Application
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 . The nylon inner sheath provides anti-termite protection and the galvanized steel wire outer sheath provides anti-rodent protection. Water tightness compound within loose tube reinforced by polyster tape and jelly protects the fibers against chemical ,corrosion and moisture.Fire Rating

| 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 symbolises the core quantity and then 2 letters to denote the fibre type. Example of a UCFIBRE™ LTFMSMNWM SERIES FO Cable part number: LTFMSMNWM008M1 The above example describes an OM1 (62.5um, Orange Sheath) UCFIBRE™ LTFMSMNWM SERIES FO Cable, with 8 cores. | ||
