Ordering Information
UCFIBREâ„¢ UTM SERIES FO Cable part numbers are made up using the table below.The part number always starts with the letters UTM to denote that it is a UCFIBREâ„¢ UTM 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„¢ UTM SERIES FO Cable part number: UTM006M2 The above example describes an OM2 (50um, Orange Sheath) UCFIBREâ„¢ UTM SERIES FO Cable, with 6 cores.
