This document specifies the product model, structural parameters, manufacturing length and performance requirements of butterfly optical cables (hereinafter referred to as optical cables), and describes the corresponding test methods, inspection rules, packaging, marking and. 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. This cable is mainly used for interconnecting cable for. Remote base station communication such as RRU or BBU and Smart substation and CATV Outdoor application. Emergency access to optical fiber communication. Used in FTTX, from residence to data center and cabling level and vertical, also used in FTTH cable. Central loose tube cables and self-supporting FTTH drop cables are desinged for outdoor aerial distribution.
