Power-over-Ethernet (PoE) Switch is a type of network switch that has the ability to supply power to specific devices. Depending on the method, there are two main types of PoE switches: active PoE and passive PoE. An Ethernet cable has eight signal lines, four of which are used for data transmission and the other four for DC power supply.

A ring network is a in which each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node – a ring. Rings can be unidirectional, with all traffic travelling either clockwise or counterclockwise around the ring, or bidirectional (as in ). The fiber optic ring redundancy design for industrial Ethernet switches is precisely engineered to address this pain point—achieving millisecond-level fault self-healing through the synergy of physical ring architecture and intelligent protocols, thereby constructing the "self-healing heart" of. Due to that, an innovative idea of forming PON with a simple ring topology b using standard passive splitters was proposed and is presented within this paper.
