Product Description

FOS sacrificial sheath dielectric loose tube 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 OM1, OM3, OM4 and Singlemode.
