This loose tube dielectric optical cable is designed for external underground installations in ducts by pulling, jetting or floating techniques or by underground usage as per Australian standards. Mainly used for distribution and access network. Polyamide provides anti-termite protection.
Made up of a loose tube construction, the tube is made of a thermoplastic material, containing up to 24 optical fibers filled with a low viscosity, thixotropic, non-melting gel fully compatible with fiber coating and tube material, a glass fiber reinforced plastic material (GRP) strength member and water swellable elements (dry-core) providing longitudinal water tightness. The sheath is made up of a UV stabilized polyethylene in compliance with AS 1049. Two ripcords provided beneath the sheath for easy removal. The outer jacket is a UV stabilized polyamide (Nylon) in compliance with AS 1049 integrally bonded to PE sheath.
Available only in Australia.
