Key Questions Answered
What is the design capacity of the Pacific Light Cable Network?
The Pacific Light Cable Network (PLCN) has an initial estimated design capacity of 120 Tbps, making it one of the highest-capacity trans-Pacific systems. This capacity is crucial for supporting the increasing number of users on Facebook apps and services in the region.
How does PLCN differ from traditional subsea cable systems?
PLCN allows for independence between the wet plant and optical technology, enabling parties to select their optical equipment independently. This flexibility means that as optical technology advances, equipment can be refreshed more quickly, potentially reducing costs and increasing bandwidth rates.
What are the benefits of the direct route between Los Angeles and Hong Kong?
The direct route of PLCN provides more diversity and resiliency compared to traditional Pacific subsea cables that typically connect the U.S. to Japan. This new connection will enhance the overall network infrastructure and improve connectivity between Asia and U.S. data centers.
