CommScope's new DAA aggregator, Soft EDD, DOCSIS timing protocol

CommScope announced three technology breakthroughs that improve performance at the core, throughout the access layer, and at the edge:


  • DAA Aggregator – This massively scalable new architecture extends fiber deeper into the network, lowers total cost of ownership, and requires relatively minor changes to existing fiber deep networks. The change significantly increases the number of homes passed per RPD serving group – from 20 to 40 to between 150 to 300 – enabling deeper reach into neighborhoods and a simplified path to network upgrades.
  • Extended Soft FDD – This new combination of software-only Frequency Division Duplex (FDD) and Extended Spectrum DOCSIS (ESD) – pushes network interface speeds beyond 1.2 GHz and is already being hailed as a preliminary flavor of DOCSIS 4.0. The advance comes just four months after the company first demonstrated soft FDD.
  • A new DOCSIS timing protocol – Precise timing distribution over the DOCSIS network is now possible. Such precision is imperative for time-critical processing and applications, where a fraction of a second means the difference between success and failure. Current and future applications include mobile backhaul, virtual reality, and autonomous vehicle control.

All will become elements of the company’s Distributed Access Architecture (DAA) and 10G portfolios.

CommScope will discuss and demonstrate the new technologies at the SCTE•ISBE Cable-Tec Expo beginning September 30th in New Orleans.

“It’s no longer enough to have the fastest network,” said Tom Cloonan, CommScope chief technologist for network solutions in the company’s Office of the CTO. “2020 is about efficiency and simplicity. There will be significant changes to architectures over time, and it’s important to work with a company that has both industry-leading technology and the expertise to execute at any point in that transformation.”

CommScope Advances 10G Broadband Roadmap

CommScope announced several areas of progress on its 10G Broadband roadmap
  • A low-latency DOCSIS system deemed crucial to next-generation broadband performance. The company is demonstrating IP video running alongside traditional QAM video over an EPON channel at 10 Gbps. 
  • A software-configurable Frequency-Division Duplex (Soft FDD) system with the potential to deliver 10G speeds over traditional coaxial wiring. Soft FDD uses FDX technology and provides a foundation for symmetrical services.
  • The E6000 vCore fully virtualized converged cable access platform (CCAP) core. This offers automated provisioning and capacity tools for end-to-end service provisioning and smart capacity additions; and orchestration and intelligence tools to manage multi-access configurations and produce better analytics about network performance.
CommScope notes that these announcements come fewer than six months after it revealed its role in pioneering the core technologies for 10 Gbps broadband (10G), and just four months after it announced a 8.5 Gbps network trial with Virgin Media.

In addition, Vodafone Germany is underway with a nationwide upgrade to support 1Gbps service. Some 12 million customers will enjoy the high-speed Gigabit service through an ARRIS broadband device when the rollout is complete. Swiss provider Sasag last month became the first European operator to announce upgrading its entire network to use DOCSIS 3.1 (D3.1) for both the upstream and downstream channels.
CommScope completed its acquisition of ARRIS International in April.

3M intros Expanded Beam Ferrule and Connector System

Earlier this month, 3M introduced an Expanded Beam Optical Connector System for single mode and multimode interconnects in next-gen data centers.

“We’ve reimagined fiber optic connectors,” said Nick Stacey, Ph.D., global laboratory manager at 3M. “Our ferrule and connector technology is designed to reduce cleaning requirements, to provide design flexibility and to enable the performance necessary for next-generation optical deployment.”

The 3M Expanded Beam Optical Ferrule uses a non-contact optical coupling in contrast to the more traditional physical contact methods. Together with the connector design, this helps to provide reduced sensitivity to dust, helping maintain signal integrity, and reducing the need for, and cost of, maintenance and cleaning.

It is available in single mode (1310 nm) and multimode (850 nm) versions. In single mode, insertion loss specification is <0 .70="" and="" db="" is="" loss="" return="">55 dB. In multimode, insertion loss specification is <0 .30="" and="" db="" is="" loss="" return="">25 dB. The configurable and scalable connector design can accommodate anywhere from 12 fibers to 192 fibers. The simple, but robust hermaphroditic component geometry design, with low part count, can be mated and re-mated reliably with a simple LC-style latch. The performance enables architects and engineers to deploy the technology in multilink data center applications.

HUBER+SUHNER debuts cross-connect fiber management system

HUBER+SUHNER introduced its LISA Double Access solution -- a high-density, modular cross-connect fiber management system solution that provides a maximum of 3600 ports per rack. Alongside the LISA Double Access is the IANOS fiber management system, which provides flexibility for managing high volumes of cables and data rates.

“We realise that the LISA Double Access has long been the technology of choice and is an important aspect of network design for our customers,” said Eduardo Lopes, Head of Product Management Fiber Management Systems (FMS) at HUBER+SUHNER.“ As pioneers in cost-effective cross-connect connectivity solutions, we are convinced that the use of a comprehensive, but simply structured fiber optic management system is crucial for the successful operation of a data center due to the vulnerability of fiber optic cabling.”

Also joining HUBER+SUHNER’s line-up at ECOC 2019, is its novel Wavelength Division Multiplexer Coupling Module (WCM) for chip on-board low-cost transceivers assemblies. Featuring between two and eight lambdas based on TFF filters and CUBO’s direct beam bouncing polymer optical bench technology, the WCM provides ultra-low loss performance to couple and (de)mux two-to-eight laser diodes or photo detectors from a PCB board into a fiber receptacle. It enables transceiver or optical board manufacturers to assemble the non-hermetic optical bench in a very low-cost passive way directly on top of the photo detectors or lasers integrated in their PCB board.

Adding to the extensive Fiber Connectivity range already presented, HUBER+SUHNER Cube Optics (CUBO) will also debut its new 400G PAM4 Receiver Optical Sub-Assembly (ROSA) at the event. Designed for use in 400GBase-FR transceivers, the four-channel demultiplexer – which contains four integrated photo detectors with linear transimpedance amplifiers – operates at 56GBaud lane speed and features an optical LC receptacle input and electrical flex foil output. The high sensitivity of -4.6dBm eliminates the need to use additional expensive and power-hungry DSP chips in the transceiver, while still meeting IEEE specifications.

Infinera's XR Optics delivers coherent optical subcarrier aggregation

Infinera introduced a point-to-multipoint coherent optical subcarrier aggregation technology with the potential to significantly reduce the number of transceivers required in an access network while eliminating intermediate aggregation.

Infinera's XR optics technology, which is optimized for hub-and-spoke traffic patterns, is powered by independently routable Nyquist subcarriers and coherent optical aggregation capabilities. With coherent subcarrier aggregation (CSA) capabilities, XR optics technology enables a single high-speed transceiver to simultaneously send and receive independent data streams to/from numerous low-speed transceivers.



Subcarriers can be flexibly sized. For example, 4 X 25G subcarriers defined in a 100G QSFP-28 transcrivers; or 16 X 25G subcarriers defined in a 400G QSFP-DD transceiver.

The company says that by leveraging these capabilities, network operators will be positioned to significantly reduce the number of transceivers in the network, eliminate the need for costly intermediate aggregation devices, and more efficiently optimize transport infrastructure for hub-and-spoke end-user traffic flows.

Initial areas of focus include DAA fiber deep networks, 5G X-haul, DSL/PON backhaul, and fiber-enabled business services.

XR optics is designed to be integrated into a variety of form factors, including industry-standard pluggables, from low-speed interfaces with a single subcarrier to high-speed (400G+) interfaces with numerous subcarriers.

“We’re excited to introduce the revolutionary concept of coherent subcarrier aggregation, one that will redefine the cost structure of next-generation transport networks,” said Dr. Dave Welch, Founder and Chief Innovation Officer. “XR optics addresses a fundamental deficiency in optical communications technology and is expected to have a significant impact on any network that implements an aggregation function.”

“Developing 400ZR solutions demands a large investment, and companies are looking for ways to leverage these investments by broadening their addressable market. Infinera has gone a step further in a big, bold move: it is combining its unique expertise in photonics, silicon, and network
management to yet again create a truly differentiated approach to solve the engineering challenges faced by network operators,” said Andrew Schmitt, Directing Analyst, Cignal AI.

“We are excited about XR optics and its potential to make optical networks more efficient,” said Beck Mason, SVP and General Manager Telecom Transmission, Lumentum. “Our market leading coherent transmission products, based on high-performance indium phosphide photonic integrated circuits, are well proven and deployed in volume in coherent transmission applications, including those employing digital subcarriers, the innovative technology upon which XR optics is based.”

“Optical aggregation with XR optics is a compelling new architecture for aggregating edge nodes such as 5G radios into high-speed 400G router ports without requiring active aggregation devices in the field. We welcome this multi-vendor effort to fundamentally reduce the complexity
and operational cost of aggregation networks,” said Christophe Metivier, VP of Manufacturing and Platform Engineering, Arista Networks.

ECOC 2019 -- a panel discussion, “XR Optics: Point-to-Multipoint Coherent Connectivity and the Future of Transport Network Architectures,” is scheduled for Wednesday, September 25 at 10:30 a.m. in Room Dodder B.
