UCFIBRE™® LTFMSMWM Series

2 ~ 96 Fibres, SWA, Heavy Armoured Cable, LSZH Sheath

Overview

This cable is especially designed for harsh environments. The double armour combination of corrugated steel tape and galvanized steel provide superior crush protection to the fibers. Water tightness compound within loose tube reinforced by polyster tape and jelly protects the fibers against chemical, corrosion and moisture.

Additional Options

  • IEC 60332-1, IEC 60332-24, IEC 61034-2, IEC 60754-1/2

Features

  • Central strength member (CSM): glass fibre reinforced plastic material (FRP) with plastic coating when needed.
  • Tube:thermoplastic material, containing up to 12 optical fibres and filled with a suitable water tightness compound.
  • Stranding: The required numbers of elements (tubes or fillers) are SZ stranded around the central strength member.
  • Core Wrapping: polyester tape (jelly filled)
  • Inner Sheath: LSZH
  • Inner Armour: Corrugated steel tape
  • Middle Sheath:LSZH
  • Outer Armour: Galvanized steel wire. WB jelly filled, wrapped with cotton tape
  • Outer Sheath: LSZH
  • Suitable for Direct Buried, Rodent/Termite/Water/Chemical environment.Flame retardant to IEC 60332-3C. LSZH to IEC 61034 & IEC 60754-1&2.

Ordering Information
UCFIBREâ„¢ LTFMSMWM SERIES FO Cable part numbers are made up using the table below.The part number always starts with the letters LTFMSMWM to denote that it is a UCFIBREâ„¢ LTFMSMWM SERIES FO Cable. This is followed by 3 numbers which symbolises the core quantity and then 2 letters to denote the fibre type.Example of a UCFIBREâ„¢ LTFMSMWM SERIES FO Cable part number: LTFMSMWM08M1The above example describes an OM1 (62.5um, Orange Sheath) UCFIBREâ„¢ LTFMSMWM SERIES FO Cable, with 8 cores.
