Optical sensor modules and methods of fabrication are described. In an embodiment, an optical component is mounted on a module substrate. In an embodiment, a pillar of stacked wireballs adjacent the optical component is used for vertical connection between the module substrate and a top electrode pad of the optical component.

A fiber optic cable assembly includes a fiber optic cable and a fiber optic connector. The cable includes a jacket having an elongated transverse cross-sectional profile that defines a major axis and a minor axis. Strength components of the cable are anchored to the connector. The fiber optic connector includes a multi-fiber ferrule defining a major axis that is generally perpendicular to the major axis of the jacket and a minor axis that is generally perpendicular to the minor axis of the jacket. Certain types of connectors include a connector body defining a side opening that extends along a length of the connector body; a multi-fiber ferrule configured for lateral insertion into the connector body through the side opening; and a cover that mounts over the side opening after the multi-fiber ferrule has been inserted into the connector body through the side opening.

An optical connector includes: optical fibers including bare portions and covering portions covering the bare portions; a ferrule that accommodates parts of the optical fibers where the bare portions are exposed; a stress relaxation portion that accommodates parts of the optical fibers where the covering portions are formed and relieves a stress acting on the optical fibers; and a boot that has an insertion hole through which the optical fibers are inserted and that connects the ferrule and the stress relaxation portion. The ferrule, the boot, and the stress relaxation portion are separately formed and fixed to each other. The stress relaxation portion includes a constricted portion therein.

A paired simplex fiber optic connector assembly comprises a clip that holds two simplex LC connectors together to yield a duplex connector that can be plugged into a duplex adapter. In some embodiments, the two simplex connectors are held in place by rails formed on both sides of the clip. In other embodiments, a side arm is formed on each side of the clip, the side arm comprising a hub that extends from the clip and a non-circular flange formed on the end of the hub. The flange is configured to engage with channels formed on the sides of the simplex connectors, thereby holding the simplex connectors in place. The simplex connectors are attached to the clip by rotating the connectors about the flange, thereby engaging the channels with the flanges.

Reversible optical connectors, and associated devices and methods are provided. In one embodiment, a connector for a communication cable includes a housing comprising a cavity, and a first plug and a second plug coupled to a distal portion of the housing. The first and second plugs are connected to the housing such that the first and second plugs are independently rotatable with respect to the housing. The connector further includes a latch actuator coupled to the housing and configured to disengage one or more latches from an outlet. By rotating the plugs 180 degrees and turning the connector over, the relative arrangement or position of the two plugs can be switched or reversed. The plugs can be rotated or reversed without completely disassembling the connector, in some embodiments. Accordingly, embodiments of the present disclosure can improve workflows for a user or operator that in a high-density networking setting.

Embodiments of the disclosure relate to an optical fiber cable having at least one optical fiber, a cable jacket and a foam layer. The cable jacket includes an inner surface and an outer surface in which the outer surface is an outermost surface of the optical fiber cable. The inner surface is disposed around the at least one optical fiber. The foam layer is disposed between the at least one optical fiber and the cable jacket. The foam layer is made of an extruded product of at least one thermoplastic elastomer (TPE), a chemical foaming agent, and a crosslinking agent. The foam layer has a closed-cell morphology having pores with an average effective circle diameter of less than 100 .Math.m. Further, the foam layer has a compression modulus of less than 1 MPa when measured at 50% strain.

A small form factor optical connector holding two or more LC-type optical ferrules is provided. The optical connector includes an outer body, an inner front body accommodating the two or more LC-type optical ferrules, a pair a resilient latches and corresponding recess for the resilient latch, ferrule springs for urging the optical ferrules towards a mating receptacle, and a back body for supporting the ferrule springs. The outer body and the inner front body are configured such that four LC-type optical ferrules are accommodated in a small form-factor pluggable (SFP) transceiver footprint or eight LC-type optical ferrules are accommodated in a quad small form-factor pluggable (QSFP) transceiver footprint. A mating receptacle (transceiver or adapter) includes a receptacle hook and a housing with an opening that accommodates the receptacle hook in a flexed position as the optical connector makes connection with the mating receptacle by introducing the receptacle hook into an optical receptacle hook recess.

Devices such as multiports comprising connection ports with associated securing features and methods for making the same are disclosed. In one embodiment, the device comprises a shell, at least one connection port, at least one securing feature passageway, and at least one securing feature. The at least one connection port is disposed on the multiport with the at least one connection port comprising an optical connector opening extending from an outer surface of the multiport to a cavity of the multiport and defining a connection port passageway. The at least one securing feature is associated with the connection port passageway, and the at least one securing feature is disposed within a portion of the at least one securing feature passageway.

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.

An optical fiber connector, comprising a main shaft, a connecting piece, and a lock cap. The main shaft comprises a head end and a tail end that is away from the head end. A through hole extending from the head end to the tail end is disposed in the main shaft. The connecting piece is fixedly connected to the head end and partially accommodated in the through hole. The lock cap includes a sealing portion and a connection portion that is connected to a side of the sealing portion. The sealing portion is rotationally connected to an outer side of the head end. The connection portion is located on a side that is of the head end and that is away from the tail end.
