Abstract: An optical cable signaling system includes an optical cable and an endpoint device that is connected to the optical cable. An optical cable signaling device is provided in the optical cable signaling system for signaling using the optical cable, and includes a first optical cable manipulation subsystem and a second optical cable manipulation subsystem. An optical cable signaling actuator on the optical cable signaling device is configured to move the first optical cable manipulation subsystem relative to the second optical cable manipulation subsystem to physically manipulate the optical cable such that a parameter of an optical signal transmitted through the optical cable changes. An optical cable signaling engine in the optical cable signaling device is configured to actuate the optical cable signaling actuator to communicate information to the endpoint device via changes in the parameter of the optical signal transmitted through the optical cable.

Abstract: A method includes monitoring a parameter of an optical signal transmitted between two endpoints via an optical fiber. The optical fiber may be manipulated to modulate the parameter without disconnecting either endpoint of the optical fiber. Data in accordance with the modulation of the monitored parameter may be identified. A portion of the optical fiber may be wrapped around a high order mode filter (HOMF) that includes a grooved cylinder or mandrel suitable for wrapping the optical fiber. The monitored parameter may include a received power parameter. The HOMF may be a variable diameter HOMF that can be transitioned between a wrapped or attenuating diameter and an unwrapped or non-attenuating diameter in accordance with a data pattern. The wrapped and unwrapped diameters may be defined relative to a threshold diameter, above which the monitored parameter may be independent of the diameter.
