Where does all the splitting take place in a local convergence for PON?

In a Passive Optical Network (PON), the splitting of the optical signal typically occurs at the Location of the Convergence Point (LCP). The LCP is crucial because it serves as the point where the optical signals are divided and distributed to multiple end users.

This division allows a single optical fiber to serve multiple endpoints, optimizing fiber resource utilization and reducing the amount of cabling required. The optical splitters, which are passive devices, are placed at the LCP to ensure that the signals are appropriately split without requiring any active components, which would increase complexity and cost.

In contrast, the other choices represent points in the network where splitting does not occur:

• The Central Office typically functions as the starting point for a PON but does not involve the splitting of signals for downstream distribution.

• The Distribution Point is used to manage connections and may house components like optical patches or splicing, but it is not primarily where the signal splitting happens.

• The Network Interface Device, which connects end users to the network, receives the signals after they have been split, but does not perform any splitting itself.

Therefore, recognizing that the LCP is specifically designed for signal distribution defines its role as the point of convergence where splitting occurs in a PON setup
