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.

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.![]()

L - Loose tube design is an individual stranded fiber design in buffer tubes in groups of 12 typically used in 48 fiber counts or less.
M - Ribbon matrix is a 12-fiber ribbon design used in higher count cables from 73 to 360 and is intended to be spliced using the mass fusion splicing technique.
S6 Fibers Per Unit
T - All approved design use 12 fibers per unit
S7 Fiber Count
006-360 - Number of fibers in cable
Example: 6,12,18,24,36,48,2,96,120,144,216,288,360
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
You forgot to include using a modified C clamp![]()
