MSS Underground Loose Tube
Product Details:
The MSS underground loose tube cable is designed to be easily pulled into the
tight confines of a duct where flexibility and abrasion resistance are required,
and can be aerially lashed or directly buried underground.

Loose Tube Mono Tube:
Up to 24 optical fibres contained in a single, jelly filled loose tube, strengthened with flexible
non-metallic armour bonded to the inner polyethylene sheath, with an insect-resistant nylon
outer jacket. Options include additional sacrificial sheath. Surface printing includes length
marking at 1-metre intervals.
