摘要： An optical connector assembly includes a connector body having an inner wall defining a bore extending longitudinally through the connector body and shaped to receive an optical fiber. A fiber-retaining mechanism is disposed in the connector body for retention of the optical fiber received in the bore by frictionally engaging an outer circumferential surface of the optical fiber to thereby restrain unintended longitudinal displacement of the optical fiber relative to the bore.

摘要： A temperature compensating optical waveguide device including an optical fiber in which a grating formed of grating elements embedded within the fiber core reflects fiber-transmitted light within a range about a central wavelength that varies with temperature and with an axial strain applied to the grating. A top surface of a compensating member is affixed to a portion of the fiber that includes the grating and a tension adjusting member is connected to the compensating member. The tension adjusting member and the compensating member are formed of materials selected so that as the temperature of the device decreases, the tension adjusting member contracts more than the compensating member so as to control the deformation of the compensating member and thereby impose an axial strain on the grating. The controlled application of tensile stress to the optical fiber in the region of the grating causes changes in the central wavelength of reflected light to compensate for central wavelength variations resulting from changes in the grating temperature.

摘要： An optical fiber connection device is disclosed that allows for in situ variable attenuation of a signal transmitted between two optical fibers. The connection device comprises an attenuator element fabricated with an inherently compliant, elastomeric material, preferably a silicone elastomer. The elastomeric properties of the attenuator element allow for varying the thickness of the attenuator element and thereby changing the level of attenuation in situ. Silicone elastomers are preferred for fabricating the attenuator element as applicants have discovered they may be index-matched to optical transmission fibers, have a high creep modulus, exhibit relatively constant mechanical properties over a broad range of temperatures, and are reliable upon exposure to varied environmental conditions.

摘要： A method and apparatus for manufacturing an optical connector subassembly provide an improved device at lower cost. The optical connector includes a plastic base member 150 which is overmolded onto a cylindrical ferrule 140 having an axial passageway 145 which extends from one end face 141 of the ferrule to the other 142. A mold 900 includes two parts 910, 960 which are joined together before heated and pressurized thermoplastic material is injected. The ferrule is held within a first channel 914 of the mold and a spring-loaded core pin 950 is held within a second channel 964 of the mold. These channels are coaxially aligned when the mold parts are joined together. The core pin includes a conical point 951 at one end which enters the axial passageway of the ferrule before the thermoplastic material is injected. A third channel 912, 962 receives the thermoplastic material and routes it into the first and second channels. Moreover, a brake 970 is applied to the core pin when thermoplastic material enters a fourth channel 913 so that the conical point will remain in contact with end face 141 of the ferrule during molding.

摘要： A fitting for a fluid-conveying conduit. The fitting includes integrally-formed clamps that can be used to secure the conduit in a locking relationship so that likelihood of leakage and separation of the fitting and the conduit is reduced. In one form, the fitting and conduit can be used as a moisture exchange device. In a more particular form, the conduit wall of the moisture exchange device includes a water-permeable material such that a humidity level in the conduit can be controlled. Since the fitting is formed separately from the end of the conduit to which it is to be attached, fabrication cost and complexity is reduced.

摘要： The invention relates to plastic optical fiber (POF) processes and systems and involves improved non-polishing termination techniques. The techniques provide good physical and optical characteristics, i.e., smoothness, at the termination point, thereby providing lower losses than conventionally obtained. According to one embodiment, POF is cut while the fiber is under compression. According to another embodiment, the POF is notched and then pulled at a relatively high strain rate to induce fracture. The rate is such that the strain remains in the elastic region, i.e., the fiber exhibits brittle, as opposed to ductile, behavior during the strain. The brittle behavior provides a smooth termination surface, as opposed to a plastically-deformed surface.
摘要翻译： 本发明涉及塑料光纤（POF）工艺和系统，涉及改进的非抛光终止技术。 这些技术在终止点提供良好的物理和光学特性，即平滑度，从而提供比传统获得的更低的损失。 根据一个实施例，当纤维处于压缩状态时，切割POF。 根据另一实施例，POF被切口，然后以相对高的应变速率拉动以引起断裂。 速率使得应变保持在弹性区域中，即纤维表现出脆性，与在应变期间的延展性行为相反。 与塑性变形的表面相反，脆性行为提供了平滑的终止表面。

摘要： A tube take-up apparatus is provided to handle a length of freshly extruded tube. The apparatus includes an elongated housing in which a pair of parallel, spaced-apart rollers extend lengthwise in a position just below the extruded tubing. The housing is removably mounted on an elongated supporting fin which is secured to the extruder at its near end, extends upwardly between the two rollers and substantially along the entire length of the housing, and is, in turn, supported on a fixed pedestal at its remote end. After the full length of tubing has been extruded, the housing and rollers as a unit are lifted with the tube from the supporting fin and replaced by an empty housing, to extrude the next tube, while the full housing is carried away to a dryer.

摘要： A fragile device, such as an integrated circuit chip or a multichip assembly, is packaged by first dispensing a sol surrounding the sides of the device. The sol is laterally confined by means of a rim member typically made of a pre-molded plastic material. The amount of the sol dispensed is not sufficient to run over the top of the rim member. The sol is then heated to form a gel. If desired, a cover member can be put into place onto the top surface of the rim member, for the purpose of additional mechanical protection of the fragile device, for example.

摘要： The specification describes a molded plastic package for a surface normal optoelectronic device. The package is designed to passively align precisely the optoelectronic device with an optical fiber. Passive alignment is achieved by forming the optoelectronic device in a pyramid shape, and forming an identical pyramid shape in a mating molded plastic cover for the device. The mating pyramid shapes serve to center the optical fiber core precisely over the active optical region of the surface normal optoelectronic device.
