摘要	The invention relates to high-strength, abrasion-resistant optical fiber cable having a supplemental layer consisting essentially of a liquid crystal polymer (LCP) to enhance the cable's tensile strength and hermetically seal it, and an outermost encasing layer to protect the LCP supplemental layer from damage that could otherwise diminish the tensile strength or destroy the moisture barrier properties of the cable gained by adding the supplemental liquid crystal polymer layer. The encasing layer is preferably a thin layer of a smooth, non-crystalline thermoplastic that can be easily removed with chemicals that do not affect the properties of the supplemental layer so that the supplemental layer can be made accessible for promoting the formation of hermetically sealed interfaces between the cable and other structures. Cross-head extrusion methods for coating optical fibers with LCP and encasing layers are described along with laser and ultrasonic bonding techniques for fabricating hermetic packages.
其他摘要	本发明涉及高强度，耐磨的光纤电缆，其具有补充层，该补充层基本上由液晶聚合物（LCP）组成，以增强电缆的拉伸强度并密封它，以及最外层的外壳层，以保护LCP补充层。通过添加补充的液晶聚合物层，可以降低拉伸强度或破坏电缆的防潮性能。包封层优选是光滑的非结晶热塑性塑料的薄层，其可以用不影响补充层性质的化学品容易地除去，使得可以使补充层易于接触以促进气密密封界面的形成。电缆和其他结构之间。描述了用于利用LCP和包覆层涂覆光纤的十字头挤出方法以及用于制造密封包装的激光和超声波粘合技术。
