Flexible optical cable with suspended strength element KC-FTTHSC

The KС-FTTHSC cable with G.657A2 fiber is intended for overhead installation on the supports and along the walls of buildings. It is recommended for use in tap-offs from the post to the house, both for laying indoors (without a suspended element), and in outdoor conditions.
Structure
  1. Flexible optical fiber;
  2. Strength element (FRP-A aramid rod or FRP-E glass rod or galvanized steel wire);
  3. Outer LSZH sheath;
  4. Suspended strength element (steel wire or fiberglass rod).

Optical fiber standard
Number of optical fibers in cable
No designation – the central strength element is made of galvanized steel wire.
П – the central strength element is made of fiberglass rod
А – the central strength element is made of aramid rod
No designation – polyethylene sheath.
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.
