Ethernet Ring Protection Switching is an effort at ITU-T under G.8032 Recommendation to provide sub-50ms protection and recovery switching for Ethernet traffic in a ring topology and at the same time ensuring that there are no loops formed at the Ethernet layer.
NETGEAR 5-Port Gigabit Ethernet Unmanaged Essentials Switch (GS305) - Home Network Hub, Office Ethernet Splitter, Plug-and-Play, Silent Operation, Desktop or Wall Mount.

Furthermore, visual representations like the one above help us fully grasp the concept of Wire Network Protection Switch.
Wiring a Smart Switch with an Ordinary Switch for 3-Way Lighting Circuit. Adding to the Network and App.Wiring a Smart Switch in a Smart Load Center Neutral Required. The following wiring diagram shows a 15A 120V smart Wi-Fi switch is used to control the lighting point.

Wired/Wireless Networking. On basis of physical medium, there are 2 types of networks: (a) Wired Network: As we all know, "wired" refers to any physical medium made up of cables. Copper wire, twisted pair, or fiber optic cables are all options.

Moving forward, it's essential to keep these visual contexts in mind when discussing Wire Network Protection Switch.
GPON is an alternative to Ethernet switching in campus networking. GPON replaces the traditional three-tier Ethernet design with a two-tier optic network which eliminates access and distribution Ethernet switches with passive optical devices.
