Place of Origin: Shanghai in China


Precisely design and control fiber excess length in tube and cable lay length to optimum to ensure excellent strain property in tensile strength and temperature property.
o Tube material with good temperature property and high Youngs modulus, tube filled with compound of non-detectable separated hydrogen to ensure the long term stability in transmission for two long wavelength windows.
Small in size, light in weight and easy in operation.
Tube in the center benefits cabling bending.
Tube filled with moisture-proof compound and longitudinal folded with water swollen tape and corrugated steel tape ensure no longitudinal water penetration and radial moisture-proof.
o Two round steel wires in parallel ensure cable mechanical property in tensile strength and crush resistance.
