OKL-8 fiber optic cable figure 8 with dielectric remote load-bearing element
OKL-8 fiber optic cable like figure 8
Application:
Cable type is designed for application and operation on overhead utility and power lines under the impact of strong winds and ice-loading or their combinations.
Cable design:
1. Optical fibers acc. ITU-T G.652 D / G.657A1.
2. Loose Tubes – PBT (polybutylene terephthalate).
3. Core filling – thixotropic gel.
4. Fastening winding of threads and tapes.
5. Central strength member (fiber reinforced plastic).
6. Fillers (if applicable).
7. Strength layer - aramid yarns.
8. Strength messenger - fiber reinforced plastic or steel rope.
9. Outer sheath – polyethylene (HDPE).
Design versions:
1. Multimode Fibers acc. ITU-T G.651.1; IEC 60793-2-10.
2. Outer sheath :
- low smoking;
- halogen-free;
- flame retardant compound (LSZH).
