Which fiber equipment is functionally similar to a core/distribution router in a PON network?

In a PON, the device that manages and aggregates traffic from many subscribers and ties into the core network is the Optical Line Terminal. It sits at the service provider’s side and handles downstream broadcast, upstream scheduling, QoS, encryption, and multiplexing of multiple ONTs over a single fiber link through passive splitters. This centralized control and capability to route/forward traffic toward and from the core mirror what a core or distribution router does in traditional networks. The subscriber-side device, the ONT, terminates the PON at the customer premises and provides the interface to end-user devices; it doesn’t perform the routing decisions for the provider’s network. A UTP switch is a copper Ethernet device for LANs and isn’t the backbone equipment in a fiber PON. A hub is an obsolete device that simply repeats signals and does not provide proper routing or QoS for the network.
