much lube - it needs a bigger pipe or more pull points! Please post the findings here. |

| Here's my question.
What did they use to clean off the fiber? That's where I'm leaning. 
Hope to find out soon.
