Techlogiks 2-Fiber and 4 Fiber Single Mode G 657 A1 Fiber to the Home (FTTH) flat drop cable is designed for use in aerial applications. Dielectric strength members FRP are placed parallel to optical fibres one on each side, to provide necessary longitudinal strength and one messenger steel wire is joined to form the cable construction in figure eight shape.
Standards Compliance:
Telecordia GR-20, IEC 60794, EIA/TIA, ITU-T, EN187000, RUS1755.900
Applications:
FTTH, Aerial and Duct/Conduit, Local loop, Broadband network
Advantages:
Easy Drop, Multiple network applications, Reduces cable prep and installation time, Reduces cost, Easy Installation
