2. Application Diagram
PLANET Long Reach PoE solution is designed to extend IP Ethernet
transmission and inject power simultaneously into a remote 802.3af/at PoE
compliant powered device (PD) beyond the 100 meters distance limit of
Ethernet. The solution works in pairs for point to point and point to multipoint
connectivity.
The LRP-104CET supports two ways as power source to inject 802.3af/at PoE
to remote standard PDs (Powered Devices).
z
Remote LRP Power from LRP Injector/switch over coaxial cable
z
Local DC power from power supply through LRP-104CET’s terminal
block
In the following application topologies, users can find the suitable way to
extend the distance and power on the remote PDs.
2.1 Point to Multi-point
Remote LRP Power through BNC/RJ45 with DC 56V input or Local Power with
External DC input (DC 24V~48V)
