Description:

Micro Blown Cables are designed to be used with the Microduct system and installed using a blowing machine for long installations. It is constructed of Fibres inside multiple gel filled loose tubes which range from 12 fibre to 288 fibre cable. The cable is strengthened by a glass reinforced plastic (GRP) strength member with a high-density polyethylene outer sheath. The exterior is UV stabilised with a 2.5% evenly dispersed carbon black. This construction gives maximum flexibility while isolating the Fibres from installation and environmental rigours. UV stabilised with a 2.5% evenly dispersed carbon black.

Cable Structure:

• Thixotropic jelly filled loose tube design.
• Tubes SZ stranded around the central strength member.
• Water blocking yarns and tape are applied for cable core water ingress protection.
• Over sheathed with Black HDPE.
• One ripcord laid beneath the sheath.
• Fibres in full compliance with ITU-T.

Application:

• Small diameter, light weight, optimized for blowing or pushing into micro ducts.
• Superior blowing performance.
• Working temperature: -20°C~+70°C.
• 25-year life expectancy.

Characteristics:

• Fibre attenuation at 1310/1550nm: ≤0.35/0.21db/km.
• Fibre linear PMD: ≤0.06ps/√km (M=20, Q=0.01%).
• Installation tensile resistance: 1.2 times cable weight, not less than 600N.
• Crush resistance: 650N.
• Water penetration: 3m sample, 1m water column, for 24h.
• Cable print: MBC, fibre count, fibre type, HFCL, production date, cable ID number, meter count.
