The photonic device may be actively or passively aligned with the optical bench. After achieving optical alignment, the submount of the photonic device is fixedly attached to the base of the optical bench. The optical bench subassembly may be structured to be hermetically sealed as a hermetic feedthrough, to be hermetically attached to a hermetic optoelectronic package.

An optical fiber connector sub-assembly optical fiber connector sub-assembly for an optical fiber connector includes a ferrule holder carrier portion and a sleeve portion disposed rearward of the ferrule holder carrier portion along an axis of the connector. The sleeve portion is configured to be connected to the ferrule holder portion to permit relative articulating movement between the sleeve portion and the ferrule holder carrier portion, and the sleeve portion and the ferrule holder carrier portion are configured to be rotatingly fixed to one another.

A connector device includes a first connector part and a second connector part. The first connector part has a first outer housing and a first sub-assembly accommodated in the first outer housing. The first sub-assembly has a first ferrule and a first latch member fastening the first sub-assembly to the first outer housing. The second connector part has a second outer housing and a second sub-assembly accommodated in the second outer housing. The second sub-assembly having a second ferrule and a second latch member fastening the second sub-assembly to the second outer housing. The second outer housing mating with the first outer housing in a state of coupling the first connector part to the second connector part.

Methods of reshaping ferrules used in optical fiber cables assemblies are disclosed. The reshaping methods reduce a core-to-ferrule concentricity error (E), which improves coupling efficiency and optical transmission. The methods include measuring a true center of the ferrule, wherein the true center is based on an outer surface of the ferrule; and reshaping at least a portion of the ferrule to change the true center of the ferrule, wherein the reshaping includes enlarging a portion of the ferrule. A variety of reshaping techniques are also disclosed.

The present disclosure relates to an epoxy tube for an optical fiber connector. The tube can be mounted to a ferrule hub by a snap fit connection. The connection between the tube and the ferrule hub allows for float of the epoxy tube where the epoxy tube is not rigidly attached to the hub. The epoxy tube can be configured to move about an arc of rotational circular movement while remaining linear such that the epoxy tube does not bend or transfer forces to the hub.

A cleaving mechanism (20) and related method is adapted to cleave an optical fiber (10) and thereby produce a cleaved end on the optical fiber. The cleaving mechanism (20) includes a fixture (40), a cleave tool (60) for cleaving the optical fiber, and a clamp assembly (80). The clamp assembly (80) may hold the optical fiber without substantial twisting of the optical fiber (10). The fixture and/or the clamp assembly (80) may include a pair of leaf springs (92) that contact and bend around the optical fiber (10) to secure the optical fiber (10) in a clamped position.

Provided is an optical connector used for connecting an optical waveguide substrate and an optical-fiber connector member, where the optical connector comprises a plurality of positioning structures, each having a cylindrical hole for inserting another end of a pin which has an end inserted into the connector member, and a groove formed on a second surface perpendicular to a first surface on which an open end of the hole is located, and where the groove and the hole are continuous, the groove has an arc-shaped cross section, and a center of a circle formed by a cross section of the hole and a center of an arc formed by the cross section of the groove are identical, and when the optical connector is coupled to the optical waveguide substrate that comprises a plurality of protrusions having a rectangular cross section, in each of the plurality of positioning structures, at least two corners of a corresponding protrusion among the plurality of protrusions are supported by an inner wall of the groove.

A gas detector sensor node includes a first sensor conductor having a terminal end, a second sensor conductor including an end section, and a coupler joining the terminal end of the first sensor conductor with the end section of the second sensor conductor. The coupler is permeable to gas.

An easily assembled SC connector, comprising a tail sleeve, an outer frame sleeve, a fixing piece, a limiting piece, a tail pipe, a stop ring, a press-inserting core tail shank, a spring, a metal ring, a ceramic inserting core, and a dustproof cap. During assembling, the tail pipe is sleeved in the tail sleeve in an interference fit, then the metal ring is fixedly connected to the press-inserting core tail shank by means of injection molding, and the stop ring and the limiting piece are fixed by means of injection molding. The injection molding has a simple production process and low costs. The whole assembly process is simple, and automatic assembly can be achieved. In addition, the present application only needs to directly extend a needle for dispensing glue into the center of the press-inserting core tail shank.
