MSS Fibre 12F LOOSE TUBE CABLE OM3 PEnYLON CAB-LT-12-MM3

Description

Reliable Fibre Protection for Underground Installations

The MSS Fibre CAB-LT-12-MM3 is a 12-fibre OM3 multimode loose tube cable designed for external fibre optic installations. Featuring a protective dual-sheath construction and water-blocking components, it provides a practical solution for telecommunications infrastructure and network installations requiring underground cable routing.

The cable incorporates a black polyethylene (PE) inner sheath and a blue polyamide nylon outer jacket. The PE sheath provides UV resistance, while the nylon jacket offers additional resistance to UV exposure and insect or termite attack. This construction makes the cable suitable for specified outdoor applications where environmental protection is an important consideration.

Water-Blocking Loose Tube Construction

The cable uses gel-filled loose tubes to house and protect the optical fibres. Thixotropic gel helps prevent water ingress into the tubes, while water-blocking tape and swellable yarns provide additional protection throughout the cable core. This combination supports its use in underground installations where moisture management is essential.

A non-metallic, fibre-reinforced plastic (FRP) central strength member provides tensile strength without introducing a metallic central reinforcement component. Polyester-based rip cords also assist with sheath removal during cable preparation, helping installers access the internal construction for termination and installation work.

Versatile Outdoor Fibre Network Applications

Designed for direct burial and conduit or duct installations, the CAB-LT-12-MM3 supports a range of external fibre network projects. Its 12-fibre OM3 multimode configuration is suited to compatible optical networking systems, subject to the requirements of the equipment and installation design.

For electrical contractors, telecommunications installers and infrastructure teams, this cable combines a practical loose tube design with protective sheath materials and integrated water-blocking features. Its non-armoured construction is worth considering when selecting the appropriate cable protection for the installation environment.
