BlownIn

BlownIn is a multitube design that can have up to 432 fibers. It is an all-dielectric and UV-resistant micro air blown cable suitable for indoor and outdoor cable conduits and trays. These cables typically consist of a stranded core with central strength element (FRP), gel-filled loose tubes with optical fibers and PBT fillers (where applicable). The stranded core is fixed by water-swellable yarns. Operation tension can reach up to 225 lb (1 kN) and installation tension can be up to 674 lb (3 kN). It also has a wide range of operating temperatures from -40°F to +158°F and installation temperatures from -22°F to +122°F.

BlownIn cables can be manufactured in several options:

Option PE 250

• 250 μm fiber
• HDPE outer jacket

Option PA 250

• 250 μm fiber
• PA outer jacket

Option PA 200

• 200 μm fiber
• PA outer jacket

Option PA 200 Reduced

• 200 μm fiber
• PA outer jacket
• Decreased design (up to 48 optical fibers)

Different designs comparison:

• 250 μm fiber and HDPE outer jacket: 5.6 – 11.2 mm
• 250 μm fiber and PA outer jacket: 5.1 – 10.7 mm
• 200 μm fiber and PA outer jacket: 4.5 – 9.3 mm
• 200 μm fiber and PA outer jacket (decreased design (up to 48 OF)): 3.6 mm

250 μm fiber:

• Price — lower
• Standard diameter of 12 OF loose tube, mm — 1.4
• Application — simple tasks, when there is no strict diameter limit

200 μm fiber:

• Price — higher
• Standard diameter of 12 OF loose tube, mm — 1.2
• Application — strict diameter limit, cable with 250 μm OF doesn’t fit
