FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Can 200 µm (SiroccoHD) and 180 µm (SiroccoXT) fibres be fusion-spliced to standard 250 µm telecom fibres?

Yes. Only the external polymer acrylate coating is reduced from 250 µm to 200 µm or 180 µm; the underlying silica glass cladding remains the universal 125.0 µm ± 0.7 µm diameter. Once stripped, they fusion-splice directly to any standard G.652.D or G.657 fibre using standard core-alignment splicers.

How do Sirocco, SiroccoHD and SiroccoXT differ?

Standard Sirocco uses 250 µm fibres (up to 288F) and 2–12F EPFU blown fibre units. SiroccoHD uses 200 µm bend-insensitive G.657.A1 fibres to pack up to 864 fibres into a 9.7 mm cable. SiroccoXT uses 180 µm G.657.A2 fibres to achieve world-record density—such as 288F in Ø 5.5 mm (for 8 mm ID ducts) and 552F in Ø 7.9 mm (for 10 mm ID ducts).

What drum lengths are supplied to eliminate mid-span splice chambers?

We supply continuous splice-free lengths of 2,000 m, 4,000 m, 6,000 m and up to 8,000 m per drum.

Can Sirocco microcables also deliver DC power to remote 5G small cells or Wi-Fi APs?

For applications requiring both air-blown optical fibres and remote copper DC power in the same microduct, specify our companion SiroccoHYBRID Composite Fibre-Optic and Copper Power Air-Blown Microcable.
