技术领域
本发明中的技术涉及用于室内应用,尤其是用于多住户单元中的光纤分配网络解决方案。该光纤网络解决方案可以包括一种转变盒,所述转变盒提供终端和散存储点,用于将垂直敷设的直立电缆转变为引入电缆,所述引入电缆用于对多住户单元的分配层上的多个用户进行馈电;以及用于将垂直敷设的直立电缆转变为分配电缆,所述分配电缆通过MDU的低层处的局部会聚点而光学连接到馈电电缆。
背景技术
当今世界对宽带带宽的需求不断增加,光缆已经成为电信网络的主要部分。光缆可以用非常快的速度在非常长的距离中传输语音信号、数据信号以及视频信号。因光电信网络的发展,终端用户可以被直接连接到光纤。称为FTTH技术(光纤到户)的此类网络技术要求“全光式”通信网络延伸到更接近订户。因此,此类电信网络包括从分配电缆到终端用户或订户的大量分配点。
FTTH网络中一个关键部分是通常为室内安装的最后一英里连接。像多住户单元和公寓这样的不同建筑物需要复杂的电缆系统,这可能意味着会有许多单独的电缆,每个电缆连接一个订户。安装许多电缆来连接主要分配点(通常位于建筑物的地下室或另一地点)与终端用户,这会由于路由穿过建筑物的墙壁或各层而导致许多问题。因此,此类安装会消耗大量时间和成本。

在另一项实施例中,揭示了一种用于多分配单元(MDU)的光纤网络中的转变盒,所述转变盒包括外壳以及以可移除方式安装在所述外壳中的模块。光纤适配器组件可枢转地安装在所述模块中。所述光纤适配器组件具有至少一个多芯光纤适配器以及至少一个单芯光纤适配器。直立电缆光学连接到所述光纤适配器组件,以向订户驻地提供光通信服务。以可移除方式安装在所述外壳内的牵出线轴,对牵出而延伸到MDU中一个或多个分配层中至少一层处的直立电缆的散堆进行存储。

具体实施方式
在详细说明中揭示的实施例包括用于多层的多住户单元(MDU)的光纤分配网络。所述网络包括可以位于地下室等MDU低层的局部会聚点(LCP)。所述LCP收纳馈电电缆,所述馈电电缆从服务供应商向MDU提供光通信服务。一个或多个预连接的直立电缆的每个末端上具有多芯光纤连接器,这些直立电缆通过所述LCP光学连接到所述馈电电缆。所述直立电缆从所述LCP延伸到MDU的一个或多个上分配层。在分配层中,直立电缆由网络接入点收纳,所述接入点可以由光纤分配终端(FDT)、中跨接入点等组成。为了本文的目的,术语网络接入点可以用于描述FDT和中跨接入点中的一者或多者。此外,应理解,术语FDT、管中盒以及壁橱盒将用于指代和描述位于分配层中的光纤分配网络中的部件,该部件用于将直立电缆光学连接到引入电缆。术语接插板外壳将用于描述光纤分配网络中用于将直立电缆光学连接并且延伸到LCP从而连接到馈电电缆的部件。
将直立电缆光学连接到订户驻地可以通过从直立电缆中分叉出来的系绳电缆来实现,分叉处位于每个分配层,例如在直立电缆的中跨接入点处。系绳电缆可以在网络接入点处经由一个或多个引入电缆而连接到订户驻地。作为替代或补充,单独的直立电缆可以延伸到分配层并且光学连接到路由至订户驻地的一个或多个引入电缆。在这种情况下,系绳电缆不会在中跨接入点处从直立电缆分叉出来。引入电缆延伸到分配层中的订户驻地,从而向订户提供光通信服务。任何直立电缆散堆都可以存储在FDT、接插板外壳,以及/或者单独的散堆外壳中。此外,所述直立电缆散堆可以存储在牵出线轴上,而牵出线轴以可移除方式安装在FDT、接插板外壳,或散堆外壳中。所述散堆外壳可以位于LCP处或其附近或者位于一个或多个分配层中。
直立电缆的末端可以光学连接到一个或多个引入电缆的末端。在任何情况下,系绳电缆和/或直立电缆都可以端接在光纤连接器中,并且可以通过合适的光纤适配器而光学连接到端接在光纤连接器中的引入电缆。所述光纤适配器可以是向多芯光纤连接器互连提供多芯光纤连接器的适配器,例如,MTP适配器,或其他类型的多芯光纤适配器。作为补充或替代,所述光纤适配器可以是向单芯光纤连接器互连提供单芯光纤连接器的适配器,例如,SC适配器,或其他类型的单芯光纤适配器。光纤适配器可以具有双快门,在适配器的每端各有一个。所述快门适于在光纤连接器未插入到适配器的一端时,自动地关闭适配器的该端。这样,这些快门可以密封适配器以隔绝环境,从而在不使用时保护适配器并使之保持清洁。所述适配器可以上下按动,以与连接器的极性保持协调。这些适配器可以安装在以可移除方式安装在网络接入点中的匣或模块中。或者,适配器可以以可移除方式安装在面板上,所述面板可以以可移除方式安装在网络接入点中。
这样,FDT和/或接插板外壳可以充当或可以是具有一个或多个以可移除方式安装的光纤适配器的转变盒,所述光纤适配器经配置以收纳直立电缆的一根或多根光纤,从而从服务供应商向订户驻地提供光通信服务。此外,所述转变盒具有一个或多个以可移除方式安装的牵出线轴,所述牵出线轴用于存储牵出到MDU中的直立电缆的散堆或多个电缆。
在这点上,图1到图6所示为MDU10中的光纤网络的示例性实施例。图1为MDU10的立体透视示意图,其中安装了示例性光纤网络12。带有预设中跨接入点16的直立电缆14从牵出线轴18延伸出去。中跨接入点16可以包括康宁电缆系统LLC(Corning Cable SystemsLLC)市售的FlexNAP系统,或用于将一根或多根光纤从直立电缆14分离出来的其他类型的连接或系统。直立电缆14从牵出线轴18牵出。一旦直立电缆14从牵出线轴18牵出而到达多个分配层24、26、28,牵出线轴18便被可移除地安装到接插板外壳20中。尽管在图1中示出了三个高层24、26、28,但是光纤网络12可以具有任何数量的分配层。直立电缆14在直立电缆14的每个末端处与多芯光纤连接器30、32预连接。接插板外壳20具有多芯光纤到多芯光纤适配器组件34,该组件收纳第一多芯光纤连接器30。分配电缆36与多芯光纤连接器38预连接,该分配电缆由接插板外壳20中的多芯光纤适配器组件34收纳并且与之连接,从而建立了直立电缆14与分配电缆36之间的光连接。分配电缆36路由到局部会聚点(LCP)40。LCP40收纳馈电电缆42,所述馈电电缆从服务供应商向MDU10提供光通信服务。
在安装过程中,直立电缆14从牵出线轴18牵出,这样直立电缆14大体在向上的方向上从低层22延伸到每个向上的分配层24、26,接着延伸到为MDU10中最高分配层的分配层28。中跨接入点16经预设使得它们沿着直立电缆14的长度分开距离“X”。距离“X”在工厂预设为某一值,该值取决于相邻的分配层24、26之间的距离。例如,距离“X”可以设置为任何所需距离,例如,10英尺、12英尺、14英尺、15英尺等。这样,随着直立电缆14牵出并且安装在MDU10中,预设的中跨接入点将大体与MDU10中的各分配层24、26、28对准。然而,此时一种例外情况可以是最高的分配层28,因为直立电缆14的末端会延伸到该层但可能不会具有中跨接入点。由于预设了距离“X”或其他情况的原因,任何直立电缆14的散堆都可以存储在接插板外壳20和/或散堆外壳(图1中未图示)中的牵出线轴18上。散堆还可以松散地存储在低层22处,以及/或者存储在位于分配层24、26、28中的一层或多层处的一个或多个光纤分配终端29中。此外,牵出线轴18可以以可移除方式安装在散堆外壳中或可以经安装或经定位以与接插板外壳20和/或散堆外壳以及/或者与分配层24、26、28中的一层或多层处的FDT29分开。
直立电缆14可以具有任何数量的光纤,作为非限制性实例,6到216根光纤。在每个中跨接入点16处,某些光纤可以在位于分配层24、26中的FDT29中从直立电缆14分离或分叉出来。作为非限制性实例,6、8或12根光纤可以从直立电缆14分叉出并且与第二多芯光纤连接器32端接。在最高分配层28,在低分配层24、26处分叉出一些光纤之后,直立电缆14中剩余的光纤与第二多芯光纤连接器32端接。第二多芯光纤连接器32可以由以可移除方式安装在分配层24、26、28中的FDT29中的多芯光纤适配器组件34来收纳。多芯光纤适配器组件34可以以可移除方式安装在连接器模块中(图1中未图示),所述连接器模块可以以可移除方式安装在FDT29中。
多芯光纤捆绑式引入电缆44与多芯光纤连接器38预连接,根据具体情况,该电缆由多芯光纤适配器组件34或连接器模块收纳并且与之连接,所述组件或模块位于分配线轴24、26、28中的FDT29中。这样便在直立电缆14与多芯光纤捆绑式引入电缆44之间建立了光连接。多芯光纤捆绑式引入电缆44路由到一个或多个引入盒46,所述引入盒与位于分配层24、26、28中的订户驻地48相连。一根或多根光纤在引入盒46处从多芯光纤捆绑式引入电缆44分离出并且延伸到订户驻地48。这样,光通信服务便被提供至订户驻地48。
作为替代或补充,一个或多个连接的线束可以在多芯光纤适配器组件34中的多芯光纤适配器之间连接并且延伸到单芯光纤适配器(图1中未图示)。在这种情况下,连接的单芯光纤引入电缆可以连接到这些线束以建立与直立电缆14之间的光连接,并且最终到达订户驻地48。
图2为MDU10的立体透视示意图,其中安装了示例性光纤网络112。具有预设中跨接入点16的直立电缆14从位于最高分配层28处的单独散堆外壳50中的牵出线轴18延伸到其他分配层24、26和低层22。光纤网络112类似于图1中所示的光纤网络12,因此,光纤网络112中参照图1所描述的各方面和/或各部件将不再参照图2进行描述。在图2中,在直立电缆14牵出之后,牵出线轴18以可移除方式安装在位于最高层28的散堆外壳50中,而不是安装在接插板外壳20中。这样,在安装过程中,直立电缆14从牵出线轴18中牵出,使得直立电缆14大体在向下的方向上从最高层28连续延伸到向下的分配层24、26,并且到达接插板外壳20。
接插板外壳20包括多芯光纤适配器组件34但是可能不包括牵出线轴18,因为所述牵出线轴位于光纤网络112中的最高分配层28。然而,接插板外壳20中的多芯光纤适配器组件34收纳第一多芯光纤连接器30并且将第一多芯光纤连接器与分配电缆36中的多芯光纤连接器38光学连接起来,从而建立了直立电缆14与分配电缆36之间的光连接,如上文参照图1所描述。
图3为MDU10的立体透视示意图,其中安装了示例性光纤网络212。具有预设中跨接入点16的直立电缆14从位于最高分配层28的FDT29中的牵出线轴18延伸到其他分配层24、26。光纤网络212类似于图1中所示的光纤网络12和图2中所示的光纤网络112,因此,光纤网络212中参照图1和/或图2所描述的各方面和/或各部件将不再参照图3进行描述。在图3中,在直立电缆14牵出之后,牵出线轴18以可移除方式安装在位于最高层28的FDT29中,而不是安装在散堆外壳50中,如参照图2所描述。这样,在最高层28处无需散堆外壳50,从而节约了空间。直立电缆14的牵出和安装可以与参照图2所描述的相同。
图4为MDU10的立体透视示意图,其中安装了示例性光纤网络312。多个直立电缆14(1)、14(2)、14(3)从接插板外壳20中的单独的牵出线轴18(1)、18(2)、18(3)延伸出去并且延伸到各个分配层24、26、28。每个直立电缆14(1)、14(2)、14(3)从各自的牵出线轴18(1)、18(2)、18(3)牵出。在直立电缆14(1)、14(2)、14(3)牵出之后,各个牵出线轴18(1)、18(2)、18(3)以可移除方式安装在接插板外壳20中。直立电缆14(1)、14(2)、14(3)大体在向上的方向上从低层22延伸到各个向上的分配层24、26、28。这样,单独的直立电缆14向各个分配层24、26、28提供光服务。直立电缆14(1)、14(2)、14(3)中的每一者都与各自的第二多芯光纤连接器32端接,所述第二多芯光纤连接器由位于分配层24、26、28处的FDT29中的各自多芯光纤适配器组件34收纳并且与之连接。在接插板外壳20中,直立电缆14(1)、14(2)、14(3)从牵出线轴18(1)、18(2)、18(3)中的每一者延伸到位于接插板外壳20处的多芯光纤适配器组件34。各个直立电缆14(1)、14(2)、14(3)中的第一多芯光纤连接器30由接插板外壳20中的多芯光纤适配器组件34收纳并且与之连接。分配电缆36与多芯光纤连接器38预连接,所述分配电缆由接插板外壳20中的多芯光纤适配器组件34收纳并且与之连接,从而建立了直立电缆14(1)、14(2)、14(3)与分配电缆36之间的光连接。分配电缆36路由至LCP40。
图5为MDU10的立体透视示意图,其中安装了示例性光纤网络412。多个直立电缆14(1)、14(2)、14(3)各从位于分配层24、26、28中一层上的各个单独的FDT29延伸到接插板外壳20。光纤网络412类似于图4中所示的光纤网络312,因此,光纤网络312中参照关于图4描述的各方面和/或各部件将不再参照图5进行描述。每个直立电缆14(1)、14(2)、14(3)从各自的牵出线轴18(1)、18(2)、18(3)牵出。在直立电缆14(1)、14(2)、14(3)被牵出到必要长度之后,牵出线轴18(1)、18(2)、18(3)以可移除方式安装在位于各个分配层24、26、28处的各个单独的FDT29中。直立电缆14(1)、14(2)、14(3)大体在向下的方向上从位于各个分配层24、26、28处的各个FDT29延伸到低层22。这样,单独的直立电缆14向各个分配层24、26、28提供光服务。直立电缆14(1)、14(2)、14(3)中的每一者都与各自的第二多芯光纤连接器32(1)、32(2)、32(3)端接,所述第二多芯光纤连接器由位于分配层24、26、28的FDT29中的各自多芯光纤适配器组件34收纳并且与之连接。在接插板外壳20中,每个直立电缆14(1)、14(2)、14(3)中的第一多芯光纤连接器30(1)、30(2)、30(3)由接插板外壳20中的多芯光纤适配器组件34收纳并且与之连接。分配电缆36与多芯光纤连接器38预连接,所述分配电缆由接插板外壳20中的多芯光纤适配器组件34收纳并且与之连接,从而建立了直立电缆14(1)、14(2)、14(3)与分配电缆36之间的光连接。分配电缆36路由至LCP40。
现参考图6,示出了光纤网络12、112、212、312、412中位于分配层24、26、28中的部分。多芯光纤捆绑式引入电缆44从分配层24、26、28中的FDT29延伸到与订户驻地48相连且位于该订户驻地处的引入盒46。多芯光纤捆绑式引入电缆44包括由一个或多个螺旋缠绕形的外部扎捆物54固持在一起的多个光纤电缆52。通过将所述多个光纤电缆从所述一个或多个外部扎捆物的固持状态中移除,所述多个光纤电缆中的一个或多个电缆会从多芯光纤捆绑式引入电缆44中分离出来。这样,单独的光纤电缆52可以延伸到订户驻地48。
图7为具有多个预连接的直立电缆14(1)、14(2)、14(3)的示例性预连接的直立电缆安装组件56的立体示意图,所述多个预连接的直立电缆通过在引线58的预设位置附接有延伸特征60的引线58而从位于低层22的各自牵出线轴18(1)、18(2)、18(3)延伸出去,所述预设位置沿着引线58长度相隔距离“Y”。所述延伸特征60可以是任何类型的环、钩、旋转接头等,所述环、钩、旋转接头等经配置以附接到第二多芯光纤连接器32(1)、32(2)、32(3)或附接到某一类型的牵引装置,所述牵引装置附接到第二多芯光纤连接器32(1)、32(2)、32(3),从而使直立电缆14(1)、14(2)、14(3)安全有效地牵出。
图7A为牵引装置组件62的细节图,所述牵引装置组件可以附接到直立电缆14的末端以帮助直立电缆14从牵出线轴18延伸出去。牵引装置组件62围绕着第二多芯光纤连接器32附接到直立电缆14,从而罩住第二多芯光纤连接器32、引出罩(boot)以及直立电缆14的一部分。牵引装置组件62具有旋转接头端64和主体66。主体66可以罩住并且/或者支撑第二多芯光纤连接器32。旋转接头端64可以自由地旋转并且独立于主体66旋转,从而可以独立于第二多芯光纤连接器32和直立电缆14旋转。旋转接头端64包括孔,所述延伸特征60穿过该孔插入。随着使用附接到引线58末端的牵引环68以及附接到旋转接头端64的延伸特征60而将直立电缆14牵引穿过MDU10,确切地说是在管道中进行牵引,旋转接头端64可以独立于牵引装置组件62的其余部分而旋转。该独立旋转消除了直立电缆14与第二多芯光纤连接器32发生缠绕的情况。这样,随着引线58牵引穿过MDU10,确切地说是在管道中进行牵引,引线58、延伸特征60和旋转接头端64便减少或可以消除在直立电缆14和/或第二多芯光纤连接器32上产生任何额外的扭应力。
再次参考图7,距离“Y”预设为某一值,该值取决于相邻分配层24、26、28之间的距离。例如,距离“Y”可以设置为10英尺、12英尺、14英尺、15英尺等。这样,随着引线58牵引穿过MDU10,直立电缆14(1)、14(2)、14(3)各自牵出到一个点,该点大体与MDU10中的各个分配层24、26、28对准。由于预设了距离“Y”或其他情况的原因,任何直立电缆14的散堆都可以存储在各自牵出线轴18(1)、18(2)、18(3)上和/或松散地存储在接插板外壳20和/或散堆外壳(图7中未图示)中。此外,散堆可以松散地存储在牵出线轴18(1)、18(2)、18(3)和/或分配层24、26、28中的一层或多层处的FDT29上。各个第二多芯光纤连接器32(1)、32(2)、32(3)随后可以连接到以可移除方式安装在位于各个分配层24、26、28处的FDT29中的各自多芯光纤适配器组件34。此外,附接到各自直立电缆14(1)、14(2)、14(3)的第一多芯光纤连接器30(1)、30(2)、30(3)可以连接到以可移除方式安装在接插板外壳20中的各自多芯光纤适配器组件34。

距离“Z”预设为某一值,作为非限制性实例,6英寸,从而使引线58可以按降序在每个相继的分配层24、26、28处接入,从而将延伸特征60附接到特定的直立电缆14(1)、14(2)、14(3)。换句话说,用于最高分配层28的直立电缆14(3)首先附接到引线。随后,用于随后的下一低分配层26的直立电缆14(2)附接到引线58。随后,用于下一低分配层24的直立电缆14(1)附接到引线58。引线58延伸到低层22。任何直立电缆14的散堆可以存储在各个牵出线轴18(1)、18(2)、18(3)上以及/或者松散地存储在分配层24、26、28处的FDT29和/或散堆外壳(图9中未示出)中。此外,散堆可以存储在接插板外壳20中。各个第二多芯光纤连接器32(1)、32(2)、32(3)随后可以连接到以可移除方式安装在位于各个分配层24、26、28处的FDT29中的各自多芯光纤适配器组件34。此外,附接到各个直立电缆14(1)、14(2)、14(3)的第一多芯光纤连接器30(1)、30(2)、30(3)可以连接到以可移除方式安装在接插板外壳20中的各自多芯光纤适配器组件34。
图10为根据一项示例性实施例的多个预连接的直立电缆14(1)、14(2)、14(3)从位于MDU10中分配层24、26、28处的牵出线轴18(1)、18(2)、18(3)到接插板外壳20的安装方法的流程图。将每个牵出线轴14(1)、14(2)、14(3)定位在各自分配层24、26、28中(步骤2000)。可选地,可以将牵引装置组件62附接到各个直立电缆14(1)、14(2)、14(3)的末端(步骤2002)。提供具有延伸特征60的引线58,所述延伸特征定位成沿着引线58的长度相隔预设距离“Z”(步骤2004)。将牵引绳在引线58的末端处附接到牵引环68(步骤2006)。将延伸特征60中的一个(可以是最靠近牵引环68的第一延伸特征60)附接到从位于MDU10中最高分配层28处的牵出线轴18(3)牵出的直立电缆14(3)(步骤2008)。将引线58按降序延伸到下一个相继的分配层26、24(步骤2010)。在下一个相继的分配层26、24,接入引线58并且将下一个延伸特征60附接到此直立电缆14(2)、14(3)的末端(步骤2012)。引线58延伸到所有的分配层并且直立电缆用相同的方式附接。将引线58延伸到低层22(步骤2014)。将直立电缆14(1)、14(2)、14(3)与引线58断开连接并且将每个第一多芯光纤连接器30(1)、30(2)、30(3)连接到接插板20外壳中的多芯光纤适配器组件34(步骤2016)。将各个第二多芯光纤连接器32(1)、32(2)、32(3)连接到位于分配层24、26、28处的FDT29中的各自多芯光纤适配器组件34(步骤2018)。可以将直立电缆14的散堆存储在分配层24、26、28处的FDT29中以及/或者存储在牵出线轴18(1)、18(2)、18(3)中(步骤2020)。牵出线轴18(1)、18(2)、18(3)可以以可移除方式安装在FDT29中。散堆还可以存储在接插板外壳20中。
图11为与MDU10中的光纤网络一起使用的示例性LCP40的前部透视示意图.LCP40包括外壳72,其中门74以铰链方式附接到外壳72。门74关闭时可以限制和/或抑制接近外壳72的内部76和安装在其中的部件,而打开时则允许接近内部76和安装在其中的部件。可摆动的适配器面板78安装在内部76中。适配器面板78具有第一侧80(在图11中不可见)和第二侧82,这两侧提供了馈电侧与分配侧之间的光纤83连接。内部76的顶部和底部处的枢转点96使适配器面板可以摆动从而根据适配器面板78的定位来使用第一侧80或第二侧82。此外,适配器面板可以锁定在一个或多个位置。适配器面板78将内部76分裂为第一部分84和第二部分86。LCP40为柔性的,这使得第一部分84或第二部分86中的一者或两者可以经配置以支持馈电侧光纤83的管理和/或连接,以及/或者支持分配侧光纤83的管理和/或连接。
适配器面板78具有连接区域88,用于支撑光纤适配器和连接件以及传递适配器和连接件。在图11中,所示馈电电缆42在底部进入LCP40到达第一部分84中并且连接到熔接盒92。馈电电缆42中的连续部分42(1)从第二侧86的底部延伸出去以进一步从服务供应商向MDU10的其他区域以及/或者其他MDU所在地和/或设施提供光连接。分配电缆36从第一部分84的顶部延伸出去。分配电缆36光学连接到一个或多个直立电缆14,这可以通过接插板壳体20中的多芯光纤适配器组件34来实现。一个或多个分裂器94也可以安装在LCP40中以将馈电电缆42所传送的光信号分裂为用于分配的多个光信号。光纤路由引导器98和光纤管理引导器100也可以安装在第一部分84和/或第二部分86中。
图11A、图11B和图11C为LCP40的前部透视分解示意图,其示出了可以用于LCP40中的内部面板102(1)、102(2)、102(3)。内部面板102(1)、102(2)、102(3)可以互换并且使LCP40的外壳72能够在工厂或在现场容易重新配置。这使得外壳72可以进行配置和重新配置以支持多种应用和不同的订户状况。这样,内部面板102(1)、102(2)、102(3)可以支持但不限于以下功能:光纤熔接、多个分裂器形状因子、电缆引入以及LCP40的其他各种修改或布置方案。此外,内部面板102(1)、102(2)、102(3)可以使用任何类型的紧固件104而安装在内部76的第一部分84或第二部分86上,所述紧固件例如但不限于允许可移除附接的螺钉、栓锁等。
