Product Description
FOS corrugated steel tape armoured 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. CST armoured loose tube is particularly suited to areas where rodents and termites are an issue and metallic construction is permitted.
Loose tube cable offers a cost-effective and rugged solution for medium and long distance external fibre runs.
FOS nylon jacket loose tube cable is available in OM1, OM3, OM4 and Singlemode.
