CommScope yesterday announced what the company is calling the industry’s first 204 MHz digital return, enabling operators to deploy a high split in their upstream band and deliver new gigabit speeds. The digital return solution consists of the CommScope DT4600N node transmitter and DR3600N headend receiver. Together, they establish an optical link that delivers consistent performance across all link distances between CommScope’s NC4000, NC2000 and OM41x0 node platforms and its CH3000 headend optics platform.
CommScope’s high-split (204MHz) digital return enables operators to evolve their networks, building on an installed base of optical nodes to fully capture the benefits of DOCSIS 3.1. By implementing a high split with digital return, operators will be able to consistently deliver higher upstream bandwidth and faster upload speeds, irrespective of link distance, according to CommScope. The company says digital return is the only practical way to achieve the high link performance required for a fully loaded 5-204MHz upstream utilizing 1024-QAM or even higher – independent of distance, up to and even beyond 100km.
“Our new 204 MHz digital return is the first of its kind, and one of the most highly anticipated solutions to support upstream bandwidth expansion,” said Guy Sucharczuk, senior vice president, Access Technologies, Broadband Networks, CommScope. “With a high-split network, operators can address the tremendous bandwidth demands and the need for 1 Gbps upstream speed to meet the new global environment head-on. The new DT4600N and DR3600N build on CommScope’s proven digital return platform, offering operators a simple path to additional capacity and their network of the future.”
