In today's high-definition surveillance camera system applications, optical access is the best way to provide the best bandwidth performance in all connections. So many Park monitoring will adopt PON access mode, so how do we choose the right ONU?
ONU is a common optical network unit. Now there are two kinds of ONU devices, one is an ordinary ONU, the other is a ONU with a PoE function, and a different ONU device can be used for different monitoring.
Ordinary ONU is the most commonly used, through optical splitter connected to OLT, providing data, IPTV, voice and other services.
ONU, with the PoE function, came out this year, and also a PoE switch with PON, which combines the two technologies of PON and PoE, which has a great advantage in monitoring the inconvenience of video cameras.
In general, small monitoring or power acquisition can be easy to use ordinary ONU, medium and large monitoring or park monitoring, or want to use PoE power supply monitoring, you can choose the PoE function of the ONU.
