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

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.

ARRIS Talks CCAP Migration @ Customer Leadership Forum

CCAP or Converged Cable Access Platform is paving the way for the industry’s migration towards a common video and data delivery platform.

CCAP is a hot topic at this week’s Customer Leadership Forum (CLF) for the Caribbean and Latin American(CALA) region. Mauricio Janisset, Staff Solutions Architect, mentioned in his talks this week that while CCAP defines a particular architecture, there are numerous ways to reach that converged endpoint.

The question remains: how will the industry implement CCAP?

The answer, of course, is multifaceted, but it’s important to understand that the CCAP initiative addresses a common and urgent need to enable more narrowcast QAM channels in a more dense and power-efficient footprint. Service providers with several CMTS and Edge QAM architectures rely on a range of technology suppliers and various service delivery goals—and their approaches to CCAP will vary accordingly. But while CCAP is a technology and an architecture, it is also an evolution…

Picking the right evolutionary path is critical not only for reaching the right destination, but also for ensuring that the journey matches your infrastructure, capabilities, and business requirements.

This has been the subject of many discussions in the context of CALA, this week, but for a more detailed look at CCAP considerations, check out this white paper from Tom Cloonan – our CTO, Network Solutions – and Todd Kessler – our VP Product Line Management.

CCAP and DOSCIS 3.1 Migration @ SCTE Canadian Summit 2014

SCTE_CS2014_WebinarSeries_Logo_VertThe industry’s impending migration to CCAP and DOCSIS 3.1 is atop the list of challenges for most operators.

Our Senior Director of CMTS Product Marketing, Jeff Walker, recently reviewed strategies for operators to ensure they are optimizing DOCSIS 3.0 today, and discussed preparedness for tomorrow’s 3.1 migration.

This week, John Ulm, Engineering Fellow of Broadband Systems and a member of the CTO-Network Solution team, will shed light on these points and more at the Society of Cable Telecommunications Engineers (SCTE) Canadian Summit 2014 Webinar Series.

Specifically, John will outline migration paths to full CCAP functionality and  discuss current bandwidth capacity trends to see when HFC might run out of gas. John explains the taxonomy around today’s key cable network architecture discussions: Integrated vs. Distributed Systems and Analog vs. Digital Optics. A detailed analysis is given of the limits of Integrated CCAP + analog optic Head Ends; followed by a discussion of distributed architectures such as Remote PHY and Remote CCAP with their relative benefits.

Mark your calendars for Tuesday, June 24th at 2 p.m. EST. This exciting discussion is surely one you will want to attend. Register here ASAP.

LIWEST selects ARRIS E6000™ for Better Broadband

We just announced that LIWEST will be using our E6000™ Converged Edge Router (CER) to enable future high-speed broadband services of up to 1Gbps to its subscribers in Austria.

The deployment makes LIWEST the latest operator in a growing group of global leaders that have selected ARRIS and the E6000 to future-proof content delivery. Research firm Infonetics recently named ARRIS the leader in this industry-wide shift to the Converged Cable Access Platform (CCAP), citing the sector’s 177% revenue growth and ARRIS’s global lead in the first quarter of 2014.

LIWEST will use the E6000 CER in tandem with our TG682 cable modem/gateway, which is already widely deployed to its subscriber base. This IP infrastructure allows LIWEST to achieve smarter, more efficient networks that can scale to tomorrow’s super-fast broadband speeds and the demands of new, advanced services.

ARRIS Speakers Demonstrate Technical Thought leadership at ANGA

Walking the floor at ANGA, you don’t see any programmers: this conference is all about the technology. This year, four ARRIS speakers drove that conversation on a variety of subjects, from CCAP to Wi-Fi…

Engineering Fellow John Ulm led off, joining a heavyweight panel, including Jorge Salinger of Comcast, in a wide-ranging examination of Converged Cable Access Platform (CCAP) spec and upcoming potential offshoots from the original spec. Introduced by moderator Daniel Howard, CTO of the SCTE, as ‘the father of the DOCSIS MAC protocol’, Ulm laid out the current state of CCAP and then progressed to the pros and cons of its potential offspring: Remote PHY and Remote CCAP. Service providers will have several options to ensure the continued reliability and increased capacity of their networks, options which are dependent on deployment timing, headend space and powering constraints, new generations of silicon, and individual network architectures.

On Day Two, ARRIS CTO of CPE Charles Cheevers addressed the increasingly critical subject of Wi-Fi optimization. Consumers continue to experience a gap between advertised speeds and the actual experience, especially within the home. There, issues of building construction, user overlap (especially within MDUs), and contention between a competing and constantly increasing number of devices are impacting real-world results.

Cheevers proposed the concept of deterministic Wi-Fi delivery, prioritizing usage and implementing a remote resource management system to create a self-organized network within the home Wi-Fi domain to improve the customer experience.  Finally, he previewed the anticipated 802.11 AX, a next-generation Wi-Fi spec that seeks to deliver a 4X improvement in efficiency. It will be a welcome release, coming in at a time when 4k television will be widely-adopted, requiring bitrates between 15Mbs-30Mbs, and 8k will be waiting in the wings, with bitrate needs from 30Mbs-60Mbs.

Cornel speaking

 

Day Three featured Cornel Ciocirlan, ARRIS Regional Chief Technologist, speaking on the Conference’s Connected Home Summit. Panelists discussed global device proliferation (8-10 per user in Western Europe), smart/connected home technology, security concerns, and the need to educate consumers on the cost-value equation.

By 2020 there will be 50 billion devices connected to the Internet, necessitating a commensurate network infrastructure.  Ciocirlan pointed out that the “killer app” driving broadband growth currently is video content consumption, and that the industry needs to develop a killer app for the connected life: machine-to-machine interaction will not drive broadband growth.  As service providers become software companies, they will need to better understand how the Internet of Things will affect the consumer.

Rounding out Day Three, ARRIS Sr. Director of Marketing, Duncan Potter, presented a paper on Dynamic ABR Format Repackaging to optimize network infrastructure. With the increasing number of devices able to consume video expected to reach 7 Billion by 2017, the impact of multiscreen on operator video infrastructure costs has far outstripped the ability of caching to reduce the cost of that video distribution.  Potter referenced a case study conducted with a major US service provider to mitigate the costs of storage, packaging, and backhaul by using dynamic repackaging from a single format such as Apple HLS to whatever the client requires, at various points in the network.

Some food for thought as we close out ANGA. Check back for more from Canitec and beyond.
