摘要： In accordance with the invention, an optical fiber is provided with a protective coating having enhanced thermal characteristics for easy removal from the optical fiber. In particular, at elevated temperatures used in stripping, the delamination resistance drops to low levels substantially independent of modulus. This permits fabrication of a protectively coated fiber which has relatively high modulus and delamination resistance at room temperature but, due to its enhanced thermal characteristics, is nonetheless relatively easy to strip at elevated temperatures. Thus, for example, applicants can provide a protectively coated optical fiber or ribbon with a room temperature modulus of at least 90 psi, and a high temperature delamination resistance that is less than 40% of the room-temperature delamination resistance and preferably less than 30%. Coatings based on a polyether backbone and non-polar monomers are preferred.
摘要翻译：根据本发明，光纤设置有具有增强的热特性的保护涂层，以便于从光纤中去除。特别地，在汽提中使用的升高的温度下，脱层性降低到基本上与模量无关的低水平。这允许制造在室温下具有相对高的模量和耐分层性的保护涂层的纤维，但是由于其增强的热特性，在高温下相对容易剥离。因此，例如，申请人可以提供具有至少90psi的室温模量的保护性涂覆的光纤或带，并且耐高温分层性小于室温耐层压性的40％，优选小于30 ％。优选基于聚醚主链和非极性单体的涂料。

摘要： An optical terminator 100 is designed to make end-to-end contact with an optical fiber whose end portion is held within a cylindrical ferrule. The optical terminator reduces reflections that occur when an optical path encounters an abrupt change in refractive index (e.g., when the end portion of the optical fiber encounters an air gap whose refractive index n.apprxeq.1.0). The optical terminator includes a generally cylindrical member 110 that projects from, and is supported by, a backbone member 120. The cylindrical member and the backbone member are molded from polymethyl methacrylate (PMMA) as a one-piece structure. PMMA provides a reflection of about -40 dB. Nevertheless, plastic materials having an index of refraction of 1.46.+-.0.06 produce reflections that are less than about -34 dB, which is acceptable in a large number of applications. Moreover, plastic materials having a glass-transition temperature (T.sub.g) that is higher than about 80.degree. C., exhibit minimum indentation creep under a compressive load at elevated temperatures. In one embodiment, the optical terminator 100 is spring loaded within a connector housing 45. In another embodiment, the spring 44 is eliminated and a connector housing is integrally molded with the optical terminator as a one-piece structure 70.

摘要： The specification describes a connector for joining optical elements, especially optical fibers. The connector is a sleeve made of a Simple Shaped Memory Polymer (SSMP) into which the optical fiber is inserted and the sleeve heated to collapse the sleeve around the optical fiber. The SSMP materials are not crosslinked and can be manufactured by a variety of techniques including extrusion. Various methods for forming the bore of the connector and expanding the size of the bore from the memory state to the metastable state are described.

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： An optical fiber [10] having protective coating materials [14, 15], which surround an elongated strand of glass [12], is designed for improved strippability. Preferably, the optical fiber includes two layers (primary and secondary) of radiation-cured polymeric materials surrounding the glass fiber. The primary layer has an equilibrium (in-situ) modulus that resides within the range 120 to 500 psi. Additionally, the primary coating has a pull-out force (adhesion) that is less than 1.2 pounds per centimeter of length (lb/cm), and preferably resides within the range 0.5 to 1.0 lb/cm. It has been found that by increasing the equilibrium modulus, delamination resistance is increased. This has allowed designers to decrease pull-out force while maintaining a suitable delamination resistance. As a result, coating materials can now be stripped away from a glass fiber with little or no residue. This is particularly important in situations where a group of such fibers are bound together in an array [20] by a matrix bonding material [21].
摘要翻译：具有保护涂层材料[14,15]的光纤[10]，其围绕细长的玻璃束[12]被设计用于改善剥离性。优选地，光纤包括围绕玻璃纤维的辐射固化的聚合材料的两层（初级和次级）。主层具有驻留在120至500psi范围内的平衡（原位）模量。此外，初级涂层具有小于1.2磅/厘米长（lb / cm）的拉出力（粘合），并且优选在0.5至1.0lb / cm的范围内。已经发现，通过增加平衡模量，增加了耐分层性。这使得设计人员能够在保持合适的抗分层性的同时降低拉出力。因此，涂层材料现在可以剥离玻璃纤维，很少或没有残留物。这在一组这样的纤维通过基体结合材料[21]以阵列[20]结合在一起的情况下尤其重要。

摘要： The present invention provides a method and apparatus for monitoring a UV curing lamp system to determine whether a UV-curable material passing through the curing lamp system is being properly cured. A thermal sensor is disposed to measure the temperature of gas being exhausted from a center tube of the UV curing lamp system. The center tube typically has nitrogen gas pumped into it to purge air from the center tube. The UV-curable material passes through the center tube. If a defect exists in the center tube, or if insufficient UV radiation is reaching the UV-curable material, the temperature of the gas stream exhausted from the center tube will drop. The temperature of the gas is compared to first and second threshold values, respectively, to determine whether a defect in the center tube exists or whether insufficient radiation is reaching the UV-curable material, respectively.
