摘要： A fiber optic coupler includes at least two optical fibers having a coupled region and at least one lead portion extending therefrom. The optical fibers have a protective jacket thereon. The protective jacket is removed from the coupled region and from a region of the at least one lead portion adjacent the coupled region resulting in a jacketless coupled region, at least one jacketless lead portion and at least one jacketed lead portion. The fiber optic coupler further includes a protective body having a receiving space therein for receiving the coupled region. The protective body has at least one entrance from which said jacketed lead portion emerges. A rejacket material at least partially surrounds a length of the jacketless lead portion adjacent the jacketed lead portion resulting in a rejacketed lead portion. An adhesive material at least partially about a length of the jacketed lead portion at the entrance and at least partially about the rejacketed lead portion secures the length of the jacketed lead portion and rejacketed lead portion to the protective body.

摘要： An optical fiber fusion splicer apparatus (20) comprises a laser power source that produces a laser beam (32) having a laser beam axis (26). The laser power source includes a laser (22), a shutter (28) that controllably blocks and passes the laser beam, and an optical system (30) that expands the diameter of the laser beam. A parabolic mirror (34) has its axis coincident with the laser beam axis (26) and a bore (48) therethrough coincident with the laser beam axis (26). Optical fiber clamps (42, 46) hold the two optical fibers (40, 44) with their axes coincident with the laser beam axis (26) and their ends (62, 64) at the focal point (38) of the parabolic mirror (34). A sensor (82) measures the power reaching the optical fiber ends (62, 64) at the focal point (38) of the parabolic mirror (34), and a controller (72) controls the power level of the laser (22) responsive to the power measured by the sensor. The alignment of the optical fibers (40, 44) is sensed, preferably by a reflective device (74) that measures their internal reflectance or a video camera (68) that images their peripheries, and the optical fiber ends (62, 64) are aligned responsively.

摘要： Fusion splicing of optical fiber generally requires removal of a polymer coating from the end portions of two lengths of fiber. A conventional removal method involves immersion of the fiber ends in an appropriate polymer stripping liquid, e.g., in hot, concentrated sulfuric acid. It is known that the strength of fusion splices generally is statistically distributed, such that there exists a probability that a given splice will pass at a given proof test level. We have found that the splice strength distribution can be shifted towards higher strength if the polymer stripping liquid comprises means for insuring that the liquid is essentially free of strength-reducing particles. Preferred means are concentrated nitric acid. Exemplarily, the liquid is at a temperature in the range 170.degree.-200.degree. C. and comprises concentrated (about 95%) sulfuric acid and about 5% b.v. concentrated (about 70%) nitric acid.

摘要： A heat recoverable article comprising a conductive polymeric material with particular electrical properties. Preferably, when expanded from X% to Y% to render it recoverable the resistivity of the composition decreases on expansion in at least part of the X-Y expansion range. Preferably the composition exhibits a pseudo PTC ratio (peak resistivity/resistivity at 25.degree. C.) in the range 11/2-10. Preferably the composition has a resistivity which increases on recovery as measured in the direction of current flow, throughout the temperature range 20.degree. C. to T.sub.e (extrapolated end temperature). The article is preferably tubular, and the electrtical behaviour allows it to be conveniently electroded with elongate electrodes, while avoiding overheating during recovery.

摘要： A tubular heat recoverable article comprises conductive polymeric material and is heated to effect recovery by the passage of electrical current therethrough. Elongate electrodes are attached on the surface or embedded in longitudinal flanges extending along the article. The flanges also comprise conductive polymeric material but are not heat recoverable, and therefore remain substantially undeformed on recovery other than bending to accommodate transitions. This means that the contact resistance between the electrode and the conductive material of the flange does not increase significantly on recovery.

摘要： Spliced end portions (30--30) of two optical fibers are recoated in a manner which results in the cross section of the spliced length of fiber transverse to a longitudinal axis thereof being substantially constant. This is accomplished without compromising the adhesion of a curable recoating material (51) to an adjacent original coating material (38). In order to provide such a recoated portion, original coating material which is removed to permit splicing is removed in such a manner as to leave a tapered portion (52) remaining on the end portion of each optical fiber. As a result, the interface between the recoating material and the original coating material is increased sufficiently to avoid having to overlap some of the recoating material with original coating material on adjacent portions of the fibers being spliced. Further, the spliced, recoated end portions are positioned at the focal point of a parabolic reflective surface (75) so that a portion of the radiation which is emitted toward the spliced end portions to cure the recoating material is reflected to engage non-exposed peripheral portions of the recoating material to insure uniformity of cure.
摘要翻译：以这样一种方式对两根光纤的接合端部（30-30）进行重新涂覆，其结果是横向于其纵轴的纤维的拼接长度的横截面基本上是恒定的。这是在不损害可固化重涂材料（51）与相邻的原始涂层材料（38）的粘附的情况下完成的。为了提供这样的重涂部分，去除被去除以允许接合的原始涂层材料以使得留在每个光纤的端部上的锥形部分（52）的方式被去除。结果，重新涂覆材料与原始涂层材料之间的界面被充分地增加，以避免必须将一些重涂材料与原始涂覆材料重叠在被拼接的纤维的相邻部分上。此外，拼接的重新涂覆的端部位于抛物面反射表面（75）的焦点处，使得朝向拼接端部发射以固化重涂材料的辐射的一部分被反射以接合未暴露的外围重涂材料的一部分以确保固化的均匀性。

摘要： Two optical fibers are spliced together to form a single spliced optical fiber. The spliced region is uncontaminated by impurities, and has substantially no loss of optical transmission or mechanical strength as compared to the other regions of the fibers. Splicing is accomplished by removal of the buffer coating, if any, cleaving of the fibers to be spliced to form facing splicing surfaces, careful precleaning of the cleaved fibers in the region adjacent the splicing surfaces, aligning the fibers using optical transmission as the alignment criterion, fusing the fibers together by preheating the region to be spliced, fusing the region, postannealing the spliced region, carefully postcleaning the spliced region, and recoating the spliced region with a UV curable polymer buffer material, if desired. The heating of the fibers to accomplish the fusion is desirably accomplished by a laser such as a carbon dioxide laser.

摘要： An in-line splice case assembly includes a pair of end plugs exhibiting axially disposed apertures for mating optical fibers and fiber wands associated therewith. A pair of elongated, rigid torque bars join the end plugs and support at least one, but preferably two, rotatably attached, resilient clips, the clips for securing appropriate elastomeric fiber splices. A substantially cylindrical housing encloses the end plugs, the torque bars, and the clips. The housing exhibits an interior surface having threaded portions at opposite ends thereof, complementary to threaded portions of a pair of end caps threaded thereinto.
