ARRIS Announces the Death of OBI, Solving Cable’s Decade-Long Dilemma

22 Sep 2014

Cable operators began using RF over Glass (RFoG) ten years ago to expand their HFC networks with No_OBIFTTH offerings. The primary challenge for RFoG is what is called Optical Beat Interference (OBI)—a chronic performance issue caused by multiple modems communicating at the same time over the same fiber.

OBI has plagued fiber deployments and prevented mass rollouts for the past decade, because it created unpredictable performance, which worsened as providers added more upstream bandwidth to their networks. Despite several attempts to mitigate the problem, OBI persisted, rendering fiber upgrades costly, inefficient and non-scalable. The advent of DOCSIS 3.1 exacerbated the situation, increasing upstream which magnified OBI.

Today, ARRIS unveils AgileMax™, the industry’s only FTTP, RFoG solution that completely eliminates OBI.  The ARRIS AgileMax engine supports split ratios, reaches, and data rates that were previously unachievable, while being completely transparent to xPON solutions. While this alone puts AgileMax in class by itself, it’s further differentiated as CMTS, ONU, and cable modem agnostic—making it the most cost-effective and operationally efficient solution available.

Here’s what John Caezza, President of ARRIS Access Technologies business had to say about it: “We weren’t satisfied with the temporary and operationally complex OBI solutions on the market, so we set out to develop a complete yet simple solution that operators could use to make a seamless transition to DOCSIS 3.1 and PON. ARRIS AgileMax not only delivers on all of those promises, but exceeds the performance of all other RFoG solutions.”

To learn more, stop by SCTE Booth #1764 this Tuesday through Thursday. The ARRIS team would love to answer your questions about AgileMax and talk with you about the company’s complete DOCSIS 3.1 solution, including an industry-leading CMTS/CCAP family.
