The role of PON-PoE switches in some monitoring projects

With the widespread use of PoE technology and the use of PON in the field of monitoring, PoE switches with PON ports are gradually becoming "born." For example, Feng Runda recently launched a power supply switch EPS5081 with eight PoE ports and one PON. Mainly in the field of monitoring, although the promotion of the market is very hot, but there are still many people do not know what the benefits of this kind of thing, the following simple to say personal opinions.

The rise of network monitoring has driven the development of PoE technology. Now more than 70% of monitoring systems use PoE power supply. The direct benefit of this power supply mode is that no additional power wiring is required. For example, a camera is installed, but there is no way to pull the cable in the place where the camera is installed. It is impossible to supply power to the camera. The conventional method is to move the position. PoE power is not needed to move the position.

Therefore, the existence and development of a technology always have its value, and PON is no exception. PON is a passive optical network system. It was previously used in the broadband field, such as telecommunications, China Unicom, and other operators. Such networks are used to provide high bandwidth. Today's network monitoring gradually begins to use PON access methods due to the requirements of network bandwidth and distance.

Regression theme, PON-PoE switch is actually an ONU with PoE technology, which is a kind of PON network access equipment that can supply power. In fact, we can see at this time, the role of PON-PoE switch is: to provide high-bandwidth and long-distance data transmission, you can also avoid the extra power wiring.

The optical network uses PoE networking. Although the power supply problem is solved, the provided bandwidth is wired and data cannot be transmitted over a long distance. In the optical PON networking mode, the ONU cannot supply power, and it also requires additional power supply to the front-end camera. Therefore, PON-PoE switches can solve these problems. Its benefits are also these.
