摘要: An optical network includes interconnected via an N×N WDM router. The nodes are connected to an optical waveguide ring having a duplex structure. A first set of optical waveguides connects the transmitters in the nodes and a second set of optical waveguides connects the receivers in the nodes. The N×N wavelength router is connected across the ring between the first set of optical waveguides and the second set of optical waveguides. Each of the nodes is able to communicate with any other of the nodes on a respective wavelength channel via the router.

摘要: A peel-open package includes a polymeric film, a lid adhered to the polymeric film along a continuous portion thereof and a product encapsulated between the polymeric film and lid material. The polymeric film is typically a coextruded multiple layer film having a sealable layer and at least one base layer. The sealable layer comprises an ethylene copolymer derived from at least one monomer selected from the group consisting of vinyl acetate and alkylacrylates, a talc additive, and an additive which provides peelability to the heat seal layer. The lid material is preferably a microporous layer to allow sterilization and prevent subsequent contamination by bacteria and other microbial organisms. The peel-open package provides a good seal range for uncoated Tyvek.RTM., evidence of seal integrity, reduced Tinting, and a seal strength which is sufficiently low to prevent the delaminating or branching of the lid material when it is removed. The present invention also includes methods of making peel-open packages.
摘要翻译: 剥离开包装包括聚合物膜,沿其连续部分粘附到聚合物膜上的盖和封装在聚合物膜和盖材料之间的产品。 聚合物膜通常是具有可密封层和至少一个基底层的共挤出多层膜。 可密封层包含衍生自至少一种选自乙酸乙烯酯和丙烯酸烷基酯的单体的乙烯共聚物,滑石添加剂和向热封层提供可剥离性的添加剂。 盖材料优选是微孔层,以允许灭菌并防止随后的细菌和其它微生物的污染。 剥离开包装为未涂覆的Tyvek TM提供良好的密封范围,密封完整性的证据,减少的着色以及足够低的密封强度,以防止盖材料去除时的分层或分支。 本发明还包括制造剥离包装的方法。
