Abstract: An inner sleeve has a main body with an opening therein and a front and back end. The back end has projections or extensions to engage corresponding cavities on another inner sleeve to allow for movement of the inner sleeves relative to a outer portion into which the inner sleeves have been inserted. The outer portion may accommodate any number of inner sleeve pairs.

Abstract: An insert-molded fiber optic transmission component has at least one insert and a main body portion. The main body portion has at least one adjoining surface, a portion of the at least one adjoining surface lying in a first plane. The insert has an engaging face disposed against the outer edge surface and a reference surface adjacent the engaging face, where the reference surface lies in a second plane, and the adjoining surface is adjacent the engaging face of the at least one insert and the first and second planes being parallel to and offset from one another.

Abstract: An interface device includes a body portion having a single-mode waveguide portion including a substantially optically transparent material, a cladding portion defined by channels contacting the waveguide portion, the cladding portion including a substantially optically transparent polymer material, an engagement feature operative to engage a portion of a wafer, and a guide portion operative to engage a portion of an optical fiber ferrule.

Abstract: A two-piece spring push includes a main body portion and a cap. The cap is attached to the main body portion through frictional or interference fits of projections and openings in the two-piece spring push. The two-piece spring push allows for the use of the spring push on larger diameter optical cables as the spring push is assembled on the optical fibers after the optical fibers are terminated in an optical ferrule.

Abstract: A fiber optic connector has a connector outer housing and a connector inner housing. The connector inner housing has a projection to interact with a latch on an adapter into which the connector is inserted. The force required to move the connector outer housing relative to the connector inner housing is less than the force to remove the connector inner housing from the latch. A groove or opening may also be formed in the connector outer housing to effectively shorten the connector outer housing and prevent interaction of the latch with the outer housing, reducing debris.

Abstract: A sleeve has a handle and extensions to engage a fiber optic connector for insertion into and removal from high density adapters. The sleeve may have multiple connectors installed in a single sleeve and it may be removable. The sleeve has first and second extensions to engage the inner and outer housings, respectively, to insert and remove the fiber optic connector from an adapter.

Abstract: A cable holding tool for holding optical fiber ribbons relative one another for preparation has a cable holding portion and an optical fiber holding portion, each having a cover and an opening therein to receive an optical cable and a fiber optic ribbon respectively. The cable holding tool also has at least one channel disposed between the cable holding portion and the optical fiber holding portion to receive and divert at least one optical fiber ribbon from the optical cable disposed in the cable holding portion from the optical fiber holding portion. A spacer is also provided that is movable parallel to the optical fiber groove from a first position to at least one second position to assist in staggering the fiber ribbons.

Abstract: A clip holds a plurality of optical fibers in an array to be inserted into a fiber optic ferrule. The clip has a base member and a lid to hold the optical fibers therebetween. A stacker block assists in making the array by aligning them in a single plane. The optical fibers are then held in alignment for stripping, cleaving and inserting into the fiber optic ferrule.

Abstract: An interface device includes a body portion having a single-mode waveguide portion including a substantially optically transparent material, a cladding portion defined by channels contacting the waveguide portion, the cladding portion including a substantially optically transparent polymer material, an engagement feature operative to engage a portion of a wafer, and a guide portion operative to engage a portion of an optical fiber ferrule.

Abstract: A calibration assembly has a base and mounting elements to mount the base to a laser. The base has a front, middle and rear portions that are used to align the calibration assembly to the laser to cleave optical fibers with the laser. The front portion has a channel to receive the optical fibers, the middle portion has openings to confirm alignment of the laser; and the rear portion has a rear opening used to adjust the pitch and roll of the laser.

Abstract: A multi-fiber ferrule and optical fibers therein make easier contact with other multi-fiber ferrules and connectors with a small fiber tip radius and a modulus of elasticity. A method for qualifying multi-fiber ferrules (and connectors) is also disclosed.

Abstract: A tool-less grouping apparatus has a main body with a top portion and a bottom portion. Dividing members extending between the top and bottom portions make openings for fiber optic connectors. Forward facing surfaces may be on both the top and bottom portions to engage the fiber optic connectors. The portions also have cut-outs that can engage the fiber optic connectors to assist in removing the fiber optic connectors from adapters.

The two-piece spring push allows for the use of the spring push on larger diameter optical cables as the spring push is assembled on the optical fibers after the optical fibers are terminated in an optical ferrule.

Abstract: A unitary multi-fiber ferrule has micro-holes for optical fibers, an optical stop plane for the optical fibers, and a plurality of lenses disposed adjacent the front end, each of the plurality of lenses optically aligned with one of the micro-holes and exposed to air. Multiple rows of optical fibers and lenses may also be used in the unitary multi-fiber ferrule. The unitary multi-fiber ferrule requires less processing and equipment than other current optical ferrules.

Abstract: A field-installable multi-fiber ferrule has two portions and one portion has optical fibers already secured therein. The second portion receives optical fibers to mate with the secured optical fibers. A tool is provided to assist in inserting the optical fibers into the multi-fiber ferrule by aligning and holding the optical fibers while they are secured in the multi-fiber ferrule.
