OIF adds a short-reach design to its 1600ZR/ ZR+ portfolio

The OIF (Optical Internetworking Forum) has broadened its 1600-gigabit coherent optics specification work to include a third project, complementing the 1600ZR and 1600ZR+ initiatives.

Karl Gass

The latest project will add a short-reach 'coherent-lite' digital design to deliver a reach of 2km to 20km and possibly 40km with a low latency below 300ns.

The low latency will suit workloads and computing resources distributed across data centres.

"The coherent-lite is more than just the LR (long reach) work that we have done [at 400 gigabits and 800 gigabits]," says Karl Gass, optical vice chair of the OIF's physical link layer (PLL) working group, adding that the 1600-gigabit coherent-lite will be a distinct digital design.

I recently attended a Royal Society Discussion Meeting where Leslie Valiant gave a brilliant talk on educability as a better definition than intelligence. A Harvard professor, he has developed many algorithms that underpin today's networks, including Valiant's load balancing. He is a profound thinker, and I wanted immediately to read his book, The Importance of Being Educable: A New Theory of Human Uniqueness.'

AI’s next wave

The spectacular rise in the capabilities of artificial intelligence (AI) is directly attributable to the scaling of the computing hardware used to train AI models.

Nigel Toon

“People discovered early on that if you increase the size of those models and the amount of data to train those models, you get a big step-up in accuracy and performance,” says Nigel Toon, CEO and chairman of AI processor firm Graphcore. “The results have been stunning.”

Toon cites research that shows that for large language models the size of the model and the data must be scaled equally.

However, AI developers have started to see a slowdown in the gains achieved solely by such scaling. This is leading to new thinking in how engineers build an AI model and how it generates its output when prompted. The result is a new wave of AI, says Toon.

I spent the year enjoying a poem a day from Brian Bilston’s Days Like These: An Alternative Guide to the Year in 366 Poems.

You may have seen his poems on social media, as he’s sometimes called The Poet Laureate of Twitter. It’s been a joy to end the day with one of his hilarious, occasionally poignant, and always topical poems.

I love reading but have not read as many books as I would have liked in recent years. I decided to change that in 2024.

My pick of fictional books this year was mainly classic science fiction after seeing the movie Dune Part 2 with my family. I read the book Dune by Frank Herbert, published in 1965, a while ago, and I wasn't sure that the movies did the book justice.

Podcast: Is AI driving a new wave of photonic innovation?

AI is still in its infancy, but it’s already pushing the photonics and computing industries to rethink product roadmaps and drive new levels of innovation.

Adtran's Gareth Spence talks with authors and analysts Daryl Inniss and the editor of Gazettabyte about the fast pace of AI development and the changes needed to unlock its full potential. They also discuss the upcoming sequel to their book on silicon photonics and its focus on AI.
