Application diagram
The POC extender 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 POC extender supports two ways for a power source to inject 802.3af/at PoE to
remote standard PDs.
Remote POC power from the POC injector/switch over coaxial cable.
Local DC power from the power supply through the POC extender terminal block.
In the following application topologies, users can find the suitable way to extend the
distance and power on the remote PDs.
Point to multi-point
Remote POC power through BNC/RJ45 with DC 56 V input or local power with an
external DC input (DC 24~48 V).
