Webinar: Exploring PAM4 SR data center interconnects

Join us on Sep 15, 2021 10:00 AM in Pacific Time

Many standards use Pulse-Amplitude Modulation 4-Level (PAM4) Short Reach coding scheme, including for 200 Gbps and 400 Gbps interfaces within the data center. Some vendors have implemented DSP in their optical devices to handle noise impairments. To reduce cost and power consumption, others have developed PAM4 AOC (active optical cables) and SR modules using analog CDR technology. With the transition to 400G Ethernet in full swing, and 800G around the corner, unique challenges are presented which will be discussed during this webinar.

This 60-minute webinar will explore PAM4 interconnect approaches. We will hear from Dr. Yung Son, Chief Technology Officer and Chief Marketing Officer at Optomind, which offers an advanced optical engine technology for enabling 400G QSFP56-DD AOC and SR8 optical transceivers with analog CDR. We will also hear from Kees Propstra, Vice President of Marketing at MultiLane, a leading provider of High-Speed IO and Data Center Interconnect test solutions. Kees has a Master of Science in physics and a post-graduate degree in modern optics from the University of Twente, the Netherlands.

Spectra7 and MultiLane demo 112Gbps PAM4 Active Copper Cable

Spectra7 Microsystems and MultiLane will be demonstrating Spectra7's new 112G PAM4 GaugeChanger chip intended for next generation 800Gbps data center interconnects at this year's annual China International Optoelectronic Expo (CIOE) 2021 show at the Shenzhen Convention & Exhibition Center in Shenzhen from September 16-18.

As the industry moves to 800Gbps it will adopt 112Gbps PAM4 per lane signaling over 8 lanes. At these ultra-high signal rates, traditional passive copper cables will struggle to reach beyond 1.5 meters. This creates a huge problem for Hyperscalers that require longer lengths to serve both switch-to-switch and switch-to-server connections, but do not want to incur the power and cost penalty of optics. 

ACCs enabled with Spectra7's GC1122 solution will extend copper cable reach 2.5 times, up to 4 meters at a fraction of the cost of optics while consuming only 200mW of power per channel, which is up to 12 times lower power than optical solutions.

The GC1122 is the latest addition to Spectra7's GaugeChanger product line and extends the data rate from 56Gbps PAM4 to 112Gbps PAM4 per lane. Since the GC1122 is analog and highly linear, dynamics such as line rate adjustment, multi-level signaling, intermittent line silence, transmit pre-emphasis or amplitude adjustment and receiver adaptivity are fully preserved. The GC1122 is packaged in an ultra-small 2.7mm x 4.2mm chip scale package making it easily embeddable in even the smallest of connectors.

The CIOE demonstration highlights Spectra7's new GC1122 device as well as MultiLane's latest high speed test equipment including the ML4015D DSO and the ML4079E 800G BERT.

"Spectra7's new GC1122 is set to fill a big need in the data center interconnect market," said MultiLane CEO Fadi Daou. "We are delighted to be working with Spectra7 and their cable partners as they anticipate bringing their 112Gbps products to mass production in 2022."

"We are seeing tremendous interest from every Hyperscaler to get sample 800Gbps cables that are enabled by our new GC1122 solution", said Spectra7 CEO Raouf Halim. "Both we and our cable partners believe that 800Gbps will represent a significant acceleration in the growth and adoption of our ACC data center interconnect technology."

Juniper enhances its AI-driven enterprise portfolio

Juniper Networks announced enhancements to the Juniper Mist cloud and AI engine, which include EVPN-VXLAN campus fabric management and additional Marvis Actions for proactive problem remediation. The new features within the AI-driven enterprise portfolio that enable customers to scale and simplify the rollout of their campus wired and wireless networks while bringing greater insight and automation to network operators.

The latest additions to Juniper’s AI-driven enterprise include:

AI-driven campus fabric management via the Juniper Mist Cloud: By enabling EVPN-VXLAN campus fabric management via the Juniper Mist Wired Assurance cloud service, Juniper offers the ability to simplify wired, wireless and WAN via a common cloud and AIOps engine. Juniper EVPN-VXLAN fabric leverages the same Juniper platform used to manage wired access in the campus, Juniper Mist Wired Assurance and the Marvis Virtual Network Assistant (VNA), bringing IT administrators unparalleled automation, insight and troubleshooting. The Juniper Mist Cloud empowers administrators to choose a topology, define networks of interest, identify required physical connections and apply the correct underlying policies in a seamless fashion. In addition, the Juniper Mist solution enables customers to leverage a common operational schema across LAN, WLAN and WAN environments, a key part of the Juniper client-to-cloud differentiation.

New Marvis Actions that provide deeper insight for faster problem remediation: Marvis Actions takes insight derived from the Mist AI engine, such as the root cause of a problem, and delivers actionable recommendations for IT managers via a simple dashboard. Additional actions have been added to the Marvis VNA software subscription to detect and correct even more wired/wireless/WAN issues, such as persistently failing wired/wireless clients, bad cables, access point (AP) coverage holes, bad WAN links and insufficient RF capacity, among others.

“Juniper is committed to Experience-First Networking, where our enterprise solutions leverage proactive automation, assured user experiences, agile cloud services and connected security to deliver the best end-user and operator experiences from client-to-cloud,” said Jeff Aaron, Vice President of Enterprise Marketing at Juniper. “In the campus and branch, this means leveraging AIOps, driven by Mist AI and the cloud to maximize user productivity and efficiency while minimizing IT costs through simplified operations and prescriptive insights. Today, we are excited to accelerate in these areas – and further distance ourselves from the competition – with new enhancements to our Juniper Mist Wired Assurance, Wireless Assurance and Marvis Virtual Network Assistant (VNA) cloud services that make it even easier to deploy, operate and troubleshoot campus networks at scale.”

DISH picks IBM Global Business Services to automate its 5G architecture

DISH Network Corporation has engaged IBM Global Business Services to help automate its greenfield cloud-native 5G network. 

Specifically, DISH will leverage IBM's AI-powered automation and network orchestration software and services to bring broad 5G network orchestration to DISH's business and operations platforms. Intent-driven orchestration, a software-powered automation process, and artificial intelligence (AI) will be utilized to drive the operations of DISH's cloud-native 5G network architecture.

The IBM Cloud Pak for Network Automation software delivers intent-based orchestration functionality to stitch hardware and software resources. This will help DISH make network slicing possible and accelerate the creation and delivery of new services. Network slices – individual pieces that comprise said network – will be managed by customers to set service levels for each device appropriate to their use of the network. For example, an autonomous vehicle can be supported by very low latency while an HD video camera can be allocated high bandwidth. 

"Our 5G build is unique in that we are truly creating a 'network of networks,' where each enterprise can custom-tailor a network slice or group of slices to achieve their specific business needs. IBM's orchestration solutions leverage AI, automation and machine learning to not only make these slices possible, but to ensure they adapt over time as customer use evolves," said Marc Rouanne, chief network officer, DISH Wireless. "With IBM, DISH is combining the speed and latency advances of 5G with the customization and intelligence of the cloud, and the result will be a paradigm shift for small businesses, large enterprises and the broader wireless industry."

"This is a seminal moment for DISH and the global telecommunications industry," said Steve Canepa, managing director, IBM Global Communications Sector. "By utilizing IBM's AI-powered automation and intent-driven network orchestration software, DISH can develop and deploy network offerings, applying advanced AI with IBM Watson and orchestration capabilities to help optimize network operations and performance. As a result, DISH can accelerate time to market for new innovative services powered by a secured, automated, intelligent and agile 5G network."
