A significant milestone has been reached in the world of subsea connectivity, pushing the boundaries of data transmission speeds. A major operator recently shattered previous records on the Hawaiki subsea cable system, achieving an unprecedented 1.2 terabits per second (Tb/s) transmission speed per wavelength.
This remarkable feat was made possible through the deployment of cutting-edge coherent optical technology. By leveraging advanced chipsets and sophisticated modulation techniques, the capacity and spectral efficiency of the existing cable infrastructure were dramatically enhanced.
The implications of this achievement are substantial. Reaching speeds of 1.2 Tb/s per wavelength translates directly into a massive boost in the overall capacity available on the Hawaiki cable. This increased capacity is crucial for meeting the ever-growing demand for data, driven by cloud computing, video streaming, artificial intelligence, and various other digital services across the Pacific region.
Such advancements in optical networking technology are vital for ensuring future-proof connectivity. They allow network operators to extract more value and performance from their existing subsea assets, deferring the need for costly new cable builds while significantly increasing bandwidth availability for businesses and consumers alike across multiple countries. This high-capacity upgrade reinforces the cable’s position as a critical piece of digital infrastructure, supporting enhanced regional connectivity and digital transformation efforts. The successful trial demonstrates the potential for continued innovation to scale network performance and meet future data demands.
