Comcast hits 4 Gbps symmetrical in DOCSIS 4.0 test with CommScope

In lab testing of DOCSIS 4.0, Comcast achieved a peak speed exceeding 4 Gbps symmetrical. The trial used CommScope MiniBridger FDX amplifiers in a six-amplifier cascade to emulate a typical plant design.

CommScope said the result highlights a multi-year FDX amplifier development effort between the two companies that has also resulted in the development of CommScope’s DOCSIS 4.0 OM6000 node with RD1710-X6 FDX Remote PHY Device (RPD).  These provide a module-only upgrade path to DOCSIS 4.0 FDX in an open-standards environment. In the case of Comcast, they will serve as direct upgrades to the installed base of CommScope STARLINE®-series MB amplifiers and OM6000 nodes already deployed in the field

“DOCSIS 4.0 is ushering in a new era of speed and reliability for consumers and businesses. As we begin to introduce it to our customers, we’re continuing to innovate and push the limits of what HFC networks across the globe can achieve,” said Elad Nafshi, Executive Vice President, Chief Network Officer, Comcast Cable. “Leveraging our installed base of CommScope amplifiers and nodes to achieve even faster symmetrical Internet speeds helps ensure that we can efficiently deliver the best broadband experience to our customers for years to come.”

“CommScope has an incredible legacy of pioneering leadership with the DOCSIS architecture, and this milestone DOCSIS 4.0 FDX lab test with Comcast is further proof that we’re on the leading edge of HFC network technology,” stated Guy Sucharczuk, SVP and General Manager, Access Network Solutions, CommScope. “Our line of STARLINE-Series MB amplifiers, combined with our OM6000 node and RD1710-X6 FDX RPD, will give operators a means to extend their network capabilities well into the future, leveraging their existing investments and infrastructure, while reducing costs and downtime. This is just one way that CommScope’s innovation is empowering our customers’ network evolution, whatever their chosen path may be.”

Windstream Wholesale builds new 432-fiber route from Montreal-NYC

Windstream Wholesale cites progress with its CanAm2 fiber build, a 440-mile, long-haul route comprising 432 new fibers from Montreal, Canada, through Albany, New York, and on to New York City. 

A major construction milestone between the New York state border and Montreal, Canada, is now complete and open for business.

Windstream Wholesale’s CanAm2 employs a distinctive cross-border architecture that offers increased availability of dark fiber, meets the growing demand for high-capacity transport from customers, and has already been purchased by several major hyperscalers to gain a competitive advantage. CanAm2 provides a new and unique route design that will link Montreal and New York City while also providing access to networks in Boston, Massachusetts, via Albany, another critical network junction supporting the westbound corridor to Buffalo, New York, and connection points west.

Windstream Wholesale credits its progress on the CanAm2 route to leveraging two key qualified partnerships:

* Telecon, an industry-leading North American telecom infrastructure turnkey solutions provider, for the route build within Canada, and

* HYLAN, a leading provider of full-service turnkey communications solutions, for the route build within the U.S., from the Canadian border to New York City.

“The Windstream and Telecon teams have been collaborating very efficiently on the CanAm2 project, always seeking ways to innovate to ensure the delivery of a high-quality network. Telecon built the Canadian part of the conduit used to deploy fiber on this project in prior years, so this partnership felt particularly natural.

Credo intros HiWire Pluggable Patch Panel

Credo Technology introduced its HiWire Pluggable Patch Panel (HiWire P3) enabling the decoupling of pluggable optics from core switching and routing hardware using Credo’s HiWire Active Electrical Cables (AECs).

The HiWire P3 is a single rack unit (1RU), 32 port QSFP-DD appliance that allows standard pluggable optics to directly connect to an AEC without the use of a switch chip. The HiWire P3 provides power, cooling, and control plane access supporting three important use cases:

  1. Enabling coherent optics such as ZR+ to be used on lower-cost and smaller buffer switches which may currently lack the power and cooling envelope, or the software required to directly support them.
  2. Enabling switch and router port speeds to be decoupled from optics speed without having to slow ports down, thereby sacrifice radix and cost, through the use of speed shifting AECs.
  3. Enabling EDFA amplifiers to be hosted in HiWire P3 ports at lower-cost and lower-power overhead, rather than consuming valuable switch or router ports.

“The HiWire P3 enables complete flexibility in the deployment of modern pluggable optics with new and legacy switches and routers,” said Don Barnetson, Vice President of Product at Credo. “In the HiWire P3, all of the capabilities of the modern pluggable optics are transparently exposed to the user in an open management platform without the increased power, latency, cost and complexity of a switch.”

ADTRAN announces preliminary Q3 revenue of $272M

ADTRAN announced preliminary Q3 2023 revenue of $272.3 million as compared to the Company’s prior guidance range of $275 million to $305 million. The resulting preliminary GAAP operating margin for the third quarter was -30.2%, and it was impacted by certain one-time adjustments that are outlined below. Preliminary non-GAAP operating margin for the third quarter was -1.9%, which is at the upper end of the company’s guidance.

ADTRAN said the total customer count continued to grow in the third quarter of 2023, however, it believes that customers will manage their inventories conservatively and adjust their capital expenditure budgets in the fourth quarter in response to the changed economic environment.

ADTRAN Holdings’ Chairman and Chief Executive Officer, Tom Stanton, stated, "While revenue and GAAP operating margin continue to be challenging as customers remain focused on reducing inventory levels and managing capital expenses, our Q3 non-GAAP operating margin was at the upper end of our guidance, helped by the planned reduction in our operating expenses and improved non-GAAP gross margins. Additionally, the strengthened U.S. dollar had a negative impact on revenue generated outside of the U.S. Moving forward through the end of this year, we will continue to focus on aligning our operating model to reflect the current environment. Finally, during the third quarter, ADTRAN continued to add new customers in both Europe and the U.S., further strengthening our market share position and, with our broad portfolio and geographic reach, uniquely positioning us to benefit from what we anticipate to be a return to normalized spending.”

Final results for Q3 2023 will be released as planned on November 6, 2023.
