To extend the PoE (Power over Ethernet) distance, we can take some effective methods to achieve it! This article will introduce you to some ways to extend the PoE (Power over Ethernet) distance.
Use PoE Extend mode:
Some PoE switches are equipped with "Extend mode". This means that the transmission distance can be extended to a certain extent, usually up to 200 meters. But enabling this mode may require certain trade-offs in performance.
Add PoE extenders:
PoE extenders can break the 100-meter transmission distance limit. Some PoE extenders can connect up to 4 devices at once. They extend the power and network data distance. This distance can reach between 200 meters and 500 meters.
Choose a PoE power supply module with fiber optic function:
PoE fiber optic power supply modules work well for large campuses, highways, and other places. They can transmit data over long distances, measured in kilometers. You can input data through the LAN port or the SFP fiber optic port. This allows for long-distance and stable data and power transmission.
Install a switch as a relay device:
Installing a switch between two twisted pair cables can extend the transmission distance. In theory, the transmission distance can be further increased by installing multiple switches. However, it is necessary to pay attention to the signal stability and the number of switches.
Reduce the data transmission rate:
In certain cases, by reducing the data transmission rate. This can extend the transmission distance of PoE power supply, but this method may sacrifice the data transmission rate.
Use a fiber optic transceiver:
For distances exceeding 300 meters, a fiber optic transceiver can be used for fiber optic transmission. Fiber optic transmission signals are smooth and stable, which is an ideal way for long-distance transmission.
Consider cable quality and laying:
Using low-impedance, high-quality network cables can support longer transmission distances. At the same time, when laying cables, the effect of cables on heat dissipation should be considered. The purpose of this is to avoid performance degradation due to channel attenuation and insertion loss.
In summary, there are several ways to extend the PoE distance. You can choose the best method based on your specific needs and situation.
