SummAry
Connected to the SecurLAN system, the Optical Cutoff Switch op-
tion enables the system or the operator to take protective action in
the event an intrusion attempt is detected at the physical level of a
network’s infrastructure. unlike older versions of the hardware, the
new Optical Cutoff Switch is not only capable of disrupting the flow of
data through the compromised cable, but certain configurations of the
switch are also capable of re-routing data to a secured cable.

The SecurLAN
®
Optical Cutoff Switch is an option that enables the Secur-
LAN system to take protective action in the event an intrusion attempt is
detected at a protected network data cable (a network configuration known
as a Protected Distribution System or PDS). Depending upon its configu
-
ration, the Optical Cutoff Switch is able to either halt the flow of data or
re-route it to another cable.
