UCFIBRE™® LTFIM SERIES

2-144 Cores, LTFIM Series Fire Resistant Non-Metallic LSZH Cable

Features

  • Central strength member: FRP with PE 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
  • Longitudinal Water Tightness:water-blocking tape & yarns (dry core) and fire resistant layer
  • Outer Sheath: LSZH. Flame Retardant to IEC 60332-3C
  • Suitable installation is indoor and indoor/outdoor in and between public buildings, in tunnels, metro lines and other places where need very high degree of fire safety and support for critical communication, UV resistant.

Ordering Information
UCFIBRE™® LTFIM SERIES FO Cable part numbers are made up using the table below.The part number always starts with the letters LTFIM to denote that it is a UCFIBRE LTFIM 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 UCFIBRE LTFIM SERIES FO Cable part number: LTFIM040M2 The above example describes an OM2 (50um, Orange Sheath) UCFIBRE LTFIM SERIES FO Cable, with 40 cores.
