Amazon's satellite internet ``Project Kuiper'' successfully verified data communication technology using infrared lasers that is approximately 30% faster than terrestrial optical fiber cables
The satellite internet `` Project Kuiper '' being developed by Amazon uses prototype satellites to build an optical mesh network in low earth orbit, and has successfully demonstrated high-speed communication of 100 Gbps on the satellite internet.

Since launching two Project Kuiper prototype satellites in October 2023, Amazon has conducted extensive testing of end-to-end communications payloads and networks. In November, we will be demonstrating the Project Kuiper network by validating all priority systems and subsystems . One of the important systems in Project Kuiper is the optical intersatellite link (OISL) function.
Project Kuiper's prototype satellites, KuiperSat-1 and KuiperSat-2, contain advanced optical communications payloads. Amazon announced that it has successfully conducted multiple demonstrations using this optical communication payload. According to Amazon, the demonstration succeeded in maintaining a high-speed communication link of 100 Gbps over a distance of about 1000 km. Because the test demonstrated the final components of Project Kuiper's advanced communications architecture, we can expect OISL to work on Project Kuiper's production satellites, scheduled for launch in the first half of 2024.
'With OISL across Amazon's satellite fleet, Project Kuiper effectively operates as a mesh network in space,' said Rajeev Badial, Amazon's vice president of technology in charge of Project Kuiper. Completely designed in-house to optimize reliability, the entire architecture works perfectly from the start. These immediate results are the result of Amazon's fully integrated system design. This is a testament to our team's commitment to ingenuity and ingenuity for our customers, as we worked in part to develop the OISL architecture. We are confident that we will be able to support next-generation OISL capabilities on all Project Kuiper satellites from day one. I'm excited.''
OISL uses infrared lasers to enable data to be exchanged between satellites orbiting the planet. While existing satellite internet is limited to transmitting data between individual satellites and antennas on the ground, OISL allows satellites to transmit data directly to other satellites in
Another advantage of OISL is the speed at which data can be sent around the world. Because light can travel faster through space than through glass, Project Kuiper's satellite Internet can transfer data approximately 30% faster than Internet communication services provided through terrestrial fiber-optic cables. It becomes. Project Kuiper leverages AWS services and infrastructure to route data traffic, further reducing overall network latency.
OISL has been a long-standing challenge for broadband connectivity for low earth orbit (LEO) satellites. Establishing and maintaining a laser link requires ensuring a strong signal while minimizing light spread, establishing communications over distances of up to 2600km, and man-made objects traveling at speeds of up to 25,000km/h. It is necessary to maintain connections between satellites. All of the above must be achieved while compensating for satellite dynamics. With this test, Amazon has successfully designed a state-of-the-art optical and control system that can address these challenges.
'Amazon's optical mesh network provides multiple paths to route data through space, keeping information secure around the world,' said Ricky Freeman, vice president of Kuiper Government Solutions, a specialized division of Project Kuiper. This provides resiliency and redundancy for customers who need to transfer data from remote locations to desired destinations. We look forward to making these capabilities available to public sector customers looking to deliver their data.'
