"Ideas do not always come in a flash but by diligent trial-and-error experiments that take time and thought”

“Ideas do not always come in a flash but by diligent trial-and-error experiments that take time and thought”

Sir Charles Kao
4 November 1933 – 23 September 2018
Nobel Prize in Physics (2009)


We still have a lot to learn from Sir Charles Kao, the physicist termed the ‘father of fibreoptics’, the Nobel Prize winner, the inspiration behind our name at Kao Data (and latterly turned into a Google Doodle) who would have celebrated his 89th birthday today (4th November).

It was important to me when choosing a name that it reflected the endeavour and enterprise that building something new involves. Like the breakthroughs achieved by Sir Charles – it takes time, there are setbacks, but it is worth it in the end.

The impact of his 1960s breakthrough paper concerning the transmission of light in fibres for optical communication cannot be underestimated. It continues to enable much of the digital infrastructure that society needs to enable commerce, research, hybrid working, remote learning and creative collaboration across all industries.

His lifework was the bedrock on which we built Kao Data; fulfilling our vision to develop and operate advanced data centres with 100% renewable energy for high performance colocation with our Harlow HQ on the site where Sir Charles’s discovery was made.

In memory of him, here are three ways his intelligence, drive and impact continue to lead us all.

Creating a legacy beyond our own success

In his 1966 paper with co-author George Hockham, Kao unveiled the performance characteristics and design parameters necessary to underpin a successful fibreoptic network. Predictably, for that time, plenty of early naysayers piped up, quick to criticise.

“If you really look at it, I was trying to sell a dream … There was very little I could put in concrete to tell these people it was really real” he once said.

Undeterred, Kao went about spectrophotometric experiments to prove the existence of silicon dioxides with attenuation low enough for his discovery to work. It was only a matter of time until the scientific community problem-solved optical fibres of the required dimensions and strength – and here they are, in use throughout the world.

The successful mass adoption of fibreoptic began with the tremendous change Kao achieved and his unrelenting spirit of innovation and tenacity. This mirrors the team I am privileged to be part of at Kao Data, from the shareholders to the security guards, all looking to deliver the Kao Data vision, and to dream the next dream.


Lifelong learning and enabling others

Kao collaborated with many visionary innovators throughout his life with results that speak for themselves. He benefitted from a diverse early life in Chinese and Western education and worked worldwide in the private sector and in academia – returning to Chinese University (CUHK) before retiring.

“When you are young, you are fervent about the things you believe in,” he has said.

The Kao Academy, launched in May 2022 by Kao Data in association with Cambridge Science Centre, an independent, educational charity, that has proven to be another opportunity to celebrate Sir Charles’s legacy. It is an industry-first science, technology, engineering, and math (STEM) resource, designed to engage children with the purpose and role of data centres. We have seen amazing engagement from budding engineers giving us a glimpse of what the future in the industry holds.

We will never succeed unless we all succeed

Kao’s discovery remains the foundation of our growing global digital infrastructure and data centre industries. I can’t help but imagine the contributions he could make to our efforts to create responsible, reliable and resilient networks and storage today.

He has helped to create the digital, hyper-connected world we all now take for granted. I should think that our climate emergency, economic headwinds and global supply chain fragilities would cause Kao concern, but in his accomplishments, we can find cause for optimism.

Fibreoptic medical device manufacturing times are reducing. UK Power Networks will conduct the first trial of fibreoptic temperature sensing technology. Thanks to Kao, broadband networks continue to reach parts of the world in crucial need of connectivity and communication.

‘We will never succeed unless we all succeed,’ is a mantra jointly embraced by Goldacre and Kao Data. We are committed to building on Sir Charles’s pioneering legacy and – where our investments, teams and tech can drive change – ensuring it benefits people and planet for generations to come.
