The unit is also plugged into an AC or DC power source so that it can inject Power-over-Ethernet (PoE) into the ODU. One power injector is required at each end of a link. You have the following two options:
- AC Power Injector: This power injector accepts AC input only and is a lower-cost unit that supports 32° to 104° F (0° to 40° C) temperature ranges.
- AC+DC Power Injector: This is an enhanced power injector that accepts either 100-240VAC or 48VDC input. It also tolerates a greater temperature range (-40° to 140° F or -40° to 60° C) and can power a device such as a video camera or wireless access point on the Auxiliary port of the ODU. The AC+DC injector can also be configured in redundant configurations for high availability requirements.
