摘要： A cable block for telecommunications cable includes first and second half shell members which together form a substantially cylindrical stepped longitudinal bore therethrough, portions of the bore being sealingly engaged against progressive stripped outer parts of a stripped part of the cable so as to sealingly engage against each intermediate layer thereof which could form a water channel between its adjacent cable layer. Metal pins are also provided which extend into the channel and electrically connect to a ground shield of the cable for dissipating electrical currents during current surges as can occur when lightening strikes. The cable block is useable for terminating an end of a cable of an intermediate section thereof at which access to the telecommunications conduction media is required without breaking the conduction media.

摘要： A card cage for housing a plurality of circuit boards and passive optical fiber couplers contains a tray for storing express optical fibers or express optical fiber tubes not to be coupled within the card cage but rather expressly routed through a distribution point accommodating the card cage. The tray has a flexible hinge thereon and means for keeping the tray passively deflected away from the optical couplers for facilitating insertion and removal of optical fibers into and from the couplers. A card cage housing snap fits to a card cage base without requiring screws or other physically detachable elements. The housing also includes a plurality of flexible deflectable clips integrally molded as part of the card cage housing which normally keep the circuit cards or boards within the card cage housing but which are deflectable so as to allow the boards to be slideably inserted and removed from channels within the housing for guiding the boards. The card cage further includes a backplane from which a plurality of test pins extend externally from the card cage so as to allow an electrical integrity of the card cage to be easily tested.

摘要翻译： 用于容纳多个电路板和无源光纤耦合器的卡笼包含用于存储快速光纤的托盘或者表示不耦合在卡笼内的光纤管，而是明确地通过容纳卡笼的分配点布线。 托盘具有柔性铰链，并且用于保持托盘被动偏离光耦合器的装置，以便于将光纤插入耦合器和从耦合器移除光纤。 卡笼壳卡扣适合卡笼底座，而不需要螺丝或其他物理上可拆卸的元件。 壳体还包括多个柔性可偏转夹子，其整体模制成卡笼壳体的一部分，其通常将电路卡或板保持在卡笼壳体内，但是可偏转，以允许板可滑动地插入和移除通道 在用于引导板的壳体内。 卡笼还包括一个背板，多个测试针从该背板延伸到卡笼的外部，以便容易地测试卡笼的电气完整性。
