A POE ONU is a type of Optical Network Unit that supports Power over Ethernet (POE). What is POE ONU? What are the differences between POE ONU and ONU? After reading the article, you can understand what the POE ONU is and why we need to use it.
What is ONU?
In telecommunications, an Optical Network Unit (ONU) is a device used in fiber optic communication, particularly in Passive Optical Networks (PON). It converts optical signals to electrical signals in fiber network.
What is POE?
POE (Power over Ethernet) is a technology that transmit data signals and power over Ethernet cables to POE-enabled devices, such as monitors, VoIP phones and wireless access points. One of the major benefits of POE is that it eliminates the need for additional power since the interface typically uses a standard Ethernet connection and power supply can be provided through this interface. POE technology simplifies the cabling process by transmitting data and power over a single cable, reducing the need for additional power cables.
What is POE ONU?
A POE ONU is a type of Optical Network Unit that supports POE. It can deliver power over Ethernet to devices like VoIP phones, and cameras, eliminating the need for separate power adapters.
The ability to transmit both power and data through a single Ethernet cable simplifies the installation process. By using POE, you can reduce the power outlets and adapters needed for connected devices.
Why we need to use POE ONU?
Power supply: A network surveillance can be considered as a system, there are at least dozens of surveillance cameras. In order to conveniently, flexibly and quickly supply power to the cameras, POE ONU power supply is an ideal choice.
Cost-efficient: A network cable transmit data and power supply at the same time. It can not only simplify the wiring, but also be very flexible to save the labour and time cost. At the same time, it can also solve the problem of long-distance transmission.
Long distance connection: ONU is a part of PON network. PON technology has the advantages of long transmission distance, large bandwidth, and simple expansion, etc. Even if the points of devices are scattered, such as some cameras and control centre are far away, it can achieve easy transmission.
What is the difference between ONU and POE ONU ?
Power supply: The one with POE has multiple POE power supply ports, which is not available in common ONU devices. Common ONU is usually with PON ports, but the one with POE has both PON and POE ports, which not only makes the connection flexible, but also saves another power supply for cameras.
The big difference them is that the former can only be used as a kind of optical network unit to provide data transmission. The latter can not only transmit data, but also connect the camera through its POE port to power it. It has a great advantage in some special environments, such as harsh environments and inconvenient power supply.
Our Baudcom GPON ONU supports to work with IP camera, IP phone, wireless AP and other network devices, and supply power to these devices. It works with central device OLT to implement integrated management, long-distance fault location and decrease maintenance workload. It is metal casing design and suitable for FTTB/FTTH.
