The GYXTW series is central tube fiver optic cable. This kind of tube is made up of fiber optic cable in the center and a loose tube which is made of high modulus material and fill with waterproof compound outside. The loose casing is covered with a double coated steel strip (PSP), and the steel belt and the loose tube are added with water resistance material to ensure the compact and longitudinal water resistance of the cable. Two parallel wires are placed on both sides to squeeze the polyethylene sheath into the cable, and ensure the tensile strength of optical fiber cable.
Just as layer stranded fiber optic cable, central tube fiber optic cable is a very commonly used optical cable too. It has good water resistance, with good mechanical and temperature performance, and compared with layer stranded fiber optic cable, it has the characteristic of small in diameter, light in weight and easy to lay.
How to choose between layer stranded fiber optic cable and central tube fiber optic cable?
If the demand for the capacity of the cable is not very big, you can just choose central tube fiber optic cable. It's much cheaper than the layer stranded fiber optic cable.
I want to use the central tube fiber optic cable, but worried about the strength, how to solve this issue.
We can add steel wire central strength member to increase the tensile strength.
