Nubis' bandwidth-packed tiny optical engine

• Nubis Communications has revealed its ambitions to be an optical input-output (I/O) solutions provider
• Its tiny 1.6-terabit optical engine measures 5mm x 7.5mm
• The optical engine has a power consumption of below 4 picojoule/bit (pJ/b) and a bandwidth density of 0.5 terabits per millimetre.
• “Future systems will be I/O with an ASIC dangling off it.”

Nubis Communications has ended its period of secrecy to unveil an optical engine targeted at systems with demanding data input-output requirements.

Dan HardingThe start-up claims its optical engine delivers unmatched bandwidth density measured in terabits per millimetre (T/mm) and power consumption performance metrics.

“In the timeframe of founding the company [in 2020], it became obvious that the solution space [for our product] was machine learning-artificial intelligence,” says Dan Harding, the CEO of Nubis.

OIF to double data rate with a 224G electrical interface

• The OIF will develop a faster electrical signalling standard 
• The 224-gigabit standard will make optical modules sleeker 
• It will also help data centre operators keep up with ever-growing software workloads

Nathan TracyIt was just a matter of time before the OIF started on the next electrical interface standard beyond 112 gigabits-per-second (Gbps).

There have been announcements of new 800-gigabit optical modules along with growing interest in co-packaged optics, where optical interfaces are added alongside semiconductor chips.

Nathan Tracy, TE Connectivity and OIF president, says member companies will need to be creative to develop a 224-gigabit electrical interface. Getting signals to travel at such speeds over workable distances will be a challenge.  

The project, to kick-off in August, will begin with a study phase that will help identify the interface types needed.
