Systel 2-Fiber and 4 Fiber Single Mode G 657 A1/A2 Fiber to the Home (FTTH) flat drop cable is designed for use in aerial applications. Dielectric strength members FRP are placed parallel to optical fibers 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.
Standard 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.
