  • Butterfly Core Optical Cable

    Butterfly Core Optical Cable

    The highly flexible fiber optic cable features a structure with two single-core fibers surrounded by reinforcing elements, making it suitable for the transmission of optical signals at a wavelength of 1310 nm. FTTH Butterfly Optic Cables were designed to eliminate those compromises. The name comes from the cross-section: a flat, wing-shaped profile with the optical fiber sitting in the center and two parallel strength members flanking it on either side. These are used to provide links to protocols such as FTTH, FDDI, 10 Gigabit Ethernet, ATM.
