    Abstract: A cable (20) which may be used for communications, for example, include transmission media (24-24), each having a plastic composition of matter disposed thereabout. The insulation (26) comprises a polyvinyl chloride composition which includes a lubricant and a lead-free stabilization system. The stabilization system includes a calcium-zinc constituent in combination with an antioxidant-metal deactivator complex which provides a sacrificial function to prevent the formation of calcium or zinc chloride which would affect adversely the electrical properties of the insulated conductor. A jacket (28) typically is disposed about a plurality of the transmission media and comprises a non-lead stabilized plastic composition of matter.

    Abstract: A coating system for individual glass fibers of a lightwave communications system has improved strippability, particularly in situations where a group of such fibers are arrayed together in what is known as a ribbon. A preferred embodiment includes two layers (primary and secondary) of polymeric materials surrounding the glass fiber. The primary layer comprises an oligomer (50-80% by weight), a diluent (15-40% by weight), and additives (5-35% by weight). The oligomer comprises polyol "A," diisocyanate "B," and a hydroxy-terminated alkyl acrylate "C" having the structure C-B-A-B-C. At least one of the additives contains a non-crosslinked hydrocarbon component (1-20% by weight) having a structure R.sub.1 --(R).sub.n --R.sub.2 ; where R.sub.1, R.sub.2 comprises an alkyl group or an OH group, and R is a combination of C, H or C, H, O. In an alternative embodiment, the need for a diluent is substantially eliminated by using an oligomer having the structure E-D-E where "D" represents a carboxy-terminated polyol, and "E" represents a glycidyl acrylate.

    Abstract: A compact temperature compensating device for an optical fiber grating includes an inner expansion member disposed concentrically within and in a substantially parallel relationship with an outer expansion member. The outer expansion member has a coefficient of thermal expansion greater than that of the inner expansion member. The device further includes a base member and a pivoting lever. The base member is fixedly attached to a distal end of the outer and inner expansion members and to a distal end of the fiber grating disposed concentrically within the inner expansion member. The lever is connected to a proximal end of the inner and outer expansion members and to a proximal end of the fiber grating through joints that are flexurally deformable so that, as the expansion members expand and contract differentially within an expected temperature range, the lever pivots about the inner expansion member and imparts a desired amount of axial strain in the fiber grating to maintain the grating wavelength substantially constant.

    Abstract: Applicants have discovered that the speed of fiber manufacture can be substantially increased by employing a two-step curing process in which the fiber is drawn, coated and exposed to ultraviolet light on-line at high line speeds to effect a partial cure of the coating. After further cooling, the partially cured coating is fully cured by an on-reel exposure to ultraviolet light. The on-reel exposure can take place on the draw tower take-up reel as it is filing with fiber or it can take place off-line after the take-up reel has been filled and removed from the line. The on-reel exposure advantageously takes place either during filling the take-up reel, or during emptying the reel, so that each layer of fiber on the reel is exposed equally to the ultraviolet light. This method of UV illumination improves the energy efficiency in the second exposure by at least a factor of 10 to as much as a factor of 1000. The fiber primary coating pullout strength and mechanical modulus are enhanced.

    Abstract translation: 申请人已经发现，通过采用两步固化方法可以显着提高纤维制造的速度，其中纤维被拉伸，涂覆并以高线速度在线暴露于紫外线以使涂层部分固化。 在进一步冷却后，部分固化的涂层通过在线曝光的紫外线完全固化。 卷筒纸曝光可能发生在拉丝架卷取卷轴上，因为它是用纤维填充的，或者在卷取卷轴已经从线中取出后可以脱机进行。 卷取机曝光有利地在填充卷取卷筒期间或在排空卷轴期间进行，使得卷轴上的每层纤维均等地暴露于紫外光。 这种UV照射方法将第二次曝光中的能量效率提高至少10倍至高达1000倍。纤维初级涂层拉拔强度和机械模量提高。
