Ordering Information
UCFIBRE™® LTZMSM SERIES FO Cable part numbers are made up using the table below.The part number always starts with the letters LTZMSM to denote that it is a UCFIBRE LTZMSM™® 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™® LTZMSM SERIES FO Cable part number: LTZMSM008M2
