SBC Codes

[Goldenboy]

Anyone got a copy of the fiber codes to post? I think I got me a sheathless fiber here but can't remember the codes.

Thanks.

I don't have it handy right now but if the 3rd digit is a 1 or 9, that means it's dielectric. No way to locate it unless there's a tracer wire / something else / a fishtape available to hook up to along the same path.

I tried googling "siecor fiber construction codes" but couldn't find the PDF online. It's out there somewhere, I have a hard copy of it but my training manuals are at home gathering dust right now.

Thanks alot WB. I knew someone here would have the codes. I don't know how I forgot but oh well now I know.

BTW it did have a sheath just didn't like to tone.

I tried to find the codes on the 'net but couldn't find anything close. I found the att trouble codes if that means anything.:p

Hey!!!

I wear that code on my side in a sheath...

Thank you Hurricane.

A Dielectric Fiber is one that does not have a sheath. Therefore to locate it you need tracer wire. To determine whether a particular fiber has a sheath or not look at the 3rd position in the 6 digit fiber ID code in the AT&T prints. If the 3rd letter is an I (as in indian) or 9 then it is dielectric and does not have a sheath. For example:

3492MT - 144 = 144 strand fiber with no sheath (dielectric)

5BQ2MT - 072 = 72 strand fiber with a sheath

Basic Troubleshooting Steps

Fiber-Dielectric/Sheathless and Fiber Drops

Troubleshooting Fiber Optics Problems

* Verify from Prints / Records – Cable size, sheath, date installed, hook-up points
* Don’t trust the print, verify by carefully inspecting coding on the cable
* Hook to tracer wire, if available
* Fiber Drop – hook to thin copper wire on cable coating
* Use a magnet to check for sheath presence
* Couple instead of direct connecting
* Run a fish tape through conduit containing sheathless fiber
* Call facility engineer and verify if buried with a copper cable
* Initiate a request to have customer install a tracer wire if one does not exist
