Pre-terminated Bow-type Drop Cable: A bow-type drop cable with pre-installed plugs at one or both ends manufactured in the factory.
The optical cable has a compact structure and excellent high and low temperature performance.
The strength member adopts high-carbon steel wire, featuring superior tensile performance.
The fiber reinforcement has excellent bending performance.
Products can be designed according to customers' specific requirements.
The sheath is made of low-smoke and halogen-free material.
It has superior flame-retardant performance.
