Downlink Fiber Connections
Fiber optic technology allows for longer cabling than any other media type.
A 100BASE-BX single-mode fiber link from the switch can connect to a
subscriber up to 10 km away. A 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.
