  • Patent number: 7566176
    Abstract: A cleaning apparatus (1100) for cleaning an endface (1104) of an optical fiber (1106), wherein a portion of the optical fiber is contained within an interface device (1103) is provided. The cleaning apparatus includes a housing (1114) having an interface portion (1124) adapted to be received by the interface device. The cleaning apparatus further includes a fluid dispensing assembly (1116) at least partially disposed within the housing, wherein at least a portion (1112) of the fluid dispensing assembly engages the endface when the interface portion is received by the interface device. The fluid dispensing assembly is operable to deliver a fluid and a solvent upon the endface when the interface portion of the housing is received by the interface device to aid in the removal of contaminants on the endface. The cleaning apparatus may include a contact cleaning assembly (1304) and/or a microscope (1408).

  • Patent number: 6879439
    Abstract: A microscope (90) having an imaging axis (403) for inspecting an endface (301) of an optical fiber in a fiber-optic connector (201), the fiber-optic connector having multiple fiber-optic endfaces, is provided. The microscope includes a tip (208) capable of interfacing with the connector. The microscope also includes an adjustment assembly (203 and/or 205) attached to the tip, the adjustment assembly adapted to move the imaging axis (210) of the microscope relative to the tip along an axis of motion to selectively align the imaging axis between adjacent endfaces. The microscope further includes a drive assembly (105, 110, 120, 204, and/or 211) interfaced with the adjustment assembly, the drive assembly capable of actuating the adjustment assembly to displace the imaging axis along the axis of motion to selectively align the imaging axis of the microscope between adjacent endfaces. A method of inspecting the connector is also provided.

  • Patent number: 6751017
    Abstract: A microscope for inspecting each optical fiber endface in a multi-fiber connector is disclosed. The microscope includes a tip for interfacing with the multi-fiber connector, a slider assembly connected to the tip, a slider chassis capable of constraining the movement of the slider assembly along an axis of motion, and a cam assembly which forces the slider assembly to move along its constrained axis of motion. The cam assembly is rotated preferably by means of a remotely located adjustment knob. This rotational motion of the cam assembly results in a force against the slider assembly which causes it to move along its constrained axis of motion and, hence, causes the translation of the optical imaging axis of the microscope along the same axis such that each optical fiber endface may be inspected.
