CCAP+Remote PHY and the Path Towards FTTH, Unified Access and Virtualization

jchapmanBy John Chapman, Cisco Fellow, CTO, Cable Access BU

This week, we and 10,000 or so hard-core engineering colleagues within the cable industry descend upon the city once known as the cable capital of the world — Denver, Colorado — and, like it’s been since the earliest days of the Society of Cable Telecommunications Engineers’ annual Cable-Tec Expo, a trending topic, now and forever, is bandwidth.

The reasons why are obvious, but indulge me a brief recap: Consumer usage of broadband grows at an compound annual rate of 50% or more, ever since about 2009, when Netflix began streaming video, in addition to mailing DVDs. Add to that the sheer number of video-capable, IP-connected screens we all use, and the fact that video itself is only scheduled to get bigger (we’re looking at you 4K), and it’s easy to envision why it’s a considerable challenge to keep the cable infrastructure updated, and capable of ever-increasing carrying capacities.

Here in Denver, we are focused on this challenge. Big picture, we are “transforming” cable access from a DOCSIS focus, to integrate DOCSIS with service provider  WiFi, PON & FTTx, and MetroE into a single, easily- managed portfolio, which only Cisco can deliver. Doubleclicking on the DOCSIS pillar alone, we are taking the CMTS architecture and redefining it to deliver far more bandwidth, for far less cost. We see two technologies that stand out: Read More »

ANGA COM 2014 Closes on a Positive Note: Key Highlights from the Show Floor

Another successful ANGA COM for Cisco.

The event itself attracted 17,000 visitors and 1,700 participated in the Congress, listening to over 100 speakers – both areas attracting more people than last year – this is indeed a growing show!

Cisco was well represented in panels and speaking sessions throughout the event, with Alon Bernstein´s talk on virtual CMTS’, Yves Padrines’ panel on Connected & Smart Homes  - which was very well attended in spite of taking place on the last afternoon – we counted over 300 people!  And of course my own involvement on a panel to discuss how Cloud is key to keeping service provider’s competitive against new players such as the Over-The-Top (OTT) providers.

Cloud or Not to Cloud, That is the Question! from Cisco Service Provider

The Beauty of Remote PHY (And Other Infrastructure Trends at ANGA 2014)

detmanWritten By Daniel Etman, Director, Product Management, Cable Access at Cisco

One of the taller trends protruding from the cable infrastructure side of life these days, along with Software Defined Networking (SDN) and Network Function Virtualization (NFV), is the fiber optimization and convergence strategy known as “Remote PHY.

And if you’re into infrastructure trends, know that we expect the matter of Remote PHY to qualify as a genuine hot ticket at the upcoming ANGA show, in Cologne.

Why: Because as service providers with cable access assets roadmap the infrastructure portions of their strategies to provide Gigabit services (residential and enterprise), mobile backhaul, and headend virtualization, they’re finding it increasingly important to be able to use the same fiber(s) for multiple purposes.

Such desires lead directly to Remote PHY, which isn’t Read More »

A Cisco CCAP Update for Cable Show 2013: Helping Cable Operators Double Down… and Quadruple Up!

Three years ago, when I blogged about the Cable Converged Access Platform (CCAP), current events involved whether it would be called “CMAP,” “CESAR,” or something else entirely. (So much clearer in hindsight!)

Last year, when I blogged about CCAP at The Cable Show, current events centered on phasing, and how to prepare plant and infrastructure for the unified QAMs of CCAP — while the gear itself was being architected and built.

For what was Phase 1, Read More »

DOCSIS 3.1: Here’s To the Next New Thing in Broadband!

Thursday, at a specially-added session during the Society of Cable Telecommunications Engineers annual Cable-Tec Expo, another milestone was placed in the evolution of cable modems and broadband networks: The expansion of the specification, to eke even more bandwidth out of existing HFC plant.

It’s called DOCSIS 3.1, and it’s a big deal. Every chapter in the DOCSIS specification added substantially new features – from 1.0 to 1.1 to 2.0 and, the latest workhorse for IP video, DOCSIS 3.0.

DOCSIS 3.1 will take that even further. I’ll stop short of saying it’ll make Read More »
