Bow-type Duct Fiber Optic Drop Cable

FTTH drop cable, also known as butterfly or indoor drop cable, is specifically designed for the final segment of fiber-to-the-home (FTTH) networks. Its structure typically features a central fiber unit reinforced by two parallel strengthening elements (such as metal wire, non-metallic FRP, or KFRP), with an additional outer steel wire hanger, all encased in a low-smoke, zero-halogen (LSZH) sheath. This design ensures robustness while maintaining a lightweight profile. The cable usually contains a small number of fiber cores, typically ranging from 1 to 4, but can be increased up to 12 cores to meet higher demand. This makes it well-suited for short-distance transmission and indoor cabling applications. The cable is highly flexible and lightweight, facilitating installation in tight bends and confined spaces, which is particularly advantageous in residential and office environments. It exhibits excellent tensile and lateral pressure resistance, with the strengthening elements ensuring stability and reliability during installation. Constructed from flame-retardant, low-smoke, zero-halogen materials, it offers enhanced safety by minimizing smoke and toxic gas emissions in the event of a fire, protecting both personnel and property. As a critical component of FTTH networks, it forms the link between the user access point and the terminal, delivering high-speed, stable internet connectivity. Beyond FTTH, it is also widely used in other fiber access networks like fiber-to-the-office (FTTO) and fiber-to-the-building (FTTB), as well as in indoor cabling for homes, offices, and data centers, where its flexibility, lightweight, strength, and pressure resistance make it an ideal choice.
