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.

A coherent roadmap for co-packaged optics

Is coherent optics how co-packaged will continue to scale? Pilot Photonics certainly thinks so.

Part 1: Co-packaged optics 

Frank Smyth

Frank Smyth, CTO and founder of Pilot Photonics, believes the firm is at an important inflection point. 

Known for its comb laser technology, Pilot Photonics has just been awarded a €2.5 million European Innovation Council grant to develop its light-source technology for co-packaged optics. 

The Irish start-up is also moving to much larger premises and is on a recruitment drive. “Many of our projects and technologies are maturing,” says Smyth.

First co-packaged optics switches set for next year 

Ranovus says two of its lead customers will deploy co-packaged optics next year.

They will deploy 25.6-terabit Ethernet switch chips but these will be proof-of-concept designs rather than volume deployments.

Hamid ArabzadehThe deployments will be used to assess the software and gain experience with their maintenance including replacing optics if needed.

“I do think 2024 is going to be the volume year,” says Hamid Arabzadeh, CEO of Ranovus, who expects to announce the customers before the year-end.

Ranovus outlines its co-packaged optics plans 

Part 2: Odin technology

Ranovus has tested a chiplet that combines electronics and silicon photonics. Dubbed Odin 8, the monolithic design is targetting the co-packaged optics opportunity, enabling silicon chips to communicate optically.

The company is developing two such chiplets: the 800-gigabit Odin 8 and the higher-capacity Odin 32 that supports 3.2 terabits of traffic. 

Hamid Arabzadeh 

The first use of Odin 8 will be for 800-gigabit client-side modules. We already have three lead customers for our 800-gigabit module business,” says Hamid Arabzadeh, CEO of Ranovus.

The 800-gigabit pluggable modules using the Odin 8 are expected to be generally available from late 2021.

Coherent optics players target the network edge for growth

Part 1: Coherent developments

The market for optical links for reaches between 10km and 120km is emerging as a fierce battleground between proponents of coherent and direct-detection technologies. 

Interest in higher data rates such as 400 gigabits is pushing coherent-based optical transmission from its traditional long-distance berth to shorter-reach applications. “That tends to be where the growth for coherent has come from as it has migrated from long-haul to metro,” says Tom Williams, senior director of marketing at Acacia Communications, a coherent technology supplier.

Williams points to the Optical Internetworking Forum’s (OIF) ongoing work to develop a 400-gigabit link for data centre interconnect. Dubbed 400ZR, the project is specifying an interoperable coherent interface that will support dense wavelength-division multiplexing (DWDM) links for distances of at least 80km.

Reflections on OFC 2017

Mood, technologies, notable announcements - just what are the metrics to judge the OFC 2017 show held in Los Angeles last week?

It was the first show I had attended in several years and the most obvious changes were how natural the presence of the internet content providers now is alongside the telecom operators, as well as systems vendors exhibiting at the show. Chip companies, while also present, were fewer than before.

Another impression were the latest buzz terms: 5G, the Internet of Things and virtual reality-augmented reality. Certain of these technologies are more concrete than others, but their repeated mention suggests a consensus that the topics are real enough to impact optical components and networking.

Ranovus shows 200 gigabit direct detection at ECOC

Ranovus has announced it first direct-detection optical products for applications including data centre interconnect.


Saeid AramidehThe start-up has announced two products to coincide with this week’s ECOC show being held in Dusseldorf, Germany.

One product is a 200 gigabit-per-second (Gbps) dense wavelength-division multiplexing (WDM) CFP2 pluggable optical module that spans distances up to 130km. Ranovus will also sell the 200Gbps transmitter and receiver optical engines that can be integrated by vendors onto a host line card. 

The dense WDM direct-detection solution from Ranovus is being positioned as a cheaper, lower-power alternative to coherent optics used for high-capacity metro and long-haul optical transport. Using such technology, service providers can link their data centre buildings distributed across a metro area.
