Abstract:
1. A fiber-optic cable attenuator, comprising: a casing including an entry point and an exit point, the casing including an interior chamber; a cover for covering the casing; first and second split grommets; a first grommet interface positioned at an entry point of the casing, the first grommet interface for housing the first split grommet and positioning a fiber-optic cable at the entry point of the casing, the first grommet interface in combination with the fiber-optic cable and the cover beginning an airtight seal of the interior chamber; a second grommet interface positioned at an exit point of the interior chamber for housing the second split grommet, the exit point positioned in an oppositely disposed location of the interior chamber from the entry point and positioning the fiber-optic cable at the exit point, the second grommet interface in combination with the cover and the fiber-optic cable completing the airtight seal of the interior chamber; and at least one indenter movable through the casing and capable of deflecting the fiber-optic cable in the interior chamber, resulting in deflection of the cable causing attenuation of a light signal traveling in the cable; wherein the indenter is a canister of pressurized air.
