PoE media converters have the same functionality as PoE injectors, but they also provide conversion from fiber to copper cabling. PoE media converters are power sourcing equipment (PSE) that provide distance extension over fiber optic cabling to PoE powered devices (PDs), like VoIP phones, wireless access points, and security cameras.
PoE media converters are used when a network device is far away from PoE powered devices (PDs). PoE media converters are used to overcome the distance limitation of copper cables, like other fiber optics media converters, but with the functionality of power sourcing equipment (PSE).
In this application, the PoE media converter is deployed between a network switch, such as a PoE switch or an Ethernet switch with a fiber uplink port, and the powered device (PD), such as a security camera or wireless access point.
The third-party switch on the left side of the application can be a fiber switch that distributes multiple fiber links to remote locations or a copper switch with RJ-45 ports.
Suppose the third-party switch is a network switch with a fiber uplink port. The application would only need one PoE media converter to be installed far from a fiber switch and within a maximum distance of 100 meters from the PoE powered device (PD).
Suppose the third-party switch is a network switch with RJ-45 ports. The application would need two media converters. The media converter would be used to convert the copper cabling from the switch to fiber optic cabling. A PoE media converter would convert the fiber to copper functions as PoE power sourcing equipment (PSE) injects PoE power (DC power) over the RJ-45 port to the UTP cable.
In both scenarios, the PoE media converter is installed up to 100 meters away from the PoE powered device (PD) and connects to the PoE powered device over a UTP cable to supply power and data. The maximum distance that the fiber links can extend is 140 kilometers, but the range entirely depends on the fiber type, data rate, and optical power of the equipment. The PoE media converter auto-negotiates with the PD and will supply only the amount of power that is being requested by the PD. Here are the different levels of power that a PoE media converter will supply:

All media converters are installed in a network to eliminate the distance limitation of Ethernet cables, and to preserve investments in your existing infrastructure. The main difference between a media converter and a PoE media converter is that the PoE media converter has the functionality of power sourcing equipment (PSE). The PoE media converter not only sends data but also sends power simultaneously to PoE powered devices (PDs) over Ethernet cables.
Both commercial and industrial PoE media converters perform the same function; commercial media converters operate in temperature-controlled environments from 0° to 50°C (32° to 122°F), while industrial media converters operate at extreme temperatures, ranging from -40 ° to 75°C (-40° to 167°F).
Industrial PoE media converters can operate from -40º to 75ºC and -40º to 85ºC. They are deployed in harsh and extreme environments, such as factory and building automation, transportation, utility, government agencies, etc. Industrial PoE media converters have specialized components that are made to withstand extreme temperatures.
Commercial PoE media converters operate between 0° to 50ºC. They are used in indoor and controlled-temperature environments, such as schools, universities, office campuses, and airports.
PoE media converters are classified as power sourcing equipment (PSE); they provide power to powered devices (PDs) using standard UTP cables that carry the Ethernet data. PoE media converters can come with various fiber connector types, and support Ethernet speeds from 10mbps to 10gbps. Omnitron Systems is a privately held company headquartered in Irvine, California, and all products are manufactured in the United States. We provide a lifetime warranty on all managed and unmanaged media converters and PoE media converters.
