ZTT DAC 2J 9/125 G.657A1 is designed for direct underground installation. The cable has an HDPE sheath with high crushing resistance (1500 N). Cables with such sheath are also resistant to low temperatures. It can be used on the last mile of a FTTH system, as well as any installation that requires in ground connections, where casing pipes cannot be used for additional protection.
The cable can also be installed in existing tubing, with the maximum installation tension of 1200 N.
The central tube contains 2 single-mode G.657A1 fibers.
The central tube is filled with gel to protect fibers from moisture and vibration and the cable itself has a water blocking structure (WB). The cable is reinforced with two 0.5 mm diameter FRP bars.
Despite its high mechanical resistance, the cable is very easy to process. No dedicated tools are required to remove the outer sheath: a simple cleaver (to perform a cut of several centimeters along the central tube) and a pair of pliers (to tear up the outer sheath with FRP rods) are all you need.
