ECOC 2024 industry reflections - Part II

Gazettabyte is asking industry figures for their thoughts after attending the recent 50th-anniversary ECOC show in Frankfurt. Here are contributions from Nubis Communications' Dan Harding, imec's Peter Ossieur, and Chris Cole.

Dan Harding, CEO, Nubis Communications

Our biggest takeaway from ECOC is the increased confidence not just in 200-gigabit electrical and optical interfaces but also in 400 gigabit. It is becoming clear that in 2025 and 2026, the industry will broadly launch platforms using a 200 gigabit per lane serdes [serialiser/deserialiser interfaces] that will connect to 200 gigabit per lane optics.

Users embrace OpenLight's silicon photonics platform

OpenLight, the open silicon photonics platform provider, can point to a successful 2024 signing up new customers. 

In 2023, OpenLight had three customers bringing photonic integrated circuit (PIC) designs to market. OpenLight has since added 14 more.  

OpenLight was formed in 2022 when Juniper Networks carved out its silicon photonics arm. Synopsys acquired a three-quarters stake in OpenLight, while Juniper retained a quarter.

“In the past, the company hadn’t really done any revenue, including when they were in Juniper,” says Adam Carter, OpenLight’s CEO (pictured). “We’ve seen a ten times increase and shown that we can be very profitable.”

The start-up has been creating industry partnerships to better serve its customers' circuit design, chip manufacturing, and packaging needs.

Ciena sends a 1.6T optical lambda over a 470km link

• Ciena details its first live trial result using its latest WaveLogic 6 Extreme coherent modem.
• The modem will be generally available at the end of the month.  

Ciena has detailed its newest coherent modem's first optical networking performance: sending 1.6 terabits of data over a 470km fibre link.   

Helen Xenos

The field trial used Ciena's WaveLogic 6 Extreme coherent modem in telecom operator Arelion's live network.

The link connects an Equinix data centre in Ashburn to a Telxius submarine cable landing station also in Virginia. 

"The fact that we are achieving 1.6-terabit wavelengths across close to 500 kilometres is a testament to the performance and integrity of the design," says Helen Xenos, senior director of portfolio marketing at Ciena.

Has the era of co-packaged optics finally arrived?

Part 3: Co-packaged optics: Ayar Labs CEO interview

Mark Wade, newly appointed CEO of Ayar Labs, shares what his new role entails and why, after a decade-long journey, co-packaged optics' time has come.

Ayar Labs' CEO, Mark Wade

Mark Wade, the recently appointed CEO of Ayar Labs, says his new role feels strangely familiar. Wade finds himself revisiting tasks he performed in the early days of the start-up that he helped co-found. 

“In the first two years, I would do external-facing stuff during the day and then start working on our chips from 5 PM to midnight,” says Wade, who until last year was the company’s chief technology officer (CTO).  

More practically, says Wade, he has spent much of the first months since becoming CEO living out of a suitcase and meeting with customers, investors, and shareholders.

OFC 2024 industry reflections: Final part

In the final part, Chris Cole, Ranovus' Hojjat Salemi, and Infinera's Harald Bock share their thoughts about the revent OFC show. 

Chris Cole, Consultant

OFC and optics were back with a vengeance. The high level of excitement and participation in the technical and exhibit programmes was fueled by artifical intelligence/ machine learning (AI/ML). To moderate this exuberance, a few reality checks are offered.

During the Optica Executive Forum, held on the Monday, one of the panels was with optics industry CEOs. They were asked if AI/ML is a bubble, and all five said no. They are right that there is a real, dramatic increase in optics demand driven by AI/ML, with solid projections showing exponential growth.

OFC 2024 industry reflections: Part 4

Gazettabyte is asking industry figures for their thoughts after attending the recent OFC show in San Diego. This penultimate part includes the thoughts of Cisco’s Ron Horan, Coherent’s Dr. Sanjai Parthasarathi, and Adtran’s Jörg-Peter Elbers.

Ron Horan, Vice President Product Management, Client Optics Group, Cisco   

Several years ago, no one could have predicted how extensive the network infrastructure required to support artificial intelligence (AI) and machine learning (ML) back-end networks in data centres would be. This year's OFC answered that question. In a word, immense.
