Optical cable with central tube without armor KC-OKGO

The KС-OKGO cable is intended for external installation, on walls of buildings, on a carrying cable. Laying in cable ducts and blowing into protective polyethylene pipes for short distances are possible.

If the cable has a fire-resisting sheath, it can be installed both indoors and outdoors, and “nf” is added to the cable marking.

Structure
  1. Optical fiber;
  2. Intramodule compound (thixotropic gel);
  3. Optical loose tube (PBT – polybutylene terephthalate);
  4. Peripheral strength element (FRP fiberglass rod);
  5. Outer light-stabilized polyethylene sheath. In the “nf” version the outer sheath is made of a polymer that does not propagate burning when laid single.

    For cables in the “nf” version, which are flame-retardant when installed in bunches, the category of flame retardation is indicated in brackets: nf(A), nf(B), nf(C), nf(D).

    Types of the sheath according to fire hazard indicators are defined by the following indices in the identification markings:
    LS (Low Smoke) – reduced smoke emission;
    FR (Fire Resistant) – fire resistance;
    ZH (Zero Halogenic) – no halogen emission during combustion;
    HF – no emission of corrosive gaseous products during combustion and smoldering;
    LT – low toxicity of combustion products.
