Abstract:
1. A fiber-optic cable attenuator, comprising: an outer casing including an interior region, the outer casing including an entry for receiving a fiber-optic cable into the interior region and an exit positioned in an oppositely disposed location from the entry; a first partition dividing the interior region into a first end chamber and a central chamber, the first end chamber disposed between the first partition and the entry; a second partition positioned in the interior region between the central chamber and the exit, the second partition producing a second end chamber; a first grommet interface positioned relative to the first partition to guide the fiber-optic cable, the first grommet interface for mating with a first grommet and thereby forming an airtight seal with the central chamber; a second grommet interface positioned in the second partition to guide the fiber-optic cable, the second grommet interface for mating with a second grommet and forming an airtight seal with the central chamber; and an exhaust positioned to deposit pressurized air into the central chamber, the pressurized air deflecting the fiber-optic cable, resulting in attenuation of a light signal traveling in the cable.
