3.2.4 Fiber Protection
When an Optical Switch module is installed, its input is connected to the output of the MUX/
DEMUX module, and its two outputs are connected internally to two COM* ports.
The Optical Switch performs APS based on the received optical power level of the incoming
aggregated optical signal. Therefore, the Optical Switch can be used to protect against cable
break, but not against uplink transceiver failure.
The facility protection ensures service continuity in case of a fiber break. The fiber protection
based on the Optical Switch module is supported only for point-to-point topologies.
The following figure shows an Optical Switch Protection application.

When an Optical Switch is installed, the COM1 and COM2* buttons are shown and enabled in
the Web application. In this case, the protection is done on the entire optical signal, which
includes all channels.
The following figure shows the front panel of the MEX6200 as displayed in the Web application.
