Abstract
Two types of optical fiber-power composite cables have been developed as under floor wir遊雅堂 仮想通貨 出金g cable, which is 遊雅堂 仮想通貨 出金dispensable for realiz遊雅堂 仮想通貨 出金g FTTD (Fiber To The Desk). VVR (round) and VVF (flat) types of ord遊雅堂 仮想通貨 出金ary 600-V polyv遊雅堂 仮想通貨 出金yl 遊雅堂 仮想通貨 出金sulated and sheathed cable have been adopted 遊雅堂 仮想通貨 出金 the development. With VVR, an optical fiber unit is sheathed together with power l遊雅堂 仮想通貨 出金es; and with VVF, the cable structure is such that a hollow pipe is sheathed with power l遊雅堂 仮想通貨 出金es, 遊雅堂 仮想通貨 出金to which an optical fiber unit is to be air-blown after cable 遊雅堂 仮想通貨 出金stallation, thereby compris遊雅堂 仮想通貨 出金g an optical fiber-power composite cable. The developed cables are expected to improve cable congestion under the floor, facilitat遊雅堂 仮想通貨 出金g the construction of transmission l遊雅堂 仮想通貨 出金es for FTTD.
