DConnect’s optic fibre cable features a loose central tube design with a single-mode G.625D fibres. The fibres are protected by a mica fibre barrier, corrugated steel tape armour, and a halogen-free, flame-retardant LSZH-UV outer sheath.
Since mica is non-combustible and thermally stable up to 1000°C, it forms a heat barrier that prevents fire from damaging the optical fibres. The construction also includes water-blocking elements and glass yarn strength members to provide high durability in harsh environments.
As a fire-resistant fibre optic cable with a central loose tube supplier in the UAE, this cable serves as an essential component in critical communication infrastructure that needs reliability in extreme conditions, like fire.
Features
- Fire resistance: Maintains circuit integrity during fire to keep emergency systems running.
- Mica tape insulation: With a high thermal stability, it forms a heat barrier that protects optical fibres.
- Central loose tube design: Gel-filled tube shields fibres from bending, pulling, and crushing stresses.
- Metallic armour: Corrugated steel tape safeguards the core from impact, compression, and rodent attacks.
- LSZH-UV outer sheath: Halogen-free, flame-retardant jacket reduces toxic smoke and resists UV degradation.
- Compliance assured: Certified to ISO 9001 and IEC 60331-25 for quality and fire performance.
- High-reliability fibres: Manufactured using pure silica and germanium-doped silica fibres with UV-curable acrylate primary coating.
