Optical riser cable KC-OKE

The KC-OKE cable is intended for installation inside buildings (including vertical), in cable trays, in cable ducts.
Structure
  1. Optical fiber;
  2. Strength element (FRP fiberglass rod);
  3. Micromodule;
  4. PVC outer sheath. In the “nf” version outer polyethylene sheath is made of flame-retardant low-smoke halogen-free compound.

    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).
  5. Cable termination section.
