Construction & Materials
Fiber Optics:
The cable contains optical fibers compliant with ITU-T G.652D (or as specified in the attached documentation). The fibers are color-coded according to IEC 60304 standards (red, green, blue, white, violet, orange, grey, yellow, brown, pink, black, turquoise) to simplify identification and maintenance.
Tube & Insert Identification:
The cable’s tubes (or liners) are uniquely identified – the first tube is red, the second is blue, while any additional tubes are natural in color. If an insert is present, it is marked in black.
Central Reinforcement:
At the core, a 2.5 mm diameter FRP (Fiber Reinforced Polymer) rod provides mechanical strength and supports the overall structure of the cable.
Tube Filler:
Each tube is filled with a thixotropic gel that stabilizes the internal components and helps protect the fibers from mechanical shocks.
Moisture Barrier:
A swelling (expanding) tape with an approximate thickness of 0.20 mm serves as an effective moisture barrier, preventing water ingress which is critical in damp underground environments.
Inner Jacket:
The inner jacket is made of extruded PVC (polwinit) in black (RAL 9005) with a nominal thickness of about 1.4 mm. This layer offers additional insulation and protection to the cable’s core.
Armour:
For enhanced mechanical protection, the cable is armoured with steel wires (diameter 1.54 mm). This armouring makes the cable resistant to both longitudinal and transverse stresses encountered in mining installations.
Outer Jacket:
The final layer is an extruded flame-retardant PVC (FR) outer jacket in blue, with a nominal thickness of approximately 1.5 mm. This jacket not only protects the cable from environmental damage but also provides excellent flame resistance.
Optical & Mechanical Performance
Attenuation:
The fiber attenuation is low, with values of ≤ 0.4 dB/km at 1310 nm and ≤ 0.25 dB/km at 1550 nm (for single-mode fibers), ensuring high-quality signal transmission over long distances.
Mechanical Properties:
The cable is available in various fiber counts (ranging, for example, from 4 up to 144 fibers) with corresponding mechanical specifications.External Diameter & Weight:
Depending on the fiber count and construction, the cable’s external diameter ranges from approximately 18 to 22 mm, with mass values from about 630 to 1020 kg/km.Maximum Load & Bending Radius:
It is engineered to withstand high maximum loads (e.g., up to 6000–10,000 N) and offers a low minimum bending radius—ensuring flexibility during installation (dynamic bending radii as low as around 370–460 mm and slightly higher static values).Water Penetration:
The cable has been tested according to IEC 60794-1-2-F5B (1 m sample, 1 m water column for 24 hours) to verify its resistance to water ingress.
Temperature Range:
Transport/Storage: –40°C to +70°C
Installation: –15°C to +60°C
Operation: –40°C to +70°C
These ranges ensure that the cable remains operational under extreme temperature variations typical in mining environments.
