Downlink Fiber Connections
Fiber optic technology allows for longer cabling than any other media type. A
100BASE-FX single-mode fiber link from the chassis can connect to a subscriber up
to 15 km away. The Media Converter Customer Premises Equipment (CPE) is
installed inside a subscriber’s premises, so there are no active outside components
between the CO and the end user.
The figure below illustrates a basic switch to CPE connection.
