About this webinar

The webinar will bring together key companies that are influencing the direction of the technology, products, and manufacturing.  The goal is to review what is hot and topical today but also with a view on the next 5-10 years as enablers to maintain competitiveness in the segment. Included will be perspectives on standards/MSA as well as the market environment.

Already, we are seeing key metrics such as high volume, integration, low power consumption, high speed, electronic enhancement and support of photonics (coding, FEC, dispersion, timing etc) with DSPs to name a few; become important to all stakeholders up and down the value chain of the industry.  Further, as everything advances as we would expect, the make-up and nature of the industry will evolve quickly and these webinars will review not only the technology perspective but also how the industry can meet future challenges and opportunities over the next decade.

We will complete the webinar with a panel session of the speakers and provide thoughtful questions by the moderator/session chair on issues both today and in the near future.

Stéphane Téral, Chief Analyst, LightCounting Market Research
With 31 years of experience in the telecommunications industry, including 23 years in Silicon Valley, Stéphane is regarded as one of the top analysts in his field, having been the trusted advisor at some of the world’s largest telecom providers and manufacturers. He specializes in next-generation mobile infrastructure including 5G, cloud and quantum networking, programmable core networks, and service provider digital transformation. He also tracks overall telecom economics and forecasts service provider capex, opex and revenue, as well as outsourced and managed services.

As an advisor to startups, service providers, vendors, and the investment community, he helps clients identify new market opportunities, as well as provides due diligence and advises on positioning, product development, business plans, and M&A activity. A highly sought thinker and speaker, Mr. Téralis quoted in prestigious publications such as The Economist, Le Monde, Les Echos, L’Usine Nouvelle, Barron’s, and The Wall Street Journal, and chairs and presents at events worldwide, including Carrier Network Virtualization, Brooklyn 5G Summit, 5G World and Self Organizing Networks World and Telco AI Summit. He has been a frequent expert judge for industry and technology innovation awards, such as the GSMA Mobile World Congress, Telco AI Summit, and 5G World.

In 2006, he joined Infonetics Research, now IHS Markit/Informa Tech. Previously, he was with analyst firm RHK, where he developed their European optical coverage and helped carriers migrate from PSTN to next-generation networks. Prior to RHK, he was an R&D engineer and project manager with Alcatel, where he deployed the CATV optical networks that allowed the 1992 Olympics and the grand opening of Euro Disney to be televised using fiber optics for the first time. Stéphane Téral was a McGowan Scholar at the McLaren School of Business, University of San Francisco, United States, where he received his MBA, and has an engineering degree in telecommunications from Télécom Sud Paris now known as the Institut Polytechnique de Paris, France.

Presentation summary

BT – Andrew Lord, Senior Manager of Optical Research at BT
5G is already happening, but we all hope that the technology will form the bedrock for exciting new applications, requiring more than just high bandwidth. My talk will compare optical transport solutions for macro and micro cells including optical point-multi-point architectures like WDM PON or the new XR technology. I will also describe integration with future edge data center functions. I will show how a dynamic end-to-end control plane will be essential. Finally I will discuss the potential impact of newly developed Hollow Core Fibre to ease latency requirements.

LightCounting Market Research – Stéphane Téral, Chief Analyst
This presentation will look at the implications of 5G on transport networks and particularly why fiber is becoming more important. It will cover 3GPP splits leading to fronthaul and mid-haul; open RAN, vRAN and open vRAN; emerging technologies such as integrated access backhaul (IAB), which was standardized in 3GPP’s Release 16 as well as developing trends in disaggregation from cell site gateways and routers all the way to core routers.

Yamaichi Electronics Deutschland GmbH – David Binder, Business Development Manager Data Networking
In the global 5G rollout, both technical and geopolitical factors apply. A 5G front-end unit may have a different hardware spec in China than in the EU. Narrowed down to the pluggable I/O transceiver interface we expect SFP(x) to dominate in the EU, and NGSFP in China. Yamaichi Electronics developed a “one fits all” pluggable I/O host connector, complying with SFP(x), DSFP and NGSFP – aiming to seize the combined quantity potential of the Chinese and European roll out. In this webinar, we would like to introduce our host connector, which is backwards compatible, cross-compliant and future ready up to 112G-PAM4/Ch

As more 5G spectrum is being unlocked and the number of live networks globally are well above 100, it’s critical to focus on the right optical solutions and the right time and cost for the evolving radio access networks and accompanying transport systems.  This talk will outline the key requirements and some of the most important deployment use cases, called mobile optical blueprints, with the optical pluggables as the key building blocks. The case is made that this approach allows the industry to better focus its efforts.
