URL	/flat-drop-cable/
Also known as	Flat drop cable, FTTH flat drop cable, butterfly drop cable, flat fibre drop cable, indoor drop cable, toneable flat drop cable
Parent page	Fiber Optic Cable

Key Features

Flat, compact profile — routes along walls, behind panels and through tight conduit

Two parallel strength members protect the fibre against crush and pull

Bend-insensitive fibre for the tight corners that real subscriber routes have

Dry construction — no gel or filling compound to clean out at the splice point

LSZH jacket — low smoke, halogen-free

Supplied in standard, figure-8 self-supporting, toneable and pre-terminated versions

Cable Variants

Variant	Construction	Where it is used
Standard flat drop	Two parallel strength members, fibre in the centre	Wall-mounted runs, indoor routing, short aerial spans
Figure-8 self-supporting	Flat drop plus a steel messenger in one jacket	Aerial spans — no separate support wire needed
Toneable flat drop	Flat drop plus a metallic tone wire	Buried and ducted drops that must be located later
Pre-terminated flat drop	Any of the above with factory-fitted connectors	Plug-and-play subscriber connections

Confirm which of these variants we actually produce before publishing. See Values to Confirm.

Applications

FTTH drop from the access terminal to the subscriber premises

Indoor routing in apartment blocks and multi-dwelling units

Aerial last spans, using the figure-8 version

Buried and ducted drops, using the toneable version

Wall-mounted and façade runs

How to Select

Confirm the route first. Indoor, aerial, buried or ducted — the route decides the cable variant before anything else is chosen.

Match the variant to the route. Aerial spans need the figure-8 version; buried or ducted routes need the toneable version if the cable has to be located later.

Confirm the fibre count and type. One or two fibres is normal for a drop; higher counts are used in multi-dwelling units. Confirm bend-insensitive fibre for tight bends.

Check the mechanical figures against the pull. Tensile load and minimum bend radius have to suit how the cable will actually be installed, not just the datasheet.

Confirm termination. Factory-fitted connectors save time on site; bare ends suit field splicing.

Frequently Asked Questions

Flat drop cable or round drop cable?

Flat drop is thinner and easier to route along surfaces, which makes it the usual choice for the subscriber drop. Round drop cable bends more freely and is often used for riser and conduit work.

What does “toneable” mean?

A metallic tone wire runs inside the cable, so the route can be found with a tone generator and probe. It is what makes a buried or ducted drop findable later — the same idea as detectable pull tape, applied to the drop cable itself.

Why use bend-insensitive fibre?

Subscriber routes have tight corners, and a conventional fibre loses signal when it is bent sharply. G.657.A1 or A2 tolerates a much smaller bend radius, which is what makes the compact flat design workable at the premises end.

Is it all-dielectric?

The FRP version is — it contains no metal. The figure-8 version contains a steel messenger, so check whether your route requires electrical isolation before specifying it.

Can it be installed in the same duct as other services?

That depends on local rules and on whether the cable is all-dielectric. Tell us the route and the services already in it and we will confirm.
