IKB...M Multitube optical fibre cable for buried installation


INTEGRA optical fibre cables are designed for installation in different invironments of telecommunicational networks. Range of application: in the ground, rivers crossings, in bogs to the depth of 2 meters, in ducts, over the bridges and overpasses, in tunnels, in sewer ducts, inside buildings. 

Special characteristics of optical fibre cables:

Fire-resistant — IKBN… (for installation in tunnels, sewer ducts, inside buildings);

Improved moisture protection (with plastic-coated aluminium tape) — IKBZ… .

Double armour-coating of steel wires  — IKB2…– M…This construction can be installed in the grounds of all categories (when low-temperature deformations are possible).

IK– INTEGRA-CABLE optical fibre cable
B – armoured (stranded steel wires)
М – multitube construction
6 – number of tubes stranded around the central strength memeber
P – central strength member type (fiberglass rod)
Н – optical fibre type (single-mode, ITU-T G.655)
36 – number of optical fibres in the cable
8.0 – maximum tension allowed, kN

  • There is a possibility to increase the numder of fibres in the cable by implementing a multi-stranded loose tube construction
  • The operating temperature range can be extended from –60°С to +70°С.
