Loose Tube Fibre Optic Cables
Loose Tube Dry Core fibre should be used when the required cable is either direct buried or installed within underground conduit. This type of fibre is designed to withstand most outdoor conditions including moisture ingress, thermal shock, lightning, wind abrasion, and ice loading. Loose Tube fibre has a ruggedised external PE jacket.
At our 4Cabling termination facility, we can manufacture pre-terminated cable to your specifications including length and connector type. Our Loose Tube Dry Core Fibre Optic Cables are fully tested and ready to be installed. They can be supplied on cable drums ready to ship out to your installation.
