Ordering Information
UCFIBRE 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 UCFIBRE UTM 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 UTM SERIES FO Cable part number: UTM006M2 The above example describes an OM2 (50um, Orange Sheath) UCFIBRE UTM SERIES FO Cable, with 6 cores.
002 : 2 cores 004 : 4 cores 006 : 6 cores SM - SINGEMODE, G652D, 9um (Yellow sheath) M1 - OM1, 62.5um (Orange sheath) M2 - OM2, 50um (orange sheath) M3 - OM3, 50um (aqua sheath) M4 - OM4, 50um (aqua sheath)
