The Future of Data Transfer Is Light
Fiber optics changed the world by allowing enormous amounts of information to travel as pulses of light through thin strands of glass.
But there is still a problem.
Even though today's networks use fiber-optic cables, data is often converted between optical and electrical signals as it travels through network equipment. Those conversions require equipment, create delays, and consume electricity.
Japan's NTT is working on taking the next step with IOWN — the Innovative Optical and Wireless Network.
NTT and Taiwan's Chunghwa Telecom have already established the world's first international All-Photonics Network between Japan and Taiwan. The approximately 3,000-kilometer connection provides a 100 Gbps optical path with one-way latency of about 17 milliseconds.
The important idea is simple:
Keep the data as light for as much of its journey as possible.
NTT's future goal for its All-Photonics Network is to achieve 100 times greater power efficiency. In theory, that represents roughly a 99% reduction in the power required for the same amount of work compared with the baseline.
Why does this matter?
AI and data centers are creating enormous demand for both bandwidth and electricity. We cannot simply keep building larger data centers and consuming more power forever.
We need to change how information moves.
For decades, we thought of computing as electronics connected by fiber optics.
The next generation may be different.
Light may not simply carry data between computers. It may increasingly become part of how computers and data centers communicate internally as well.
As the amount of data in the world continues to explode, I believe the future of large-scale data transfer is optical communication.
The future of networking may not be faster electricity.
It may be light.
