Patent number: 7359584Abstract: The present invention relates to a device for use in a fiber optic system that may be a communication system, a sensing system or other system using guided-wave optical components. Reducing the number of lenses required to couple the waveguides and the free-space paths in the device offers the dual advantages of a reduced component count and simplified alignment. In an exemplary device having a first and second waveguides, a birefringent optical system defines bi-directional, polarization-dependent free-space paths. One of the bidirectional, polarization-dependent, free-space paths couples at least the first waveguide to the second waveguide. The birefringent optical system includes at least one prism for bending one of the polarization-dependent paths in a clockwise direction and one of the polarization-dependent paths in a counterclockwise direction.Type: GrantFiled: December 22, 2006Date of Patent: April 15, 2008Assignee: ADC Telecommunications, Inc.Inventors: Pingfan P.

Patent number: RE40622Abstract: A fiber optic connector has two ferrules contained within a single connector housing with the ferrules positioned in parallel, spaced-apart alignment. The connector includes a first mating fastener exposed on exterior sides of the connector housing. A fiber optic adapter has an open end to slidably receive the connector housing. The adapter includes two parallel sleeves contained within the adapter housing and aligned with the ferrules of the connector. The adapter includes a second mating fastener exposed to an interior of the adapter housing to releasably mate with the first mating fastener when the connector housing is in the full insert position.Type: GrantFiled: October 26, 2001Date of Patent: January 13, 2009Assignee: ADC Telecommunications, Inc.Inventor: Liang-Ju Lu
