Active Optical Network

AON and PON in comparison

Active Optical Networks ( AON ) are fiber optic networks which - in contrast to Passive Optical Networks (PON) - also contain “active” components such as switches , routers or multiplexers . As a result, they can bridge longer distances and transmit greater bandwidths than PON, but they also require higher installation and operating costs.

An application of AON that was widespread in the 1990s and 2000s is the HYTAS from Deutsche Telekom. Since around 2010, Ethernet in the variants 1000BASE-BX10 and 100BASE-BX10 has been used almost exclusively .
