DT-DROP-1C-G657A1-0.5mm FRP


FTTH Cable directly connected to their homes, their bandwidth, wavelength and transmission technology type are not restricted. The optical fiber unit is positioned in the  centre. Two parallel strength member are placed at the two sides. A steel wire as the additional strength member is also applied , then the cable is completed with a LSZH sheath.
