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 corrosion and moisture.

Ordering Information
UCFIBRE™® LTFMSMNWM SERIES FO Cable part numbers are made up using the table below. The part number always starts with the letters LTFMSMNWM to denote that it is a UCFIBRE™® LTFMSMNWM SERIES FO Cable. This is followed by 3 numbers which symbolizes the core quantity and then 2 letters to denote the fibre type. Example of a UCFIBRE™® LTFMSMNWM SERIES FO Cable part number: LTFMSMNWM08M1 The above example describes an OM1 (62.5um, Orange Sheath) UCFIBRE™® LTFMSMNWM SERIES FO Cable, with 8 cores.
