MSS Fibre 12F FIRE RATED MONO TUBE CABLE OM3 CAB-MT-12-MM3FR

Description

MSS Fibre 12F Fire-Rated OM3 Mono Tube Cable

The MSS Fibre CAB-MT-12-MM3FR is a 12-fibre OM3 fire-rated mono tube cable designed for fibre optic installations where circuit integrity during fire exposure is an important consideration. Its construction combines heat-resistant materials and a low smoke zero halogen (LSZH) outer jacket to support demanding indoor applications.

Designed for fire-resistant installations, this cable meets the stated IEC 60331-25 performance requirement of up to 120 minutes at 750°C, with a maximum increase in attenuation of 0.5dB. This makes it a suitable option for specified installations involving fire alarm systems and other applications requiring fire-resistant fibre cabling.

The cable’s OM3 multimode fibre specification supports compatible optical communication systems. With 12 fibres contained within a mono tube design, it provides a practical solution for installations requiring multiple fibre connections within a single cable.

Heat-Resistant Construction and LSZH Protection

The CAB-MT-12-MM3FR incorporates mica tape to provide heat-resistant protection around the cable’s internal construction. Aramid glass yarns contribute strength and protection, helping the cable withstand the demands of installation and service.

Its jelly-filled mono tube construction provides an additional design feature for the fibre assembly. The red LSZH outer jacket is specified as UV-resistant and offers a low-smoke, zero-halogen material choice for suitable indoor installations.

These combined construction features make the cable relevant to projects where fire performance, cable identification and material selection are important considerations. Installers should confirm the required cable rating and installation conditions against the project specification before use.

Suitable for Fire-Resistant Fibre Installations

For electrical contractors, communications installers and project procurement teams, selecting the correct fire-rated fibre cable helps ensure the cabling specification aligns with the requirements of the installation. The MSS Fibre 12F OM3 mono tube cable is intended for applications requiring its stated fire-resistance performance and multimode fibre configuration.

Its 12-fibre design can support installations requiring several optical pathways in one cable, while the red jacket helps distinguish it from other cabling within an installation. Verify compatibility with the optical equipment, termination components and applicable fire-system requirements before ordering.
