Fiber optic connectors comprising multiple footprints along with cable assemblies and methods for making the same are disclosed. In one embodiment, the optical connector comprises a housing and a ferrule. The housing comprises a longitudinal passageway between a rear end and a front end. The fiber optic connector may be converted from a first footprint to a second footprint by a conversion housing that fits about a portion of the housing. The optical connectors disclosed may be tunable for improving optical performance and may also include a spring for biasing the ferrule to a forward position as desired.

Devices having at least one connector port associated with a rotating securing features are disclosed. A device for making optical connections comprising a shell, at least one connection port, and at least one rotating securing feature is disclosed. In one embodiment, the at least one connection port is disposed on a device with at the least one connection port comprising an optical connector opening extending from an outer surface of the device into a cavity of the device and defining a connection port passageway. The at least one rotating securing feature is associated with the connection port passageway, and the at least one rotating securing feature is secured to the device along a rotational axis that is not aligned with a longitudinal axis of the at least one connection port.

An optical fiber connector according to the present disclosure includes an inner housing, a first outer housing and a second outer housing. The inner housing has a first wall, a second wall, a third wall and a fourth wall, wherein the first wall faces the third wall and connects with the second and fourth walls. The first outer housing is positioned to surround the inner housing. The second outer housing is positioned to surround the inner housing and engage the first outer housing. A key arm extends from the second outer housing and is configured to position on the first wall or the third wall of the inner housing. When the inner housing is inserted into an optical fiber adapter, the key arm is inserted into the key recess of the optical fiber adapter.

A connector comprises an upper surface finger-resting portion that extends in the longitudinal axial direction on the outer periphery of the gripping portion, and on which the first finger is placed, a lower surface finger-resting portion on which the second finger or the third finger is rested when the connector is gripped by placing the first finger on the upper surface finger-resting portion, and a guide protrusion portion that is arranged on the same straight line as the upper surface finger-resting portion in the longitudinal axial direction and determines the position to be inserted, in which the connector is directly fitted into the receiving-side connector by directing the finger tip of the first finger that is placed on the upper surface finger-resting portion to the guide groove of the receiving-side connector and inserting the connector.

An adapter block assembly includes at least one adapter block; a circuit board; a first contact set; and a second contact set. The contact sets are disposed at apertures defined in the adapter block and rotated 180° from each other. Each adapter block includes first and second latching arrangements that retain separately manufactured alignment arrangements against movement along the passages. The first latching arrangements include latching arms disposed at the apertures. The second latching arms include ramps and stops disposed opposite the apertures. Optical connectors suitable for plugging into the adapter block include an outer housing having an area of increased thickness of hold a storage device and an inner housing with a channel to accommodate the area of increased thickness of the outer housing.

In a mateable pair of MPO connectors, a first connector has a first key structure and a second key structure, each of which is moveable between a first position and a second position thereof. When the first key structure is in the first position, the second key structure is in the second position and vice versa. The second connector similarly has a first key structure and a second key structure, each moveable between a first position and a second position thereof, and when the first key structure is in the first position, the second key structure is in the second position and vice versa. A polarity of at least one of the first connector and the second connector is reversible without disassembly thereof.

An optical fiber alignment mechanism (100) operates to align optical fibers (102). The mechanism can include a key element (120, 130) arranged on the cladding (112) of an optical fiber (102). The key element (120, 130) can engage with a corresponding element of another optical fiber (102) to align the cores (108) of the mating optical fibers. The key element (120) of an optical fiber (102) can also be inserted into a corresponding keyway (226) of a fiber alignment hole (222) of a ferrule (200) such that the optical fiber (102) is oriented properly within the ferrule (200).

A fiber optic connector assembly incorporates features that improve structural rigidity and the integrity of transmitted signals. These features also facilitate a technique for reversing polarity of the connector assembly with little or no risk of twisting the optical fibers and without requiring the housing assembly to be disassembled. The connector is marked or embossed with transmit and receive connector labels that facilitate visual identification of the polarity of the connector. One side of the duplex connector can be marked with “A” and “B” labels corresponding to the receive and transmit connectors, respectively. The opposite side of the duplex connector can be marked with two “A” labels corresponding to the receive and transmit connectors, respectively. Thus, a user can readily identify whether the connector is configured for “A-B” polarity or “A-A” polarity.

An optical adaptor for mounting to a receptacle to optically couple connectorized optical cables comprises a coupling element to provide a passageway for inserting a respective ferrule of a first and a second optical connector terminating a first and a second optical cable. The optical adaptor further comprises a mounting element to mount the first optical connector to the receptacle, the mounting element being configured to be insertable in the receptacle, and a fixing element to fix the mounting element to the receptacle. The mounting element is formed as a hollow body to receive the coupling element and configured to fix the coupling element to the receptacle.

A connector part of a connector unit having a connecting structure and a guiding assembly, wherein the connecting structure is moveable between at least two positions at least one of the at least two positions being a connection position and wherein the guiding assembly determines a movement of the connecting structure in the connection position. The guiding assembly has a first keyway, at least a second keyway and at least one key being engaged in the first keyway and the at least second keyway to bring the connecting structure in the connection position due to a movement of the key in the first keyway and the at least second keyway.
