Composition and Structure of Passive Optical Networks
A passive optical network consists of an optical line terminal (OLT) at the service provider's central office (hub), passive (non-power-consuming) optical splitters, and a number of optical network units (ONUs) or optical network terminals (ONTs), which are near end users. A passive optical network (PON) is a fiber-optic telecommunications network that uses only unpowered devices to carry signals, as opposed to electronic equipment. In practice, PONs are typically used for the last mile between Internet service providers (ISP) and their customers. PON primarily utilizes a point-to-multipoint topology and fiber optical splitters to transmit data from a single point of transmission to multiple user. Passive Optical Network (PON) stands as a foundational technology in the evolution of modern telecommunications, serving as the cornerstone for high-speed fiber-optic networks.

Layer 3 switch connecting multiple networks
A Layer 3 switch (also called a multilayer switch) is a purpose-built hardware device that blends features of a traditional Layer 2 switch and a router. It plays a critical role in modern networks by performing high-speed packet forwarding while also making routing decisions at Layer. But at the same time, switches can connect devices within the same network, but they can't connect different IP networks, as shown in the diagram below. A switch operates within a single VLAN and broadcast domain, which matches one IP subnet., they don't forward data to destination based on L3 attributes like destination IP address. Many Cisco Meraki switches have L3 routing capability. These vlan interfaces are the default gateways for the vlan 2 and 3 respectively. This layer 3 core switch is connected to two other layer 2 switches: Layer 2 switch #1 Layer 2 switch #2 When a client on vlan 2 tries to communicate with a client on vlan 3 on switch #1, traffic has to travel through. Normally, Routers are used to divide the broadcast domain and switches (at layer 2) Operate in a single broadcast domain but Switches can also divide the broadcast domain by using the concept of VLAN (Virtual LAN).

Core switch connects to two external networks
Core switches form an integral part of this framework, ensuring efficient communication and data transfer between multiple networks. Often regarded as the backbone of a computer network, they serve as a high-capacity conduit for connecting lower-tier switches and various network devices. Network. Unlike access switches, which connect directly to end-user devices, the core switch focuses on aggregating and routing traffic between other switches, minimizing latency and maximizing throughput. Engineered to aggregate massive volumes of data from distribution switches, it provides ultra-low latency and maximum throughput to ensure uninterrupted routing and packet. It is a powerful backbone switch in the center of the network core layer, which centralizes multiple aggregation switches to the core and implements LAN routing. This is L3 connection between the core switches.
