Green Marathon

By Vlad Kozlov, LightCounting | Posted: 3 March 2023

OFC in San Diego is always a marathon. More than 10,000 runners repeatedly traverse the quarter mile stretch of the exhibit floor over three days. This year it will be a green event, since the main focus will be improving the power efficiency of optical connectivity. Numerous demos will be sending photons across fiber cables and many of these photons will be generated and detected with a record high efficiency.

What is 100ZR and Why Does it Matter

By Harald Graber, Chief Commercial Officer, EFFECT Photonics | Posted: 13 February 2023

In June 2022, transceiver developer II‐VI Incorporated (now Coherent Corp.) and optical networking solutions provider ADVA announced the launch of the industry’s first 100ZR pluggable coherent transceiver. Discussions in the telecom sector about a future beyond 400G coherent technology have usually focused on 800G products, but there is increasing excitement about “downscaling” to 100G coherent products for certain applications in the network edge and business services. This article will discuss the market and technology forces that drive this change in discourse.

The growing and expanding PON market – a significant opportunity

By Julie Kunstler, Chief Analyst, Broadband Access Intelligence Service | Posted: 6 January 2023

CSPs (Communications Service Providers) and enterprises are deploying fiber access network infrastructure using passive optical network (PON)-based solutions, benefitting from PON’s many advantages, including fiber efficiency and energy savings. PON is easy to upgrade without requiring changes to the underlying ODN. Extensive 10G PON upgrades are underway, and “beyond 10G” implementations have begun. PON is the mainstream technology of choice for fiber-access networking across all regions.

OFC 2023 – The Drive to 3nm Will Push Innovation Limits and Drive Significant Announcements

By Alan Weckel, Founder and Technology Analyst, 650 Group (www.650group.com) | Posted: 5 December 2022

The entire data center and service provide (SP) industry are about to embark on their 3 nanometer (nm) design journey. The new designs will help drive a significant investment cycle by the data center and SP operators. The timing is good. OFC 2023 will see some of the most important product announcements since before the pandemic as vendors showcase what they have been working on behind closed doors for the past two years.

Reflections on the Pandemic, 5G and Optical Wireless

By Casimer DeCusatis | Posted: 2 February 2022

The COVID-19 pandemic continues to disrupt our work, education, and leisure activities, causing enormous loss of life and impacting the livelihood of millions around the globe. The pandemic has also brought long-standing issues of Internet access to the forefront, as everyone adjusts to video-based collaborative workplaces, distance education, remote healthcare, online commerce, and many other challenges. As we all grapple with pandemic related issues in our daily lives, in this blog we’ll take a look at some of the plans for the annual OFC meeting to address these concerns through special symposiums, workshops, and panel discussions.

Is quantum computing ready for prime time?

By Casimer DeCusatis | Posted: 20 December 2021

I’ve written about the state of quantum computing systems in previous OFC blogs, which has led some people to ask if I could put together a higher level introduction to the field for newcomers interested in the technology. As I was preparing this blog, I was reminded of the long, winding path that quantum computing has taken from its early inception in the 1960s to the prototype systems available today. In this blog, I’ll try to provide an overview of some basic quantum computing concepts, while also discussing the obstacles that remain before quantum computing becomes mainstream. We’ll need to make a few simplifying assumptions to get started, but since this is an introductory discussion we’ll skim over the more complex details and mathematics for now.

Emerging Innovations in Neuromorphic Computing

By Casimer DeCusatis | Posted: 28 October 2021

Research in photonic computing, particularly photonic integrated circuits, has been ongoing for some time; this includes recent applications in neuromorphic computing, the use of large-scale integrated hardware or software systems to mimic biological architectures in the human brain and nervous system. In this blog, we’ll take a quick look at some emerging innovations in this area.
