Sacrificial Sheath Loose Tube
- Bonded triple jacketed construction - excellent resistance to termites and external damage
- Insect resistant intermediate nylon layer with physical protection of the added outer layer
- UV stabilised polyethylene inner and outer jacket for long life in a wide range of installations
- Water swellable yarns provide protection against water ingress (dry core construction)
- Non-metallic construction
- Fibreglass reinforced polymer central strength member and glass yarn peripheral strength member provide excellent strength
- Flexible buffer tubes provide easy handling within termination enclosures
- Single layer SZ stranding limits stress on fibre tubes
- Underground ducts
- Direct buried fibre links
- Inter-building links
- Campus fibre networks
- Infrastructure and industrial fibre links
- Termite or insect prone areas
FOS sacrificial sheath dielectric loose tube fibre cable is suited to external underground installations in ducts by pulling, jetting or floating techniques or by direct burial in open-cut
trenches.
Sacrificial sheath loose tube cable offers all the benefits of our standard nylon jacket loose tube, with the addition of a tertiary polyethelene jacket. This extra coating offers extra UV and impact protection to the termite resistant nylon jacket and limits any potential significant non-superficial damage to the cable.
FOS sacrificial sheath loose tube cable is available in black outer jacket in OM1, OM3, OM4 and Singlemode.
