CSTA cable has a similar design to Loose Tube cable but it can be use for direct burial applications and offers protection against rodent damage. The cable consists of an internal loose tube, within this tube there is a bundle of 250um fibres that either have a gel or water absorbent powder to protect the fibre against water ingress, there is a Kevlar yarn then a Steel Tape for extra protection and then a UV stable LSZH outer sheath. |
