# Compact Fully Dry Tube Loose Tube Optical Fibre Cable


Compact fully dry loose tube optical cable (12–432F) with PE jacket, FRP central strength member and gel-free dry tubes — engineered for outdoor duct, lashed aerial and jetting installation.


This Compact Fully Dry Tube Loose Tube Optical Fibre Cable family is optimised for Outside Plant (OSP) deployment, delivering reliable transmission performance through a durable construction and adaptability across a wide temperature range. Fibres are housed in an SZ-stranded loose tube assembly around a dielectric FRP central strength member for mechanical stability and fibre protection. Water-swellable yarns provide longitudinal water blocking, and each loose tube is gel-free (fully dry) for clean, fast handling in the field.
A black polyethylene (PE) outer jacket gives the cable the durability required for duct placement, lashed aerial runs, and jetting installation. The compact construction is lighter than conventional duct cables of the same fibre count, making it easier to handle and install across backbone, metro and access networks. Available in single-mode G.657.A1 fibre with counts from 12 to 432 fibres.
