摘要： An optical switch for switching the light output of one optical fiber into another optical fiber is disclosed. The optical switch includes an imaging system having a symmetry such as a spherical reflector. The switch also includes a group of optical fiber end faces including a first optical fiber end face via which light is transmitted to the imaging system and second and third fiber end faces. A translation mechanism is provided for linearly translating the group of fiber end faces and imaging system relative to one another between a first position in which the light from the first fiber end face is imaged by the imaging system into the second fiber end face and a second position in which light from the first fiber end face is imaged by the imaging system into the third fiber end face. The switch may be used to selectively remove a node from a fiber optic network having a ring like configuration.

摘要： In accordance with the present invention, a wavelength selective passive filter is sealed onto the end of a ferrule to form a connector which may be used to increase the wavelength sensitivity of fiber optic components. In particular, such connectors may be used to increase the wavelength isolation of WDM devices.

摘要： A method and apparatus for characterizing light emitting diodes (10) and PIN diodes (100) for coupled power degradation with varying offset is disclosed. An optical-electronic device such as a light emitting diode (10) or PIN diode (100) is scanned by an optical fiber (20) to obtain the output intensity of the LED (10) or the detection sensitivity of the PIN diode (100) as a function of position.
