It has been a while since my last blog, as I was busy preparing for and attending OFC. Afterward, I needed time to digest all the valuable insights I gathered. To be honest, getting started on this blog was daunting—I wasn’t sure which topic to address first, given the wealth of fascinating discussions at OFC. Unlike previous years, the focus wasn’t primarily on broadband; instead, AI connectivity took center stage, along with its vast bandwidth and low latency requirements.

The rapid advancement of Artificial Intelligence (AI) and Machine Learning (ML) is fundamentally reshaping datacenter network architectures. Presentations at the OFC Summit on Optics for AI Datacenters highlighted a clear trajectory driven by the insatiable demand for data. Three interconnected themes emerged: the sheer scale of future connectivity needs, the ongoing shift from traditional pluggable optics to Co-Packaged Optics (CPO), and the longer-term evolution towards highly integrated Optical I/O (OIO).

Distributed sensing at the access level of the FTTx network could have several benefits, such as notification when digging is done to close to the fiber, when there is tampering with the fiber, structural health of the cable or sensing of geological events (flooding, earth slide, etc…).
However, the cost of full-on distributed sensing is not cost effective, but there are a few alternatives, these techniques leverage standard or specialized optical equipment and analysis of light propagating through the fiber to detect physical changes. They generally offer lower initial cost than dedicated DS systems but may have limitations in spatial resolution or the type of information they provide.

This report summarizes key insights and trends from several OFC conference sessions, highlighting major shifts in network architecture, optical technologies, and strategic opportunities driven primarily by the demands of AI and escalating bandwidth requirements.

How are you seeing FTTx adapting to meet the demands of automation and digital equality? My latest blog examines how configuration flexibility and adaptability, especially the shift to direct distribution, is playing a crucial role

Is Your RAN Cable Infrastructure Ready to Unlock the Monetization Potential of AI? The other day I watched the webcast of Light Reading on The

Maximizing Space: How Reduced Cladding and Coating Fibers Improve Data Center Efficiency Just the other day, I was reminiscing about some exploits from the past.

In the first three parts of this blog series, we explored various critical aspects of IT cabling for AI clusters, emphasizing the impact of high bandwidth and latency requirements on connectivity solutions, the practical considerations of deployment and installation, and the sustainability implications of different cabling choices.

It has been a while to get part 3 going as I was emerged in the cabling architecture of the NVIDIA H100 and GB200 ultra large clusters and how this impacts the cabling product portfolio. And am glad to share some lessons from that here.
