    I don't know if all fiber codes are the same but here is the AT/T codes.

    SOCC Character S3: Sheath Description
    The third character S3 describes the sheath construction from the inside to the outside of the cable. The sheath description originates outside the cable core and it’s associated core wraps and binders. Included in the sheath description are the shield and/or armor for mechanical and electrical protection. The possible elements in the sheath are corrugated steel S, corrugated copper C, corrugated stainless steel SS, steel wire SW, metallic rod MR, dielectric strength members D, dielectric rod strength members DR, and polyethylene P.

    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.
