摘要： An assembly capable of enclosing and sealing an intermediate section of an optical fiber includes a plurality of sealing mechanisms arranged such that the assembly can be entered to gain access to electronic components for servicing without affecting an environment occupied by optical fiber broken out of an optical fiber cable. Accordingly, physical integrity of the exposed fiber, and its associated connectors and splices, is not compromised. The assembly further includes a plurality of card cages, each of which has its own integral backplane having socket connectors which allow for connection to an adjacent card cage backplane within the assembly. During initial deployment of the assembly where less than all card cages for maximum capacity are initially required to be deployed, segmenting the backplane reduces the first installed cost of the assembly. Finally, multiple alarms are provided for the assembly to alert a central office that a cover of the assembly has been removed and a humidity level within a vicinity of the broken out fiber cable exceeds a predetermined level.
摘要翻译：能够封闭和密封光纤的中间部分的组件包括多个密封机构，其布置成使得可以进入组件以进入用于维修的电子部件，而不会影响由光纤断开的光纤所占据的环境电缆。因此，暴露的光纤及其相关联的连接器和接头的物理完整性不受影响。组件还包括多个卡笼，每个卡笼具有其自己的整体底板，其具有插座连接器，其允许连接到组件内的相邻卡笼背板。在组装的初始部署期间，最初需要部署最少容量的所有卡笼时，分割背板会降低组件的首次安装成本。最后，为组件提供多个报警，以警示中心局组件的盖已被移除，并且断裂的光纤电缆附近的湿度水平超过预定水平。

摘要： An optical fiber enclosure for a pedestal environment includes a pedestal which slideably supports a closure within the pedestal along a vertical direction so that during freeze-thaw envionrmental conditions when the pedestal is raised and lowered by expanding and contracting earth the closure does not impose undue stress on optical fiber cables connected thereto. Another enclosure suitable for buried applications also includes means for slideably extending an inner closure therefrom along a vertical direction to aid a craftsperson in accessing and working on the inner closure, the buried enclosure including means for allowing one or more loops of telecommunications cable to be stored therewithin for allowing the inner closure to be removed a substantial distance therefrom.
摘要翻译：用于基座环境的光纤外壳包括可沿着垂直方向可滑动地支撑基座内的封闭件的基座，使得在通过膨胀和收缩接地将基座升高和降低时的冻融环境条件下，封闭件不会施加过度的应力连接在其上的光纤电缆。适用于埋藏应用的另一个外壳还包括用于沿着垂直方向从其上滑动地延伸内部封闭件的装置，以帮助工匠进入内部盖子并进行工作，所述埋入式外壳包括用于容纳电信电缆的一个或多个环路的装置其中允许内盖从其中移除相当大的距离。

摘要： A utility knife has a handle and a replaceable blade fixed to the handle. The blade has a cutting edge extending from the handle along an axis for a distance. The utility knife includes a movement mechanism, which may be at least partially enclosed by the handle. The movement mechanism is adapted to provide reversible motion along relative to the blade. A shield is connected to the movement mechanism and disposed adjacent to the blade, whereby the shield is movable between an extended position covering the cutting edge and a retracted position exposing the cutting edge. When in a retracted position, the shield may be inside or closely adjacent to the handle, so as to not interfere with handling of the knife.
摘要翻译：实用刀具有固定在手柄上的手柄和可更换刀片。刀片具有从手柄沿轴线延伸一段距离的切割刃。该实用刀包括一可移动机构，该机构可至少部分地由手柄包围。移动机构适于提供相对于叶片的可逆运动。屏蔽件连接到移动机构并且设置成与叶片相邻，由此屏蔽件可以在覆盖切割边缘的延伸位置和暴露切割边缘的缩回位置之间移动。当处于缩回位置时，屏蔽件可以在手柄的内部或紧邻的位置，以便不干扰刀具的处理。
