7.0mm duplex armored indoor fiber optic cable use 900μm tight buffer as optical communication medium. The tight buffer is surrounded with aramid yarn, which is wrapped with LSZH as the inner jacket. A layer of braided steel wire is applied over the inner jacket, then the cable is completed with HDPE as outer sheath .
