Ayar Labs gets to work with leading AI and HPC vendors

Optical interconnect specialist Ayar Labs has announced that it is working with Nvidia, a leader in artificial intelligence (AI) and machine learning silicon, systems and software.

In February Ayar Labs announced a strategic collaboration with the world’s leading high-performance computing (HPC) firm, Hewlett Packard Enterprise (HPE).

Both Nvidia and HPE were part of the Series C funding worth $130 million that Ayar Labs secured in April.

The various paths to co-packaged optics

Near package optics has emerged as companies have encountered the complexities of co-packaged optics. It should not be viewed as an alternative to co-packaged optics but rather a pragmatic approach for its implementation.

Co-packaged optics will be one of several hot topics at the upcoming OFC show in March.

Placing optics next to silicon is seen as the only way to meet the future input-output (I/O) requirements of ICs such as Ethernet switches and high-end processors.

For now, pluggable optics do the job of routing traffic between Ethernet switch chips in the data centre. The pluggable modules sit on the switch platform’s front panel at the edge of the printed circuit board (PCB) hosting the switch chip.

But with switch silicon capacity doubling every two years, engineers are being challenged to get data into and out of the chip while ensuring power consumption does not rise.

ECOC 2019 industry reflections

Gazettabyte is asking industry figures for their thoughts after attending the recent ECOC show, held in Dublin. In particular, what developments and trends they noted, what they learned and what, if anything, surprised them. Here are the first responses from Huawei, OFS Fitel and ADVA.  

James Wangyin, senior product expert, access and transmission product line at Huawei  

At ECOC, one technology that is becoming a hot topic is machine learning. There is much work going on to model devices and perform optimisation at the system level.

And while there was much discussion about 400-gigabit and 800-gigabit coherent optical transmissions, 200-gigabit will continue to be the mainstream speed for the coming three-to-five years.
