    Default SBC Codes

    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.

    Thanks.

    Hey!!!

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

    SBC FIBER OPTIC CABLE CODE CONVERSION CHART



    Fiber and Cable Description Number of Fibers

    ___ ___ ___ ___ ___ ___ - ___ ___ ___

    S1 S2 S3 S4 S5 S6 S7

    S1 Fiber Type
    3 - Single Mode Fiber Dual Wavelength 1310/1550nm

    S2 Transmission Performance
    4 - .4db is the standard for all outside plant applications

    5 - .5db is used for short applications, i.e. central office and customer premise applications.

    S3 Sheath Description
    I - Dielectric – Primary use all underground and aerial applications

    9 - Dielectric – applied to ribbon design

    W - Single Armor – Provides locating armor

    Q - Single Armor – applies to ribbon design

    V - Double Armor - Rodent resistant

    N - Single Armor Stat Track

    6 - Riser central office

    4 - Riser Indoor/Outdoor

    7 - Plenum

    P - Petroleum Resistant

    U - Steam Resistant

    X - Pending Future Code

    S4 Tensile Loading
    2 - 600lb. tensile rating is applied to all approved designs

    I - Intrabuilding OFNR riser cable

    M - Figure 8 aerial self-support cable

    S5 Cable Unit Type/Central Member
    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

    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
