With the release today of its next generation of Gfast chipsets, Sckipio delivers up to 2Gbit/s speeds in both downstream and upstream directions, supports up to four times as many subscribers sharing one binder and further enhances speeds through the use of 212MHz bonding for CPE and DPU.
The Sckipio SCK-23000 family has four times the vectoring capability, twice the bonding speeds and supports coordinated DTA (cDTA) for symmetric-like performance in downstream and upstream, said David Baum, Sckipio CEO.
The chipset includes cross-DPU vectoring without the need for external vectoring, allowing smaller DPUs to connect to increase vectoring port density, said Michael Weissman, co-founder of Sckipio, in an interview with UBB2020. This allows telcos to "pay as you grow," he said.
"You can start with a small box, an 8-port box, and as you grow you can add another 8-port box, then another 8-port box," he said. "Or, if you're in a larger environment, maybe you start with a 16-port box, then add another 16-port box and a third 16-port box. You can get up to 48 ports when you start with a 16-port. This means you have one third of the capital expense upfront and your return to profitability is much shorter because you only have to build the first box. You don't have to build all the boxes before you're profitable."
Telcos also can use one SKU yet create up to eight designs for different use cases, added Weissman. From an opex perspective, a service provider can use one box to validate, certify, deploy and train field installation technicians and so forth, he said. Finally, this approach enables CSPs to reverse power-feed because they can use smaller CPEs to keep the DPU live, said Weissman.
"At some point you can't make the box too big because you can't make the CPE too expensive and in some cases there may be regulatory limits on how much power you can inject before it gets too unhealthy. You can't do injected reverse power-feed on a 48-port box. It requires too much power," he said. "With cross-DPU vectoring, I can use a 16-port box, have a single subscriber, power up that 16-port box; I can add another 16-port box, have another single subscriber and power up that box. I can add another 16-port box. I'm at 48 ports but I'm only having to power up 16-port boxes, which is very do-able with the current limits from ETSI, the capabilities of the system and the low power requirements of our chips. So what that means is you can actually get to 48-point vectoring at 212 in a way that literally was not possible before."
The chipset is designed to help operators further compete against cable companies' rollouts of DOCSIS 3.1, said Weissman. In part, it does this by featuring cDTA support beyond 1 Gbit/s in upstream and downstream. (See DT, ADTRAN Lab Test Super-Speedy G.fast .)
This allows service providers to deliver gigabit service to consumers without installing costly, time-consuming fiber-to-the-home (FTTH). And, if CSPs combine cDTA with bonding, resulting speeds hit 2 Gbit/s, said Weissman.
Some service providers will offer bonding-as-a-service (in fact, six months ago Windstream announced a partnership with Sckipio to provide this offering), he said. Others will use bonding to bring high-speed Internet to subscribers plagued by poor bandwidth due to something in the their home or a regional problem, Weissman said.
Speedier Gfast also empowers service providers to resolve the urban digital divide, he said. Although Gfast might not answer rural broadband problems due to a lack of copper and long distances, cities are prime candidates for next-generation Gfast, Weissman said. (See Disconnected in the City.)
"In the urban environment, there is also a digital divide between the rich and the poor. Gfast is the best solution," he claimed.
On Jan. 23, Broadband World News hosts a Calix-sponsored webinar that explores several ways CSPs can enhance customer experience and find new business opportunities to avoid devolving into a speed race where nobody wins, not even the customer.
As the pool of savvy, fiber-rich operators across the US rural and regional landscape wanes, the financial community will grow even more interested in acquiring or investing in them, a CoBank report says.
It wasn't long ago that TV was ranked by subscribers as the most important service in the bundle provided by their communications service provider (CSP). Recent research indicates that for nearly three quarters of subscribers, broadband is now the most important service. Broadcast TV is the most important service to only 15% of North American consumers, replaced by OTT video streaming platforms like Netflix, Amazon Prime and Disney+. In addition, many different competitors are moving aggressively to stake a claim in consumers' homes.
In 2020, CSPs need to fight back by transforming their business models, which are becoming more reliant on a single source of revenue: fixed broadband services.
This webinar will focus on helping CSPs transform their business models by placing a firm focus on delivering a sensational subscriber experience and by offering compelling new services that generate value for subscribers. These actions will reinforce the CSP's strategic position in the home network and position themselves for growth in the next decade.
Key topics include:
Being the first to market with WiFi 6 technology, in response to consumer purchases of new devices over the holidays;
Having the insights needed to proactively resolve issues, often before your subscribers even know that there are issues;
Providing help desk agents with the visibility they need to resolve common subscriber issues more quickly;
Delivering a mobile app, in response to consumer demands for the ability to do some things themselves, rather than having to call technical support; and
Addressing consumer concerns around device security, privacy and control with enhanced security and parental controls.
In this insightful Light Reading radio show, Kurt Raaflaub, Head of Strategic Solutions Marketing, will outline the key service provider challenges, deployment considerations, next-gen Gigabit technologies, and service models to win market share in the rapidly growing MDU market.
