Cable preps for symmetrical multi-gig speeds

DENVER –Racing to deliver symmetrical multi-gigabit speeds over its HFC networks, the cable industry is moving quickly to craft a next-gen version of its DOCSIS broadband standard for introduction as early as sometime next year.Formally known as Full Duplex DOCSIS 3.1, or FDX, the forthcoming tech spec is designed to support data speeds as high as 10 Gbps in either direction. It aims to make use of a technology called "echo cancellation" to allow upstream and downstream signals to travel over the same spectrum at the same time.Speaking at the SCTE/ISBE Cable-Tec Expo show in Denver late last month, industry...
