A plug connector is attachable with an optical fiber cable and is connectable with a receptacle connector. The receptacle connector comprises a receptacle shell. The plug connector comprises a front holder, a cable holding portion, a rear holder and a coupling member. The front holder is made of metal. The front holder is mated with the receptacle shell when the plug connector is connected with the receptacle connector. The cable holding portion is made of metal. The cable holding portion is configured to hold the optical fiber cable. The rear holder guards the cable holding portion. The rear holder comprises, at least in part, a thermal insulating portion made of non-metal material. The coupling member couples the front holder and the rear holder with each other. Each of the coupling member and the front holder is in contact with the rear holder only on the thermal insulating portion.

A feedthrough (10) for an element (100) is described, comprising: a body (500), a cap assembly, comprising a cap (200) and optionally a follower (300), and a sealant (400), having respective passageways therethrough, defining an axis A, for receiving the element (100) therethrough; wherein the body (500) is couplable to a wall W of a hermetically-sealed vessel V having an aperture A for the element (100) therethrough and wherein the passageway of the body (500) is adapted to retain, at least in part, the sealant 400 and optionally the follower (300) therein; wherein the cap (200) is releasably couplable to the body (500); wherein the feedthrough (10) is configurable in: a first configuration, wherein the cap (200) is coupled to the body (500), wherein matching faces of the cap assembly and the body (500) are mutually spaced apart by a gap and wherein the element (100) extends through the respective passageways; and a second configuration, wherein the cap (200) is coupled to the body (500), wherein the matching faces (230, 520) of the cap assembly and the body (500) abut and wherein the element (100) extends through the respective passageways; wherein the cap assembly is adapted to axially compress the sealant (400) against the body (500), thereby causing the sealant (400) to radially compress against the element (100) and to form a hermetic seal between the body (500) and the element (100), in the second configuration.

An optical circuit is provided in which electric circuit parts and optical circuit parts are integrated in a stack on a printed substrate. The optical circuit is provided with a lid having a temperature regulation function that uses a temperature control element and an optical fiber block capable of optical input and output. Temperature control of optical circuit elements can be efficiently performed by mounting electric circuit parts and optical circuit parts on a printed substrate in advance by a reflow step using OBO technology and subsequently attaching a lid that includes a temperature control element.

Pairs of windows are cut into a distribution cable at various points along the length to couple some of the optical fibers of the distribution cable to drop cables. A wrap-type sealing arrangement can seal a first window of each pair. An enclosure-type sealing arrangement can seal a second window of each pair. The enclosure includes a splice tray and cable storage. Optical adapters and/or a passive splitter also may be disposed within the enclosure.

The present disclosure relates to semiconductor structures and, more particularly, to a moisture seal for photonic devices and methods of manufacture. The structure includes: a first trench in at least one substrate material; a guard ring structure with an opening and which at least partially surrounds the first trench; and a second trench at a dicing edge of the substrate, the second trench being lined on sidewalls with barrier material and spacer material over the barrier material.

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 integrated circuit (IC) structure includes: a substrate including a fiber slot formed in an upper surface of the substrate and extending from an edge of the substrate, and an undercut formed in the upper surface and extending from the fiber slot; a semiconductor layer disposed on the substrate; a dielectric structure disposed on the semiconductor layer; an interconnect structure disposed in the dielectric structure; a plurality of vents that extend through a coupling region of the dielectric structure and expose the undercut; a fiber cavity that extends through the coupling region of dielectric structure and exposes the fiber slot; and a barrier ring disposed in the dielectric structure, the barrier ring surrounding the interconnect structure and routed around the perimeter of the coupling region.

An airtight device includes a tank, a sink and a feedthrough module. The sink is disposed inside the tank, and an opening is formed on the sink. The feedthrough module is disposed on the opening. The feedthrough module includes a base, a sealing component, a covering component, a transmission component and a plurality of fixing components. A groove is formed on the base. A part of the sealing component is disposed inside the groove. The covering component is assembled with the base and adapted to press the sealing component. A plurality of fixing holes is formed on the covering component. The transmission component is assembled with the covering component. The plurality of fixing components is adapted to insert into the plurality of fixing holes and engage with the base for pressing the sealing component by shortening a distance between the base and the covering component.

A crimp comprises a hollow crimp body that is open at each end and includes, a first end, a first crushable crimp tube for crimping onto a connector; and at a second end a second crushable crimp tube for crimping onto a cable, the portion of the crimp between the said ends including a recess for engagement by a closure housing.
