What architecture was developed to provide a cost-effective, high-bandwidth solution for public internet connectivity?

The architecture that was developed to provide a cost-effective, high-bandwidth solution for public internet connectivity is the Gigabit Capable Passive Optical Network (GPON). GPON technology allows for a significant amount of data to be transmitted over a single optical fiber, making it suitable for delivering high-speed internet services efficiently.

GPON supports high capacity through its ability to deliver broadband services to multiple users via passive optical splitters, which direct the optical signal to multiple endpoints without the need for active electronic components. This reduces infrastructure costs while increasing bandwidth, addressing the growing demand for high-speed internet access in public and residential sectors.

While Broadband PON (BPON) and Asynchronous Passive Optical Network (APON) are also PON technologies, they do not have the same capacity or efficiency as GPON. BPON primarily supports lower-speed services, and APON was one of the earlier versions that preceded GPON without the enhancements that come with newer technologies. Wireless Optical Networks (WON) offer a different approach and do not primarily focus on wired internet connectivity solutions.

In summary, GPON is recognized for its ability to deliver efficient, high-bandwidth internet connectivity in a cost-effective manner, making it the correct choice in this context.
