2-24 Cores, Indoor Tight Buffer Distribution Cable, LSZH Sheath


One of the most widely used UCFIBRE™ Indoor cable, MT series is excellent for indoor installation that provides a safe setup against flame propagation and its flexible yet robust construction makes installation at ease.

Additional Options

  • PVC Sheath for indoor applications
  • PE Sheath for outdoor applications
  • Steel Wire Braiding for armouring protection


  • Tight buffer: Each fibre is coated to 0.9mm with LSZH
  • Strength Member : Aramid yarn
  • Outer Sheath:LSZH compliant to IEC 61034,IEC 60754-1&2,IEC 60332-1 & IEC 60332-3-24
  • Suitable for indoor installation requiring flame retardant, low smoke and halogen free environment

Ordering Information
UCFIBRE™ MT SERIES FO Cable part numbers are made up using the table below. The part number always starts with the letters MT to denote that it is an UCFIBRE™ MT SERIES FO cable. This is followed by 3 numbers which symbolizes the core quantity and then 2 letters yo denote the fibre type. Example of a UCFIBRE™ MT SERIES FO Cable part number: MT008M1 The above example describes an OM1(62.5Sum, Orange Sheath) UCFIBRE™ MT SERIES FO Cable, with 8 cores.
