Description
This Draka OM4 multimode fibre optic cable is designed for internal and external network installations, including LAN and WAN backbones, fibre-to-the-building (FTTB) connections, telecom access networks and business connectivity projects.
The cable features a stranded loose tube construction with gel-filled tubes containing up to 24 fibres per tube, providing protection against moisture ingress while supporting high-density fibre deployments. Its universal design makes it suitable for installation in ducts, cable trays and external network routes.
A UV-stabilised FireBur LSZH (Low Smoke Zero Halogen) outer sheath provides resistance to environmental exposure while meeting stringent fire performance requirements. The cable is CPR rated B2ca-s1a,d1,a1, making it suitable for installations where enhanced fire safety compliance is required.
E-Glass strength elements provide additional mechanical protection and a degree of rodent resistance for outdoor and underground applications.
