The FTTH Drop Fiber Cable is also called butterfly optical cable because it looks like a butterfly in cross section. It has the advantages of small outer diameter, light weight, low cost, reliable performance, and easy installation. It is the leading product for fiber optic cable in the construction of FTTH network. With the continuous advancement of FTTH construction, the demand for butterfly optical cables has also increased year after year, home digitalization will further develop, and butterfly optical cables will also be more widely used.
- The cable consists of optical communication unit, strength member, self-supporting unit and outer sheath;
- Optical communication unit includes fibers or tight buffer fibers;
- Strength member can be metallic or Non-metallic according to customers' demand.
