Abstract: A multi-fiber ferrule has lenses that have different prescriptions to disperse the light emitted from the multi-fiber ferrule. Alternatively, the lens for each individual optical fiber can be moved relative to the optical fiber or the optical fiber opening in the multi-fiber ferrule to cause the laser beam exiting the multi-fiber ferrule to be redirected into a structure that absorbs or blocks the laser.

Abstract: An fiber-optic connector assembly includes a fiber optic ferrule and a connector, which engage an optical transceiver component. The fiber optic ferrule engages a mating plane of a lens array in the optical transceiver component and floats within the connector. The engagement of the assembly and the optical transceiver component may be removable rather than fixed. The fiber optic ferrule also engages a mechanical interface to account for three degrees of freedom, while the engagement of the mating surfaces account for another three degrees of freedom.

Abstract: A fiber optic connector along with a tool allows for the changing of the polarity of the fiber optic connector. Keys may be installed in both the top and the bottom of the fiber optic connector, one in a first position and the other in a second position. Using the tool in one back-and-forth motion, the polarity of the fiber optic connector can be changed. The keys have a configuration that resist an incorrect insertion and provide better retention of the keys in the correct configuration due to a better retention force.

Abstract: An interconnect system is provided that involves pre-installing a connector housing an optical connector in an adapter and a ferrule of the same optical connector on a cable. The ferrule terminates one or more groups of optical fibers, and a ferrule push component is also pre-installed on the same group(s) of optical fibers. The connector housing is configured to receive and retain the ferrule and ferrule push component without being removed from the adapter to simultaneously form the optical connector and install the optical connector in the adapter. Embodiments such an interconnect system involving high fiber-count cables and related installation methods involving many optical connections are disclosed.

Abstract: An assembly of two fiber optic ferrules allows for the mating of a CWDM fiber optic ferrule with a non-CWDM fiber optic ferrule. The CWDM fiber optic ferrule has optical fibers that carry optical beams with at least two different wavelengths, which the non-CWDM ferrule has optical fibers that carry only one wavelength. The CWDM fiber optic ferrule and the non-CWDM fiber optic ferrule have optical fibers that are inserted along parallel axes. The non-CWDM fiber optic ferrule has a lens pitch that matches the CWDM ferrule.

Abstract: A fiber optic connector assembly is mated with a bracket on a printed circuit board at one end and inserted into a backplane adapter that is adjacent a backplane. In particular a spring push in slidingly attached to the bracket and also to the housing of the fiber optic connector assembly. The housing of the fiber optic connector assembly insertable into the backplane adapter using passive alignment features. A fiber optic ferrule in the fiber optic connector assembly is biased in a forward direction by a spring in the spring push. At the same time the spring allows for movement of the spring push within the housing to allow for movement of the printed circuit board relative to the backplane adapter.
