1. A networking device comprising:
a network communication port receiving a telecommunications signal;
a switch module replicating the telecommunications signal on a plurality of bi-directional communication ports each comprising an output port and a corresponding input port;
a photodetector associated with at least one port of the plurality of bi-directional communication ports to detect a light signal on the input port of the at least one port;
a controller configuring the at least one port of the plurality of bi-directional communication ports as a security enabled port,
the controller receiving a light detection signal from the photodetector and generating, based on the light detection signal, a security alarm for the security enabled port; and
a switch device associated with the at least one of the plurality of bi-directional communication ports and transmitting, to the controller, an insertion signal upon a change of state of the switch device in response to an insertion of a cable into the at least one of the plurality of bi-directional communication ports,
wherein generation of the security alarm is further in response to receiving, at the controller, the insertion signal from the switch device associated with the security enabled port.
