Characteristics:
1. The precise control of the excess length of the optical fiber ensures that the optical cable has good tensile properties and temperature characteristics.
2. The loose tube material itself has good water resistance and high strength. The tube is filled with special grease to provide critical protection for the optical fiber. Good pressure resistance and flexibility.
3. The PE sheath has good resistance to ultraviolet radiation and environmental stress cracking resistance.
4. Use the following measures to ensure the waterproof performance of the optical cable
