Steel Tape Armoured Fibre Cable
Steel tape armoured (CST) fibre cable adds a corrugated steel tape layer for mechanical protection and rodent resistance, supplied in OM1, OM3, OM4 and OS2 fibre in 4 to 24 core counts.
Steel tape armoured fibre cable, often called CST, is a rugged optical cable built with an added layer of corrugated steel tape for extra mechanical protection and rodent resistance in demanding environments.
Choosing steel tape armoured fibre cable
Select the fibre category to match the rest of the link: OM1 62.5/125 and OM3 or OM4 50/125 for multimode runs, or OS2 9/125 singlemode for longer distance links. Core counts run from 4 up to 24 core, so choose a size that covers current outlets plus reasonable spare capacity for the route.
- Fibre categories: OM1, OM3, OM4, OS2
- Core counts: 4, 8, 12, 16 and 24 core
- Construction: corrugated steel tape armour
This sits within the wider fibre optic cable range alongside Steel Wire Armoured Fibre Cable and unarmoured Loose Tube Fibre Cable for installers who do not need armour.
Steel Tape Armoured Fibre Cable FAQs
What is steel tape armoured (CST) fibre cable used for?
CST cable is used where the fibre run needs extra mechanical protection and resistance to rodent damage, such as external ducts or exposed outdoor routes, thanks to its corrugated steel tape layer.
Which fibre categories are available in steel tape armoured cable?
This range covers OM1 62.5/125 and OM3 or OM4 50/125 multimode, plus OS2 9/125 singlemode, in core counts from 4 up to 24 core, so you can match the category already used elsewhere on site.
How does steel tape armoured cable differ from steel wire armoured cable?
Both add mechanical protection for harsh runs, but they use different armour constructions. See Steel Wire Armoured Fibre Cable for the alternative build.
