Abstract: A fence for establishing a secure marine perimeter includes an optic fiber net. The optic fiber net includes an optic fiber wire with an input end and an output end. A light transmitter connects to the input end to introduce an input optic signal into the optic fiber wire. A light receiver connects to the output end to receive an output optic signal from the optic fiber wire. A strength member is incorporated into the optic fiber wire to strengthen the optic fiber net. A processor is connected to the light receiver to generate an output signal based on the output optic signal. The processor compares the output optic signal with the input optic signal and generates an alarm if a difference between the input optic signal and the output optic signal exceeds a predetermined alarm threshold.

Abstract: A fence for establishing a secure marine perimeter includes a floating platform, at least two uprights extending to a predetermined height, at least one anchor, at least one anchor line, an optic fiber net extending from a first predetermined point above the surface of the body of water to a second predetermined point below the surface of the body of water, the optic fiber net including at least one optic fiber with an input end and an output end, a light transmitter connected to the input end introducing an input optic signal into the optic fiber, a light receiver connected to the output end receiving an output optic signal from the optic fiber, and a processor comparing the output optic signal with the input optic signal and generating an alarm if a difference between the input optic signal and the output optic signal exceeds a predetermined alarm threshold.

Abstract: A marine gate includes a gate member submersible in a body of water. At least a first post and a second post support the gate member. The gate member is slidably secured on the first and second posts so that the gate member is movable between first and second locations above and below the waterline. The marine gate includes a winch, a cable extending from the winch to the gate member, and an optic fiber net attached at least to the gate member and extending to the sea floor, thereby establishing an underwater fence. Operation of the winch alters a length of the cable, thereby permitting the gate member to be raised to a closed position and to be lowered to an opened position such that a vessel may pass through the gate when the gate member is in the opened position.

Abstract: A secure fastener for joining fiber optic cables, is presented. The fastener includes a first segment having a first plurality of grooves to accommodate portions of the fiber optic cables, a first plurality of posts, a first plurality of apertures, and a first raised contoured portion and a second segment having a second plurality of grooves to accommodate portions of the fiber optic cables, a second plurality of posts, a second plurality of apertures, and a second raised contoured portion. The first plurality of posts of the first segment cooperates with the second plurality of apertures of the second segment and the second plurality of posts of the second segment cooperates with the first plurality of apertures of the first segment to secure the first and second segments to each other to form the fastener. The first and second raised contoured portions are configured to damage the fiber optic cables if the fastener is tampered with.

Abstract: A security system is described that includes an optical fiber net woven from an optical fiber wire. A light generator introduces an incident light signal into the optical fiber wire. A light receiver receives an exigent light signal from the optical fiber wire. An optical sensor wire is connected to the optical fiber net and is displaced when a force is applied to the optical fiber net. The optical sensor wire receives a patterned incident light signal that is altered upon application of the force applied to the optical fiber net, thereby producing an altered patterned exigent light signal. The light receiver initiates an alarm either (1) if the exigent light signal from the optical fiber wire terminates, or (2) after comparing the exigent patterned light signal with the incident patterned light signal in the optical sensor wire and establishing a deviation, if the deviation exceeds a predetermined threshold.
