Features:
- fully dielectric
- resistant to electromagnetic interferences
- resistant to longitudinal water penetration
- can be installed in the proximity to electric installation
- easy to install
Applications:
Cables are designated for transmission of digital and analogue signals within the whole optical bandwidth.
They are prepared for making fast connection between optoelectronics devices, laying in cable ducts, use in places with high risk of rodents attack.
Cable construction:
1. Optical fibres
2. Loose tube
3. Central element non-metallic
4. Dry seal
5. Reinforcement
6. Outer sheath
7. Rip-cord
