Although a PoE switch is a switch, it is actually a power supply device. If it is not for power supply, a common switch is usually selected. This kind of switch that can supply power not only has the transmission function of the ordinary switch, but also has the power supply function that the ordinary switch does not have.
It is its power supply function, PoE switch can easily solve the problem of many surveillance cameras to take power, so it has an advantage. Someone will ask how it can be powered? Does it have power inside? Actually, there is no power inside the PoE switch, only the PoE chip. Regarding how it supplies power, it is necessary to understand its principle.
The PoE switch has a PoE power supply chip. When it is connected to the surveillance camera via a network cable, it detects whether the camera supports PoE power supply. If it is supported, it will be further classified to determine how much power is needed. If the camera power is 10W, then provide 10W of power supply. Of course, if it is detected that the camera does not support PoE, then no power will be supplied and the natural camera will not work properly.
As can be seen from the above, the PoE switch must provide power to PoE-powered network devices. If the network device does not support PoE power supply but still wants to use the network cable, a PoE splitter must be added between them.
Having said this, everyone should clearly understand what PoE is. Next, the PoE switch with a PON port is mentioned. This switch has more PON ports than a normal PoE switch. The equipment with a PON port is generally used in a PON network, that is, a PoE switch with a PON port can. Applied to PON networks, while enjoying the advantages of PON networks, it also eliminates the need for additional power wiring.
A PON is a passive optical network. It consists of an ONU, an OLT, and an optical splitter. A single optical fiber is used between the ONU and the OLT. The optical splitter is a passive device that divides the optical fiber into multiple channels. At the end of the day, although PoE switches with PON ports are more PON ports, they are still PoE switches. They can also be understood as ONUs with PoE functions. It is understandable that PON networks can be used in PON networks.
Fengrunda EPS5081 is a device with 8 PoE ports and 1 PON port, also known as PON-PoE switch. The PoE port supports af/at power supply. The PON port provides a 1.25G transmission rate. With only one fiber connected to the OLT, the transmission distance can be easily extended to 20km.
In remote monitoring and large-scale campus monitoring, PoE switches with PON ports can be applied to PON networks, which not only solves the bandwidth and distance bottlenecks of traditional optical fiber transmission, but also solves the problem of front-end camera power supply. It can be said that the PoE switch with PON port combines PON technology with PoE technology and applies it to the monitoring field together, which promotes the development of China's surveillance industry. 
What is the difference between PoE switches and PoE switches with PON ports?
With the increasing demand for network monitoring, a variety of monitoring devices emerge in an endless stream. These devices are all designed to provide higher monitoring effects. We are not unfamiliar with the PoE switch, or it doesn't matter if you just started to contact. It will be clear after reading the following introduction.
