MSS Fibre 4F LOOSE TUBE CABLE OM3 PEnYLON CAB-LT-04-MM3

Description

MSS 4F OM3 Loose Tube Fibre Cable for Underground Installations

The MSS Fibre 4F OM3 Loose Tube Cable is designed for multimode fibre optic installations requiring a robust cable construction for underground and external network infrastructure. Identified by product code CAB-LT-04-MM3, this four-core cable combines loose tube fibre protection with water-blocking materials and a durable outer jacket for demanding installation environments.

The loose tube construction houses the optical fibres in gel-filled tubes, helping protect them from moisture. A dry-block core incorporates water-swellable materials to provide an additional barrier against water ingress. This combination makes the cable suitable for consideration in direct burial and conduit or duct applications, subject to site conditions and installation requirements.

Water Blocking and Non-Metallic Strength

The cable incorporates a non-metallic, fibre-reinforced plastic central strength member to provide tensile strength without a metallic reinforcing component. This construction can be beneficial in fibre infrastructure projects where a non-metallic cable design is specified.

Thixotropic gel-filled tubes help prevent water from entering the fibre tubes, while water-blocking tape and swellable yarns provide additional core protection. Together, these features support the cable’s intended use in external installations where moisture management is an important design consideration.

UV and Termite-Resistant Outer Construction

The MSS 4F OM3 cable features a black, UV-resistant polyethylene (PE) inner sheath beneath a blue polyamide nylon outer jacket. The nylon jacket is designed to resist UV exposure and insect or termite attack, making it suitable for projects requiring additional protection against environmental and biological exposure.

The cable is non-armoured and does not include a sacrificial sheath. Installers should assess the route, ground conditions, mechanical protection requirements and applicable project specifications before installation. For electrical contractors and network specialists, this cable offers a practical combination of multimode fibre capacity, water-blocking construction and a protective external jacket.
