Blown Fibre Tube Cable
Small diameter low friction tubes provide the dedicated pathway for the
optical fibre units, integral to the Sirocco system. Empty HDPE tubes are available in a variety of
sizes, combinations, and protective systems. The Sirocco tubes have all been rigorously tested and
enable the Sirocco units to be blown the optimum distance within the tube network. A comprehensive
range of jointing accessories is available for tube-to-tube connections, gas and water blocking.
Blown tubes are available in a range of sizes although the standard tube size for Sirocco is
5mm outside diameter and 3.5mm inside diameter. The tubes are assembled to form multi-tube units
with up to 24 in a single cable. These are incorporated as :
• Direct Install Cable (Duct)
HDPE low friction tubes of small diameter for blown fibre installations in ducts and
sub-ducts.
Features and Benefits
- Recommended for use in ducts and sub-ducts.
- Aluminium tape layer acts as a moisture barrier.
- Rapid dedicated customer connections using proven mechanical protection of HDPE.
- Low friction internal coating for maximum fibre blowing distance.
- Each tube accommodates one fibre unit (up to 12 fibres in a unit).
- Can be customised to suit user requirements (e.g. tube style, sheath colour, print
legend).
• Direct Bury Cable
HDPE low friction tubes of small diameter for blown fibre installations in Direct Burial
applications. The heavier construction lies flatter in trenches, has increased crush rating and has
more resistance to localised bending. For external application, a range of alternative protection
systems can be provided for different applications, depending upon the environment. The most
popular options are:
Features and Benefits
- Recommended for direct burial in prepared ground.
- Aluminium layer acts as a moisture barrier.
- Double sheath to improve crush and bending resistance.
- Lower total installed cost compared with installing tube cables in larger bore ducts.
- Rapid dedicated customer connections using proven mechanical protection of HDPE.
- Low friction internal coating for maximum fibre blowing distance.
- Each tube accommodates one fibre unit (up to 12 fibres in a unit).
- Can be customised to suit user requirements (e.g. tube style, sheath colour, print
legend).
• Direct Bury Non-Metallic Cable
HDPE low friction tubes of small diameter for blown fibre installations in last-mile and campus
environments. For Direct Burial applications where lightning incidence and other influences
establish preference for a totally non-metallic cable.
Features and Benefits
- Totally non-metallic solution.
- Recommended for direct burial in prepared ground.
- Water swellable tape layer acts as a moisture barrier.
- Lower total installed cost compared with installing tube cables in larger bore ducts.
- Rapid dedicated customer connections using proven mechanical protection of HDPE.
- Low friction internal coating for maximum fibre blowing distance.
- Each tube accommodates one fibre unit (up to 12 fibres in a unit).
- Can be customised to suit user requirements (e.g. tube style, sheath colour, print
legend).
• Internal Cable (LSOH)
LSOH low friction tubes of small diameter for blown fibre installations in buildings.
Features and Benefits
- LSOH indoor version with flame retardant properties (IEC 60332 Part I & III).
- Low smoke emissions BS 7211 (Ap.d).
- Contains no halogens.
- Low friction internal coating for maximum fibre blowing distance.
- Each tube accommodates one blown fibre unit (up to 12 fibres inside).
- Tubes are numbered for easy identification.
• Internal Cable (OFNR – UL Riser Rated )
Low friction tubes of small diameter for blown fibre installation in building risers as
specified by NEC article 770-51(b) and 770-53(b). This cable is UL listed type OFNR.
Features and Benefits
- Suitable for ‘Riser’ applications where flame propagation characteristics are required in
accordance with NEC article 770-51(b) and NEC 770-53(b).
- UL listed type OFNR.
- Low friction internal coating for maximum fibre blowing distances.
- Tube cable configurations available: 1, 2, 4, 7, 12, 19 & 24 way.
- Each primary tube, 5 mm OD x 3.5 mm ID, accommodates one fibre unit
(up to 12 fibres inside).
- Solid white/cream coloured tubes.
- Print details include batch number, meter count and individual tube number.
