A direct Ethernet connection can carry power and signals between a SMART Controller and a SMART MIC-1 for distances up to 100 meters. To cover longer distances or to minimize electrical interference, you can use an Ethernet signal repeater, powered switch, or Ethernet-to-fiber-optic conversion system.
Ethernet Repeaters, Extenders, and Switches
A device such as an Ethernet signal repeater/extender or a powered Ethernet switch can relay an Ethernet signal along an additional 100-meter span of Ethernet cable. Multiple repeaters, extenders, or switches may be used in series. Such devices may be powered by Power over Ethernet (PoE) or may require dedicated power supplies.
In all cases, ensure that PoE is provided to each SMART MIC-1.
Ethernet-to-Fiber Media Conversion
Commercially available systems can transmit an Ethernet signal between two points using a fiber optic connection, converting it back to a standard RJ45 Ethernet connection on each end. Specifications vary, but these products may allow you to connect a microphone to a SMART Controller over distances up to two kilometers.
Fiber optic lines cannot transmit power. Therefore, you must provide PoE to the SMART MIC-1 on its end of the fiber optic line.
