A factory processed and assembled optical fiber arrangement is configured to pass through tight, tortuous spaces when routed to a demarcation point. A connector housing attaches to the optical fiber arrangement at the demarcation point (or after leaving the tight, tortuous spaces) to form a connectorized end of the optical fiber. A fiber tip is protected before leaving the factory until connection is desired.

One or more cables are axially, laterally, and/or rotationally secured to an anchor member. A plug connector can be assembled to or around the anchor member. The anchor member also can be used to handle the cable prior to assembling the plug connector. A connectorization system for assembling plug connectors includes multiple types/sizes of cables; optionally types/sizes of plug bodies; and the anchor member sized and shaped to connect a selected one of any of the cables with any of the plug bodies of the connectorization system.

A ferrule mold having a reverse-image of a through-hole array for optical fibers is formed. A non-polymeric ferrule material is deposited in the reverse-image mold, followed by removing the mold to create a multi-fiber connector ferrule having at least two fiber through-holes. An optical fiber is inserted in each through-hole until each fiber endface is positioned approximately even with a connection surface of the ferrule. A fiber recess for each of the optical fibers is formed such that each fiber is recessed from the multi-fiber ferrule connection surface by a distance of at least 0.1 micron. The recess may be formed by differential polishing of the non-polymeric ferrule and endfaces of the optical fibers. Alternatively, a layer of spacer material may be deposited over the multi-fiber ferrule connection surface. An antireflection coating is deposited over the ferrule connection surface and ends of the recessed fibers.

Provided is an optical module assembly including: an optical module body in which an optical transceiver is built; a first connector coupled to one side of the optical module body to be connected to an optical transceiver in the optical module body; a second connector, in which an insertion hole for inserting an optical cable is formed and the optical cable is inserted into the insertion hole, connected to the first connector to connect the optical cable to the optical transceiver connected to the first connector; and a disconnection unit installed on the first connector and the second connector to release the connection between the first connector and the second connector by rotation.

The present invention provides a dust-proof adapter comprising an adapter body, a flexible element, and a cap, wherein the adapter body has an opening at a coupling side and a ring-shaped surface surrounding the first opening, the flexible element is arranged onto the ring-shaped surface, and the cap detachably covers the adapter body for protecting the first opening. When the cap is covered on the first opening, the cap applies an action force along an axial direction of the adapter body on the flexible element thereby achieving air-tight and dust-proof effect.

A sealing enclosure is configured to connect to a mating enclosure. The sealing enclosure loosely receives a connector within a connector volume so that the connector, which may be of a standard type used in electronic or optic data transmission, may be displaced within a plug face at the forward end of the connector volume. The connector may compensate variations in the position of a mating connector with respect to the mating enclosure. The sealing enclosure allows to seal off the connector volume and engage the sealing enclosure with a mating enclosure in a single motion. This is affected by having a cable seal interposed between an inner body and an outer body. If the outer body is moved forward to engage the mating connector, the cable seal is squeezed between the cable and the inner body sealing off the connector volume at the rearward end of the inner body.

An optical module includes a substrate in which a through hole or a recess is formed; a first component that is arranged in the through hole or the recess of the substrate, and is bonded to an inner wall surface of the through hole or the recess by a thermosetting adhesive in a portion of a gap between the first component and the inner wall surface of the through hole or the recess; and a second component that is connected to an electrode on one surface of the first component and an electrode on one surface of the substrate, across the gap between the first component and the inner wall surface of the through hole or the recess.

The present invention relates to a fibre optic fusion splicing technique, in particular to a fibre optic fusion splicer for reliable and stable fibre optic fusion splicing, that is characterized by comprising: an alignment part for fixing and aligning first and second optical fibres that are to be fusion spliced; a fusion splicing module having an electrode bar for fusion splicing the first and second optical fibres that are fixed to and aligned in the alignment module; an optical module for photographing the aligned state of the first and second optical fibres aligned by the alignment module, and the fusion-spliced state of the first and second optical fibres fusion-spliced by the fusion splicing module; a support part in which the fusion splicing module and the optical module are mounted; and a lift module for moving the support part up and down.

A driving force generating unit 27 that generates a driving force; a movable portion 29 that is movable in a crossing direction crossing an axial direction of the ferrule by the driving force of the driving force generating unit; a friction contact portion 31 that is provided on the movable portion to be in contact with an outer periphery of the ferrule, the friction contact portion being configured to rotate the ferrule by a frictional force when the movable portion is moved; and a controller that controls the driving force generating unit are provided, and the controller controls the driving force generating unit to move the movable portion in one direction of the crossing direction for rotating the ferrule by the friction contact portion for measuring the eccentricity, and further move the movable portion to the one direction of the crossing direction for rotating the ferrule by the friction contact portion for adjusting the eccentric direction to the predetermined direction.

A fiber optic connector having a set of opposing pins set in a recess configured to accept a corresponding spring therein. The springs are placed on either side of the fiber optic cable bundle and secured within a pinkeep. The dual or outer springs help prevent rotation of the ferrule assembly during use.
