Patent number: 6765658Abstract: A cassette for preparing an end face of an optical fiber includes a housing that defines a window, and a supply reel and a take up reel disposed within the housing. The cassette also has a preparatory tape, advancing between the supply reel and the take us reel, for preparing the end face of the optical fiber. In addition, the cassette includes means for directing the tape by the window defined by the housing such that the tape contacts and prepares the end face of the optical fiber.Type: GrantFiled: August 16, 2002Date of Patent: July 20, 2004Assignee: McDonnell Douglas CorporationInventors: Sang Van Nguyen, Foad Towfiq, John Andrew White

Patent number: 6733184Abstract: A method and apparatus is provided for mounting any one of a plurality of types of connectors upon the end portion of a fiber optic cable. The automated fiber optic connectorization apparatus includes a memory device for storing data relating to a plurality of types of connectors. The automated fiber optic connectorization apparatus also includes a controller for receiving input from a system operator or other source that specifies the type of connector to be mounted upon the specified fiber optic cable, the polishing geometry, and the optical performance specifications. Based upon this input, the controller determines the components required to mount the specified type of connector upon the end portion of the fiber optic cable based upon the data stored by the memory device. The automated fiber optic connectorization apparatus also includes means for obtaining the necessary components and means for assembling these components upon the end portion of the fiber optic cable.Type: GrantFiled: August 16, 2002Date of Patent: May 11, 2004Assignee: McDonnell Douglas CorporationInventors: Sang Van Nguyen, Foad Towfiq, John Andrew White
