具体实施方式
现在将详细参照具体实施方案,所述实施方案的实施例示出在附图中,在一些附图中,并非示出了所有特征。实际上,本文公开的实施方案可以以许多不同形式实施,不应理解为限制于本文列出的实施方案;而是,提供这些实施方案使得本公开文本满足适用的法律要求。无论何时,只要可能,将使用相同的参考数字表示相同的部件或部分。
在详细说明中公开的实施方案包括高密度光纤模块和光纤模块壳以及相关的设备。在某些实施方案中,可分别根据与光纤模块和光纤模块壳的主体的前侧的宽度和/或高度的设定关系设定所述光纤模块和/或光纤模块壳的前开口的宽度和/或高度,以支承光纤部件或连接。如此,可将光纤部件安装在光纤模块的前侧的指定比例或区域中,从而为指定光纤部件类型提供高密度的光纤连接。在另一个实施方案中,可设置光纤模块和/或光纤模块壳的前开口,从而为光纤模块和/或光纤模块壳的前开口的指定宽度和/或高度支承光纤部件或连接的设计连接密度。在详细说明中公开的实施方案还包括高连接密度和带宽光纤装置以及相关设备。在某些实施方案中,设有光纤装置,所述光纤装置包括一个盘架,该盘架限定一个或多个U空间(Uspace)光纤设备单元,其中所述一个或多个U空间光纤设备单元中的至少一个被配置为在一个1-U空间中、以及对于指定的光纤部件类型支承指定的光纤连接密度或带宽。
在详细说明中公开的实施方案还包括包含有光纤设备架的光纤装置。所述光纤设备架限定至少一个1-U空间光纤设备单元。所述1-U空间光纤设备单元被配置为保持住光纤设备,包含一个或多个光导纤维的一个或多个光纤电缆通过至少一个LC双工或单工的、12纤维MPO或24纤维MPO光纤连接器连接至所述光纤设备。从所述至少一个1-U空间光纤设备单元中延伸出一个电缆路由区域,其中光导纤维在所述电缆路由区域的至少一部分中被路由,以及其中所述光导纤维在电缆路由区域中保持如TIA/EIA-568标准中规定的10-12误码率以及0.75dB的衰减极限。所述电缆路由区域被配置为使得所述一个或多个光纤电缆在电缆路由区域中仅弯曲偏离所述光纤连接器一次,并总体水平地路由通过所述电缆路由区域。
此外,如在此所使用的,术语“光纤电缆”和/或“光导纤维”意在包括所有类型的单模或多模光波导,包括一个或多个裸光导纤维、松套管光导纤维、紧密-缓冲光导纤维、带状光导纤维、抗弯光导纤维,或任何其他用于传输光信号的有利介质。
在这方面,图1示出了从正视立体图观察的示例的1-U尺寸的光纤设备10。如下面将更详细说明的,所述光纤设备10支承高密度光纤模块,所述高密度光纤模块在一个1-U空间中支承高的光纤连接密度以及带宽。所述光纤设备10可被设置在数据分布中心或中央局,以支承电缆-电缆光纤连接以及管理多个光纤电缆连接。如下面更详细说明的,光纤设备10具有一个或多个光纤设备托盘,所述光纤设备托盘中的每一个支承一个或多个光纤模块。然而,所述光纤设备10还可适于支承一个或多个光纤接线板、或支承那些支承光纤部件和连接性的其他光纤设备。
所述光纤设备10包括一个光纤设备盘架12(“盘架12”)。所述盘架12被示为安装在光纤设备架14中。所述光纤设备架14包括两个竖直轨道16A、16B,所述轨道竖向延伸并且包括一系列孔18,以便于将盘架12附接在光纤设备架14内。所述盘架12被光纤设备架14附接和支承,光纤设备架14具有如下的搁架形式,所述搁架在竖直轨道16A、16B内相互堆叠。如示出的,盘架12附接至竖直轨道16A、16B。所述光纤设备架14可支承1-RU尺寸的搁架,“U”等于标准的1.75英寸高以及十九(19)英寸宽。在一些应用中,“U”的宽度可以是二十三(23)英寸。此外,术语光纤设备架14应理解为还包括柜子的结构。在本实施方案中,盘架12的尺寸是1-U;然而,盘架12还可被设置为大于1-U的尺寸。
如稍后在下文更详细讨论的,光纤设备10包括多个可延伸的光纤设备托盘20,所述光纤设备托盘中的每一个都带有一个或多个光纤模块22。所述盘架12和光纤设备托盘20支承光纤模块22,所述光纤模块在一个指定空间(包括在1-U空间中)中支承高密度光纤模块和光纤连接密度以及带宽连接。图1示出布置在支承光纤连接的光纤模块22中的示例的光纤部件23。例如,光纤部件23可以是光纤适配器或光纤连接器。如稍后在下文更详细讨论的,本实施方案中的光纤模块22可被设置为使得作为一个实施例,光纤部件23可布置通过光纤模块22的前侧或正面的宽度的至少百分之八十五(85%)。这样的光纤模块22配置可提供大约90毫米(mm)或更小的前开口,其中光纤部件可被布置通过该前开口,且可被布置为具有如下光纤连接密度,即,对于单工或双工光纤部件23,光纤模块22的前开口的宽度的每7.0mm具有至少一个光纤连接。在该实施例中,每个光纤模块22中可安装六个(6)双工、或十二个(12)单工光纤部件。在该实施方案中,所述光纤设备托盘20在大约1-U空间的宽度内支承多达四个(4)光纤模块22,在1-U空间的高度内存在三个(3)光纤设备托盘20,从而在1-U空间中获得总共十二个(12)光纤模块22。因此,例如,如果在安装在如图1示出的盘架12的光纤设备托盘20中的十二个(12)光纤模块22的每一个中布置有六个(6)双工光纤部件,则盘架12在1-U空间中将支承总共一百四十四个(144)光纤连接,或者七十二个(72)双工信道(即,发送和接收信道)。如果安装在盘架12的光纤设备托盘20中的十二个(12)光纤模块22的每一个中布置有五个(5)双工光纤适配器,则盘架12在1-U空间中将支承总共一百二十个(120)光纤连接,或者六十个(60)双工信道。在一个1-U空间中,所述盘架12还支承至少九十八个(98)光纤部件,其中所述光纤部件中的至少一个是单工或双工光纤部件。
如果在所述光纤模块22中安装了多纤维的光纤部件,诸如像MPO部件,则在其他的使用类似光纤部件的托架12上有可能实现更高的光纤连接密度和带宽。例如,如果在每个光纤模块22中布置了多达四个(4)十二(12)纤维MPO光纤部件,且在1-U空间中的盘架12中布置了十二个(12)光纤模块22,则盘架12将在1-U空间中支承高达五百七十六个(576)光纤连接。如果在每个光纤模块22中布置了高达四个(4)二十四(24)纤维MPO光纤部件,且在盘架12中布置了十二个(12)光纤模块22,则在1-U空间中存在高达一千一百五十二个(1152)光纤连接。
图2是图1的盘架12的后视立体特写图,其中光纤模块22装载有光纤部件23,并安装在光纤设备托盘20中,所述光纤设备托盘20安装在盘架12中。在每一个光纤模块22的每一侧上布置有模块轨道28A、28B。所述模块轨道28A、28B被配置为插入在模块轨道导向器32的托盘槽30内,所述模块轨道导向器布置在光纤设备托盘20中,如在图3-5中更详细示出的。应注意,可设置任意数目的模块轨道导向器32。在该实施方案中,所述光纤模块22既可从光纤设备托盘20的前端34开始安装,也可从光纤设备托盘20的后端36开始安装。如果希望从后端36开始将光纤模块22安装在光纤设备托盘20中,则可从光纤设备托盘20的后端36插入光纤模块22的前端33。更具体而言,光纤模块22的前端33被插入模块轨道导向器32的托盘槽30。然后可在托盘槽30内将光纤模块22向前推,直到光纤模块22到达模块轨道导向器32的前端34。所述光纤模块22可移动朝向前端34,直到光纤模块22到达布置在前端34中的挡块或锁定部件,如本申请中稍后将说明的。图6还示出没有安装光纤模块22的光纤设备托盘20,以显示托盘槽30和光纤设备托盘20的其他特征。
通过将光纤模块22推向光纤设备托盘20的前端33,可在所述光纤设备托盘20中将所述光纤模块22锁定就位。如图3和图4的特写图中更详细示出的,一个具有前端挡块38形式的锁定部件被布置在模块轨道导向器32中。如在图5中的安装有光纤模块22的光纤设备托盘20的特写图中示出的,所述前端挡块38防止所述光纤模块22延伸越过前端34。当希望从光纤设备托盘20中移除光纤模块22时,可将一个前端模块接片40向下压以接合所述前端挡块38,所述前端模块接片也布置在模块轨道导向器32中并且联接至所述前端挡块38。结果,所述前端挡块38将向外移动远离光纤模块22,使得光纤模块22不受阻碍地被向前拉动。所述光纤模块22,尤其是其模块轨道28A、28B(图2),可沿着模块轨道导向器32被向前拉动,以将光纤模块22从光纤设备托盘20中移除。
还可从光纤设备托盘20的后端36移除所述光纤模块22。为了将所述光纤模块22从光纤设备托盘20的后端36移除,通过将一个杆46(参见图2和3;还参见图10A和10B)朝内推向光纤模块22使闩锁44打开,将所述闩锁44从模块轨道导向器32中脱离。为了便于将所述杆46向内推向所述光纤模块22,在所述杆46附近设置一个指状钩48,使得通过拇指和食指可轻易将所述杆46挤进指状钩48。
继续参照图3-6,光纤设备托盘20还可包括延伸构件50。路由导向器52可便利地布置在延伸构件50上,从而为连接至布置在光纤模块22中的光纤部件23的光导纤维或光纤电缆提供路由(图3)。光纤设备托盘20的端部上的路由导向器52’可相对于模块轨道导向器32成角度,从而以与光纤设备托盘20的侧面成一个角度地路由所述光导纤维或光纤电缆。拉片(pul1 tab)54还可连接至所述延伸构件50,以提供一种允许轻易地从盘架12拉出光纤设备托盘20以及将光纤设备托盘20推入盘架12的方式。
如图3和6中所示,光纤设备托盘20还包含托盘轨道56。如图7中所示,所述托盘轨道56被配置为容纳在托盘导向器58中,所述托盘导向器布置在盘架12中以保持并允许所述光纤设备托盘20移入和移出所述盘架12。关于托盘轨道56和它们联接到盘架12中的托盘导向器58的更多细节在下文关于图8和图9A-9B进行讨论。光纤设备托盘20可通过它们的在托盘导向器58内移动的托盘轨道56移入和移出盘架12。这样,光纤设备托盘20能够关于盘架12中的托盘导向器58独立地可移动。图7示出在布置在盘架12的托盘导向器58内的三个光纤设备托盘20中从盘架12拉出一个光纤设备托盘20的正视立体图。托盘导向器58既可布置在光纤设备托盘20的左侧端60,也可布置在光纤设备托盘20的右侧端62。所述托盘导向器58相对安装,并且在盘架12内朝向彼此,以对于容纳在其中的光纤设备托盘20的托盘轨道56提供互补的托盘导向器58。如果希望获取某一个具体的光纤设备托盘20和/或一个光纤设备托盘20中的一个具体的光纤模块22,可向前拉动想要的光纤设备托盘20的拉片54,以使光纤设备托盘20从盘架12中向前延伸出,如图7中所示。如前所述,光纤模块22能够从光纤设备托盘20中移出。当获取完毕时,光纤设备托盘20能够被推回到盘架12中,其中托盘轨道56在布置于盘架12中的托盘导向器58内移动。
图8是布置在图1的盘架12中的一个示例托盘导向器58的左视立体图。如上所述,所述托盘导向器58被配置为在盘架12中接收光纤设备托盘20,所述光纤设备托盘20支承一个或多个光纤模块22。如图7中所示,托盘导向器58允许光纤设备托盘20被拉出盘架12。本实施方案中的托盘导向器58由导向面板64组成。所述导向面板64可由任意想要的材料构成,包括但不限于聚合物或金属。如图8中所示,所述导向面板64包括一系列孔66,以便于导向面板64附接到盘架12。导向构件68布置在导向面板64中,并被配置为接收光纤设备托盘20的托盘轨道56。在图8的实施方案中,三个(3)导向构件68布置在导向面板64中,以能够在1-U空间中容纳三个(3)光纤设备托盘20中的多达三个(3)托盘轨道56。然而,可在托盘导向器58中设置想要的任意数目的导向构件68,以覆盖小于或大于1-RU空间的尺寸。在本实施方案中,每个导向构件68都包括导向槽70,所述导向槽70配置为接收托盘轨道56并允许托盘轨道56沿着导向槽70移动,以实现光纤设备托盘20关于盘架12的平移。
在托盘导向器58的每个导向构件68中都布置有板簧72,每个板簧都被配置为在光纤设备托盘20于导向构件68中移动的过程中,为托盘轨道56提供停止位置。每个板簧72都包括止动器(detent)74,所述止动器被配置为容纳布置在托盘轨道56中的突出物76(图9A-9D),以提供停止位置或停靠位置。托盘轨道56包括安装台75,所述安装台75用于将托盘轨道56附接至光纤设备托盘20。可期望在托盘导向器56中提供停止位置,以允许光纤设备托盘20在移入和移出盘架12时具有停止位置。在任意指定时间,托盘轨道56中的两个(2)突出物76都布置在托盘导向器58中的两个(2)止动器74中。当光纤设备托盘20在第一停止位置完全缩回到盘架12中时,托盘轨道56的两个(2)突出物76布置在导向槽70的后端77附近的一个止动器74中、以及布置在导向槽70的后端77和前端78之间的中间止动器74中。当光纤设备托盘20从盘架12中拉出时,托盘轨道56的两个(2)突出物76布置在导向槽70的前端78附近的一个止动器74中、以及布置在导向槽70的后端77和前端78之间的中间止动器74中。
如图8中所示,在导向槽70内拉动托盘轨道56时,图9A和9B中示出的、以及布置在托盘轨道56中的突出物80偏移以越过在布置于板簧72之间的转接构件82。如图9A和9B中所示,突出物80设置在布置于托盘轨道56中的一个板簧81中。转接构件82具有倾斜面84,所述倾斜面允许在光纤设备托盘20相对于导向槽70平移时,突出物80越过转接构件82。由于突出物80包括转接构件82,因此传递到突出物80上的力导致板簧81向内弯曲,以允许突出物80越过转接构件82。为了防止托盘轨道56、并从而防止光纤设备托盘20延伸超出导向槽70的前端78和后端77,在导向槽70的前端78和后端77布置有停止构件86。停止构件86不具有倾斜面,从而托盘轨道56中的突出物80邻靠所述停止构件86,从而防止延伸超出停止构件86以及延伸到导向槽70的前端78以外。
在上面公开的1-U盘架12和光纤设备托盘20以及能够安装于其中的光纤模块22的实施方案的背景下,现在将描述光纤模块22的形状因素(form factor)。光纤模块22的形状因素允许高密度的光纤部件23被布置在光纤模块22的前端的一比例区域内,从而为指定的光纤部件23类型支持特定的光纤连接密度和带宽。当这样的光纤模块22形状因素与(如上面的示例的盘架12实施例所描述的)在1-U空间中支持高达12个(12)光纤模块22的能力相结合时,支持并且可实现更高的光纤连接密度和带宽。
在这方面,图10A和10B是示例的光纤模块22的右视立体图和左视立体图。如上所述,光纤模块22能够安装在光纤设备托盘20中,以在盘架12中提供光纤连接。光纤模块22由一个主体90组成,该主体接收一个盖子92。在主体90和盖子92里面布置了一个内腔94(图11),该内腔被配置用于接收或保持光导纤维或光纤电缆线束,如下面更详细描述的。所述主体90被布置在所述主体90的前侧96和后侧98之间。光纤部件23能够被布置通过主体90的前侧96,并且被配置用于接收连接至光纤电缆(未示出)的光纤连接器。在本实施例中,光纤部件23是双工LC光纤适配器,该双工LC光纤适配器被配置用于接收和支持与双工LC光纤连接器的连接。然而,在光纤模块22中可以设置想要的任意光纤连接类型。光纤部件23连接至布置通过主体90的后侧98的光纤部件100。这样,与光纤部件23的连接形成了与光纤部件100的连接。在本实施例中,光纤部件100是多纤维MPO光纤适配器,其被配备以形成与多根光导纤维(例如,十二(12)或二十四(24)根光导纤维)的连接。光纤模块22还可管理光纤部件23、100之间的极性。
模块轨道28A、28B布置在光纤模块22的每一侧102A、102B。如前所述,模块轨道28A、28B被配置用于插入光纤设备托盘20中的模块轨道导向器32内,如图3中所示。这样,当希望将光纤模块22安装在光纤设备托盘20中时,如前所述,光纤模块22的前侧96可从光纤设备托盘20的前端33插入,或者从光纤设备托盘20的后端36插入。
图11示出了光纤模块22的分解图,其中去除了光纤模块22的盖子92,以示出光纤模块22的内腔94和其他内部部件。图12示出已装配好的光纤模块22,但在主体90上没有安装盖子92。所述盖子92包括布置在侧面108、110中的凹口106,所述凹口被配置用于当盖子92附接至主体90以将盖子92固定至主体90时,与布置在光纤模块22的主体90的侧面102A、102B上的突出物112互锁。所述盖子92还包括分别布置在盖子92的前侧118和后侧面120上的凹口114、116。所述凹口114、116被配置用于当盖子92附接至主体90以也将盖子92固定至主体90时,分别与布置在主体90的前端96和后端98中的突出物122、124互锁。图12未示出突出物122、124。
继续参照图11,光纤部件23被布置为通过一个在主体90的前侧96中沿纵向轴线L1布置的一个前开口126。在本实施方案中,光纤部件23是双工LC适配器128,该适配器支持单工或双工纤维连接和连接器。本实施方案中的双工LC适配器128包括突出物130,所述突出物被配置为与布置在主体90上的孔口135接合,以将本实施方案中的双工LC适配器128固定在主体90中。电缆束134布置在内腔94中,同时光纤连接器136、138布置在连接至双工LC适配器128的光导纤维139的每一端部上,光纤部件100布置在主体90的后侧98。本实施方案中的光纤部件100是本实施方案中的十二(12)纤维MPO光纤适配器140。如图12中所示,在主体90的内腔94中布置了两个竖直构件142A、142B,以保持电缆束134的光导纤维139的环形。在本实施方案中,竖直构件142A、142B以及二者之间的距离被设计为在光导纤维139中提供一个不超过四十(40)mm的弯曲半径R,优选为二十五(25)mm或更小。
图13示出在前侧96没有安装光纤部件23的光纤模块22的正视图,以进一步示出光纤模块22的形状因素。如前所述,前开口126被布置穿过主体90的前侧96以接收光纤部件23。前开口126的宽度W1越大,可布置在光纤模块22中的光纤部件23的数目就越多。较多数目的光纤部件23对应于较多的光纤连接,这支持了较高的光纤连接和带宽。然而,前端开口126的宽度W1越大,需要在盘架12中设置的用于光纤模块22的面积就越大。因此,在该实施方案中,前开口126的宽度W1被设计为是光纤模块22的主体90的前侧96的宽度W2的至少百分之八十五(85%)。宽度W1与宽度W2的百分比越大,在不增加宽度W2的情况下,设置在前开口126中用于接收光纤部件23的面积就越大。在本实施方案中,宽度W3——光纤模块22的总体宽度——可以是86.6mm或3.5英寸。在该实施方案中,光纤模块22的总体深度D1是113.9mm或4.5英寸(图12)。如上所述,光纤模块22被设计使得,在盘架12的光纤设备托盘20中的1-U宽度空间中可布置四个(4)光纤模块22。在本实施方案中,盘架12的宽度被设计为容纳1-U空间宽度。
使用布置在盘架12的1-U高度中的三个(3)光纤设备托盘20,可在指定的1-U空间中支承总共十二个(12)光纤模块22。如图1中的盘架12中所示,在盘架12的1-U空间中,每个光纤模块22支承高达十二个(12)光纤连接等于盘架12支承高达一百四十四个(144)光纤连接、或七十二个(72)双工信道(即,十二个(12)光纤连接乘以1-U空间中的十二个(12)光纤模块22)。从而,通过布置在光纤模块22中的十二个(12)单工或六个(6)双工光纤适配器,盘架12能够在1-U空间中支承高达一百四十四个(144)光纤连接。在盘架12的1-U空间中,每个光纤模块22支承高达十个(10)光纤连接等于盘架12支承一百二十个(120)光纤连接、或六十个(60)双工信道(即,十个(10)光纤连接乘以1-U空间中的十二个(12)光纤模块22)。因此,通过布置在光纤模块22中的十个(10)单工或五个(5)双工光纤适配器,盘架12还能够在1-U空间中支承高达一百二十个(120)光纤连接。
此处公开的盘架12和光纤模块22的这个实施方案能够支持在1-U空间中的光纤连接密度,其中1-U空间中的十二个(12)光纤模块22中的光纤部件23所占据的面积代表了1-U空间中的总光纤设备架14(见图1)面积的至少百分之五十(50%)。在盘架12的1-U空间中设置了十二个(12)光纤模块22的情况中,1-U空间由占据光纤模块22的前侧96的面积的至少百分之七十五(75%)的光纤部件23组成。
两个(2)双工光导纤维提供一个(1)发送/接收对能够在半双工模式中允许每秒十(10)吉比特的数据速率,或者在全双工模式中允许每秒二十(20)吉比特的数据速率。因此,对于上述实施方案,如果使用十(10)吉比特收发机的话,使用至少一个双工或单工光纤部件在1-U空间提供至少七十二个(72)双工发送和接收对,能够在1-U空间中在半双工模式支承每秒至少七百二十(720)吉比特的数据速率,或者能够在1-U空间中在全双工模式支承每秒至少一千四百四十(1440)吉比特的数据速率。如果使用一百(100)吉比特收发机,这样的配置还能够分别在1-U空间在半双工模式支承每秒至少六百(600)吉比特,以及在1-U空间在全双工模式支承每秒至少一千二百(1200)吉比特。如果使用四十(40)吉比特收发机,这样的配置还能够分别在1-U空间在半双工模式支承每秒至少四百八十(480)吉比特,以及在1-U空间在全双工模式支承每秒至少九百六(960)吉比特。在使用十(10)吉比特收发机时,1-U空间中至少六十个(60)双工发送和接收对能够允许在1-U空间在半双工模式中的每秒至少六百(600)吉比特的数据速率,或者允许在1-U空间在全双工模式每秒至少一千二百(1200)吉比特的数据速率。在使用十(10)吉比特收发机时,1-U空间中至少四十九个(49)双工发送和接收对能够允许在1-U空间在半双工模式中的每秒至少四百八十一(481)吉比特的数据速率,或者允许在1-U空间在全双工模式每秒至少九百六十二(962)吉比特的数据速率。
前开口126的宽度W1可被设计为大于光纤模块22的主体90的前侧96的宽度W2的百分之八十五(85%)。例如,宽度W1可被设计为在宽度W2的百分之九十(90%)和百分之九十九(99%)之间。作为一个实施例,宽度W1可小于九十(90)mm。作为另一个实施例,宽度W1可小于八十五(85)mm或小于八十(80)mm。例如,宽度W1可是八十三(83)mm,宽度W2可是八十五(85)mm,宽度W1与宽度W2的比率为97.6%。在本实施例中,前开口126可在宽度W1中支持十二个(12)光纤连接,以支持前开口126的宽度W1的每7.0mm至少一个光纤连接的光纤连接密度。此外,光纤模块22的前开口126可在宽度W1中支持十二个(12)光纤连接,以支持前开口126的宽度W1的每6.9mm至少一个光纤连接的光纤连接密度。
进一步如图13中所示,前开口126的高度H1可被设计为是光纤模块22的主体90的前侧96的高度H2的至少百分之九十(90%)。这样,前开口126具有足够的高度来容纳光纤部件23,使得在1-U空间高度中能够布置三个(3)光纤模块22。作为一个实施例,高度H1可以是十二(12)mm或更小,或是十(10)mm或更小。作为一个实施例,高度H1可是十(10)mm,高度H2可是十一(11)mm(或7/16英寸),高度H1与高度H2的比率为90.9%。
具有其他光纤连接密度的替代光纤模块是可行的。图14是能够安装在图1的光纤设备托盘20中的一个替代的光纤模块22’的正视立体图。光纤模块22’的形状因素与图1-13中所示的光纤模块22的形状因素相同。但是,在图14的光纤模块22’中,两个(2)MPO光纤适配器150布置通过光纤模块22’的前开口126。所述MPO光纤适配器150连接至布置在光纤模块22’的主体90的后侧98中的两个MPO光纤适配器152。因此,如果MPO光纤适配器150每个都支承十二根(12)纤维,则光纤模块22’能够支持高达二十四个(24)光纤连接。因此,在该实施例中,如果在盘架12的光纤设备托盘20中设置了高达十二个(12)光纤模块22’,则盘架12在1-U空间中能够支承高达二百八十八个(288)光纤连接。此外,在这个实施例中,光纤模块22’的前开口126可在宽度W1(图13)中支承二十四个(24)光纤连接,以支承前开口126的宽度W1的每3.4-3.5mm至少一个光纤连接的光纤连接密度。应理解,关于模块的讨论还可应用于面板。为了本公开文本的内容,面板可在一侧具有一个或多个适配器,在相对侧不具有适配器。
因此,对于上述实施方案,如果使用十(10)吉比特收发机的话,使用至少一个十二(12)纤维MPO光纤部件在1-U空间提供至少二百八十八个(288)双工发送和接收对,则能够在1-U空间在半双工模式支承每秒至少二千八百八十(2880)吉比特的数据速率,或者在1-U空间在全双工模式支承每秒至少五千七百六十(5760)吉比特的数据速率。如果使用一百(100)吉比特收发机,这样的配置还能够分别在1-U空间在半双工模式支承每秒至少四千八百(4800)吉比特,以及在1-U空间在全双工模式支承每秒至少九千六百(9600)吉比特。如果使用四十(40)吉比特收发机,这样的配置还能够分别在1-U空间在半双工模式支承每秒至少一千九百二十(1920)吉比特,以及在1-U空间在全双工模式支承每秒至少三千八百四十(3840)吉比特。在使用十(10)吉比特收发机、使用至少一个十二(12)纤维MPO光纤部件时,这样的配置还支承在1-U空间在全双工模式中实现每秒至少四千三百二十二(4322)吉比特的数据速率,或者在使用十(10)吉比特收发机、使用至少一个二十四(24)纤维MPO光纤部件时,在1-U空间在全双工模式支承每秒至少两千一百六十一(2161)吉比特的数据速率。
如果光纤模块22’中的MPO光纤适配器150支承二十四根(24)纤维,则光纤模块22’能够支承高达四十八个(48)光纤连接。因此,在本实施例中,如果在盘架12的光纤设备托盘20中设置高达十二个(12)光纤模块22’,则如果光纤模块22’布置在光纤设备托盘20中,盘架12在1-U空间中能够支承高达五百七十六个(576)光纤连接。此外,在这个实施例中,光纤模块22’的前开口126可在宽度W1中支承高达四十八(48)个光纤连接,以支承前开口126的宽度W1的每1.7mm至少一个光纤连接的光纤连接密度。
图15是能够安装在图1的光纤设备托盘20中的另一个替代的光纤模块22”的正视立体图。光纤模块22”的形状因素与图1-13中所示的光纤模块22的形状因素相同。但是,在光纤模块22”中,四个(4)MPO光纤适配器154布置通过光纤模块22”的前开口126。所述MPO光纤适配器154连接至布置在光纤模块22”的主体90的后端98中的四个(4)MPO光纤适配器156。因此,如果MPO光纤适配器150支持十二(12)根纤维,则光纤模块22’能够支持高达四十八个(48)光纤连接。因此,在该实施例中,如果在盘架12的光纤设备托盘20中设置了高达十二个(12)光纤模块22”,则盘架12在1-U空间中能够支承高达五百七十六个(756)光纤连接。此外,在这个实施例中,光纤模块22”的前开口126可在宽度W1中支承二十四个(24)光纤连接,以支持前开口126的宽度W1的每1.7mm至少一个光纤连接的光纤连接密度。
如果布置在光纤模块22”中的四个(4)MPO光纤适配器154支承二十四(24)根纤维,则光纤模块22”能够支承高达九十六个(96)光纤连接。因此,在该实施例中,如果在盘架12的光纤设备托盘20中设置了高达十二个(12)光纤模块22”,则盘架12在1-U空间中能够支承高达一千一百五十二个(1152)光纤连接。此外,在这个实施例中,光纤模块22”的前开口126可在宽度W1中支承九十六个(96)光纤连接,以支持前开口126的宽度W1的每0.85mm至少一个光纤连接的光纤连接密度。
此外,对于上述实施方案,如果使用十(10)吉比特收发机,则使用至少一个二十四(24)纤维MPO光纤部件在1-U空间提供至少五百七十六个(576)双工发送和接收对,能够在1-U空间在半双工模式支承每秒至少五千七百六十(5760)吉比特的数据速率,或者在1-U空间在全双工模式支承每秒至少一万一千五百二十(11520)吉比特的数据速率。如果使用一百(100)吉比特收发机,这样的配置还能够分别在1-U空间在半双工模式支承每秒至少四千八百(4800)吉比特,以及在1-RU空间在全双工模式支承每秒至少九千六百(9600)吉比特。如果使用四十(40)吉比特收发机,这样的配置还能够分别在1-U空间在半双工模式支承每秒至少三千八百四十(3840)吉比特,以及在1-U空间在全双工模式支承每秒至少七千六百八十(7680)吉比特。在使用十(10)吉比特收发机、使用至少一个二十四(24)纤维MPO光纤部件时,这样的配置还在1-U空间在全双工模式中支承每秒至少八千六百四十二(8642)吉比特的数据速率,或者在使用十(10)吉比特收发机、使用至少一个二十四(24)纤维MPO光纤部件时,在1-U空间在全双工模式支承每秒至少四千三百二十一(4321)吉比特的数据速率。
图16示出可设置在光纤设备托盘20中以支持光纤连接以及连接密度和带宽的一个替代光纤模块160。图17是图16的光纤模块160的正视右立体图。在这个实施方案中,光纤模块160被设计为横置在两组模块轨道导向器32上。槽162布置通过光纤模块160的中心轴线164,以接收在光纤设备托盘20中的模块轨道导向器32。模块轨道165A、165B——类似于图1-13中的光纤模块22的模块轨道28A、28B——被布置在光纤模块160的槽162内侧,并被配置为与光纤设备托盘20中的托盘槽30相接合。模块轨道166A、166B——类似于图1-13中的光纤模块22的模块轨道28A、28B——被布置在光纤模块160的每一侧168、170上,并被配置为与光纤设备托盘20中的托盘槽30相接合。布置在光纤模块160的侧面168、170上的所述模块轨道166A、166B被配置为与模块轨道导向器32中的托盘槽30相接合,且布置在多个模块轨道导向器32之间并与模块轨道导向器32相接合。
在光纤模块160的前侧172可布置高达二十四个(24)光纤部件23。在这个实施方案中,光纤部件23由高达十二个(12)双工LC光纤适配器组成,所述双工LC光纤适配器连接至布置在光纤模块160后端176中的一个二十四(24)纤维MPO光纤连接器174。从而,使用布置在盘架12的高度中的三个(3)光纤设备托盘20,可以在指定的1-U空间中支承总共六个(6)光纤模块160。在盘架12的1-U空间中,每个光纤模块160支承高达二十四个(24)光纤连接等于盘架12支承高达一百四十四个(144)光纤连接、或者七十二个(72)双工信道(即,二十四个(24)光纤连接乘以1-U空间中的六个(6)光纤模块160)。从而,通过布置在光纤模块160中的二十四个(24)单工或十二个(12)双工光纤适配器,盘架12能够在1-RU空间中支承高达一百四十四个(144)光纤连接。在盘架12的1-U空间中,每个光纤模块160支承高达二十个(20)光纤连接等于盘架12支承一百二十个(120)光纤连接、或六十个(60)双工信道(即,二十个(20)光纤连接乘以1-U空间中的六个(6)光纤模块160)。从而,通过布置在光纤模块160中的二十个(20)单工或十个(10)双工光纤适配器,盘架12还能够在1-U空间中支承高达一百二十个(120)光纤连接。
图18示出图16-17的光纤模块160的正视图,其中在前侧172没有安装光纤部件23,以进一步示出本实施方案中的光纤模块160的形状因素。设置在槽162的每一侧的前开口178A、178B被布置通过光纤模块160的主体180的前侧172,以接收光纤部件23。宽度W1和W2以及高度H1和H2与图13中所示的光纤模块22中的宽度和高度相同。因此,在本实施方案中,前开口178A、178B的宽度W1被设计为至少是光纤模块160的主体180的前侧172的宽度W2的至少百分之八十五(85%)。宽度W1和宽度W2的百分比越大,在不增加宽度W2的情况下,在前开口178A、178B中设置用于接收光纤部件23的面积就越大。
前开口178A、178B的宽度W1中的每一个都可被设计为大于光纤模块160的主体180的前侧172的宽度W2的百分之八十五(85%)。例如,宽度W1可被设计为在宽度W2的百分之九十(90%)和百分之九十九(99%)之间。作为一个实施例,宽度W1可小于九十(90)mm。作为另一个实施例,宽度W1可小于八十五(85)mm或小于八十(80)mm。例如,宽度W1可以是八十三(83)mm,宽度W2可以是八十五(85)mm,宽度W1与宽度W2的比率为97.6%。在本实施例中,前开口178A、178B可在宽度W1中支承十二个(12)光纤连接,以支承前开口178A、178B的宽度W1的每7.0mm至少一个光纤连接的光纤连接密度。此外,前开口178A、178B中的每一个都可在宽度W1中支承十二个(12)光纤连接,以支承前开口178A、178B的宽度W1的每6.9mm至少一个光纤连接的光纤连接密度。
进一步如图18中所示,前开口178A、178B的高度H1可被设计为是光纤模块160的主体180的前侧172的高度H2的至少百分之九十(90%)。这样,前开口178A、178B具有足够的高度来容纳光纤部件23,同时在1-RU空间的高度中能够布置三个(3)光纤模块160。作为一个实施例,高度H1可以是十二(12)mm或更小,或是十(10)mm或更小。作为一个实施例,高度H1可以是十(10)mm,高度H2可以是十一(11)mm,高度H1与高度H2的比率为90.9%。
图19示出可设置在光纤设备托盘20中以支持光纤连接以及连接密度和带宽的另一个替代光纤模块190。图20是图19的光纤模块190的正视右立体图。在这个实施方案中,光纤模块190被设计为横置在在两组模块轨道导向器32上。纵向贮槽(longitudinal receiver)192布置通过中心轴线194,并被配置为通过贮槽192中的开口193接收光纤设备托盘20中的模块轨道导向器32。模块轨道195A、195B——类似于图1-13中的光纤模块22的模块轨道28A、28B——被布置在光纤模块190的每一侧198、200上,并被配置为与光纤设备托盘20中的托盘槽30相接合。
在光纤模块190的前侧202中可布置高达二十四个(24)光纤部件23。在这个实施方案中,光纤部件23由高达十二个(12)双工LC光纤适配器组成,所述双工LC光纤适配器连接至布置在光纤模块190后端206中的一个二十四(24)纤维MPO光纤连接器204。从而,使用布置在盘架12的高度中的三个(3)光纤设备托盘20,可以在指定的1-U空间中支承总共六个(6)光纤模块190。在盘架12的1-U空间中,每个光纤模块190支承高达二十四个(24)光纤连接等于盘架12支承高达一百四十四个(144)光纤连接、或者七十二个(72)双工信道(即,二十四个(24)光纤连接乘以1-U空间中的六个(6)光纤模块190)。从而,通过布置在光纤模块190中的二十四个(24)单工或十二个(12)双工光纤适配器,盘架12能够在1-U空间中支承高达一百四十四(144)光纤连接。在盘架12的1-U空间中,每个光纤模块190支承高达二十四个(20)光纤连接等于盘架12支承一百二十个(120)光纤连接、或六十个(60)双工信道(即,二十个(20)光纤连接乘以1-U空间中的六个(6)光纤模块190)。从而,通过布置在光纤模块190中的二十个(20)单工或十个(10)双工光纤适配器,盘架12还能够在1-U空间中支承高达一百二十个(120)光纤连接。
图21示出图19-20的光纤模块190的正视图,其中在前侧202没有安装光纤部件23,以进一步示出光纤模块190的形状因素。前开口208A、208B被设置在贮槽192的每一侧上并且通过光纤模块190的主体210的前侧202,以接收光纤部件23。宽度W1和W2以及高度H1和H2与图13中所示的光纤模块22中的宽度和高度相同。因此,在本实施方案中,前开口208A、208B的宽度W1被设计为是光纤模块190的主体210的前侧202的宽度W2的至少百分之八十五(85%)。宽度W1和宽度W2的百分比越大,在不增加宽度W2的情况下,在前开口208A、208B中设置用于接收光纤部件23的面积就越大。
前开口208A、208B的宽度W1中的每一个都可被设计为大于光纤模块190的主体210的前侧202的宽度W2的百分之八十五(85%)。例如,宽度W1可被设计为在宽度W2的百分之九十(90%)和百分之九十九(99%)之间。作为一个实施例,宽度W1可小于九十(90)mm。作为另一个实施例,宽度W1可小于八十五(85)mm或小于八十(80)mm。例如,宽度W1可以是八十三(83)mm,宽度W2可以是八十五(85)mm,宽度W1与宽度W2的比率为97.6%。在这个实施例中,前开口208A、208B可在宽度W1中支承十二个(12)光纤连接,以支承前开口208A、208B的宽度W1的每7.0mm至少一个光纤连接的光纤连接密度。此外,前开口208A、208B中的每一个都可在宽度W1中支承十二个(12)光纤连接,以支承前开口208A、208B的宽度W1的每6.9mm至少一个光纤连接的光纤连接密度。
进一步如图21中所示,前开口208A、208B的高度H1可被设计为是光纤模块190的主体210的前侧202的高度H2的至少百分之九十(90%)。这样,前开口208A、208B具有足够的高度来容纳光纤部件23,同时在1-RU空间的高度中能够布置三个(3)光纤模块190。作为一个实施例,高度H1可以是十二(12)mm或更小,或是十(10)mm或更小。作为一个实施例,高度H1可以是十(10)mm,高度H2可以是十一(11)mm,高度H1与高度H2的比率为90.9%。
图22示出可设置在光纤设备托盘20’中以支持在1-U空间中的更高数目的光纤连接以及连接密度和带宽的另一个替代光纤模块220。本实施方案中的光纤设备托盘20’类似于先前讨论的光纤设备托盘20;然而,光纤设备托盘20’仅包括三个(3)模块轨道导向器32而非五个(5)模块轨道导向器32。因此,光纤设备托盘20’在1-RU宽度空间中仅支承两个光纤模块220。从而,所述光纤模块220不需要分别将光纤模块160、190的槽162或贮槽192设置在光纤设备托盘20’中。图23是图22的光纤模块220的正视右立体图。光纤模块220被设计为横置在光纤设备托盘20’中的一组模块轨道导向器32上。如图22中所示,模块轨道225A、225B——类似于图1-13中的光纤模块22的模块轨道28A、28B——被布置在光纤模块220的每一侧228、230上,并被配置为与光纤设备托盘20’中的托盘槽30相接合。
在光纤模块220的前侧232中可布置高达二十四个(24)光纤部件23。在这个实施方案中,光纤部件23由高达十二个(12)双工LC光纤适配器组成,所述双工LC光纤适配器连接至布置在光纤模块220后端236中的一个二十四(24)纤维MPO光纤连接器234。从而,使用布置在盘架12的高度中的三个(3)光纤设备托盘20’,可以在指定的1-U空间中支承总共六个(6)光纤模块220。在盘架12的1-U空间中,每个光纤模块220支承高达二十四个(24)光纤连接等于盘架12支承高达一百四十四个(144)光纤连接、或者七十二个(72)双工信道(即,二十四个(24)光纤连接乘以1-U空间中的六个(6)光纤模块220)。从而,通过布置在光纤模块220中的二十四个(24)单工或十二个(12)双工光纤适配器,盘架12能够在1-RU空间中支承高达一百四十四个(144)光纤连接。在盘架12的1-RU空间中,每个光纤模块220支承高达二十个(20)光纤连接等于盘架12支承一百二十个(120)光纤连接、或六十个(60)双工信道(即,二十个(20)光纤连接乘以1-U空间中的六个(6)光纤模块220)。从而,通过布置在光纤模块220中的二十个(20)单工或十个(10)双工光纤适配器,盘架12还能够在1-U空间中支承高达一百二十个(120)光纤连接。
图24示出图22-23的光纤模块220的正视图,其中在前侧232没有安装光纤部件23,以进一步示出本实施方案中的光纤模块220的形状因素。前开口238通过光纤模块220的主体240的前侧232以接收光纤部件23。前开口238的宽度W4是图13中所示的光纤模块22中的前开口98的宽度W1的两倍。前侧232的宽度W5是大约一百八十八(188)毫米,稍大于图13中所示的光纤模块22中的宽度W3的约两倍。高度H1和高度H2与图13中所示的光纤模块22中的相同。因此,在本实施方案中,前开口238的宽度W4被设计为是光纤模块220的主体240的前侧232的宽度W5的至少百分之八十五(85%)。宽度W4和宽度W5的百分比越大,在不增加宽度W4的情况下,在前开口238中设置用于接收光纤部件23的面积就越大。
前开口238的宽度W4可被设计为大于光纤模块220的主体240的前侧232的宽度W5的百分之八十五(85%)。例如,宽度W4可被设计为在宽度W5的百分之九十(90%)和百分之九十九(99%)之间。作为一个实施例,宽度W4可小于一百八十(180)mm。作为另一个实施例,宽度W4可小于一百七十(170)mm或小于一百六十(160)mm。例如,宽度W4可以是一百六十六(166)mm,宽度W5可以是171mm,宽度W4与宽度W5的比率为166/171=97%。在这个实施例中,前开口238可在宽度W4中支承二十四个(24)光纤连接,以支承前开口238的宽度W4的每7.0mm至少一个光纤连接的光纤连接密度。此外,前开口238可在宽度W4中支承二十四个(24)光纤连接,以支承前开口238的宽度W4的每6.9mm至少一个光纤连接的光纤连接密度。
此外,如图24中所示,前开口238的高度H1可被设计为是光纤模块220的主体240的前侧232的高度H2的至少百分之九十(90%)。这样,前开口238具有足够的高度来容纳光纤部件23,同时在1-RU空间的高度中能够布置三个(3)光纤模块220。作为一个实施例,高度H1可以是十二(12)mm或更小,或是十(10)mm或更小。作为一个实施例,高度H1可以是十(10)mm,高度H2可以是十一(11)mm,高度H1与高度H2的比率为90.9%。
图25示出光纤设备260的另一实施方案,其可包括上文所述的光纤设备托盘并且被示为支承光纤模块。本实施方案中的光纤设备260包括一个4-U尺寸的盘架262,该盘架被配置为支撑住光纤设备托盘,每一个光纤设备托盘支承一个或多个光纤模块。所支承的光纤设备托盘可以是上述的光纤设备托盘20、20’中的任一个,因此这里不再说明。所支承的光纤模块可以是上述的光纤模块22、22’、22”、160、190、220中的任一个,因此这里不再说明。在本实施例中,盘架262被示为支承十二个(12)光纤设备托盘20,每个光纤设备托盘20都能够支承光纤模块22。
上述的托盘导向器58被用在盘架262中,以支承其中的光纤设备托盘20的托盘轨道56,并且允许每个光纤设备托盘20独立地从盘架262中延伸出以及缩回到盘架262中。前门264附接至盘架262,并且被配置为围住盘架262以保护容纳在盘架262中的光纤设备托盘20。盖子266也附接至盘架262,以保护光纤设备托盘20。但是,在盘架262中,可以设置高达十二个(12)光纤设备托盘20。然而,每1-U空间的光纤连接密度和连接带宽仍然相同。光纤连接密度和连接带宽能力已经在上文进行了描述,并同样适用于图25的盘架262,因此这里不再说明。
因此,概括而言,下面的表格总结了一些利用上述的各种实施方案的光纤模块、光纤设备托盘和盘架在1-U和4-U空间中能够提供的光纤连接密度和带宽。例如,用于一个(1)发送/接收对的双工的两根(2)光导纤维能够允许在半双工模式每秒十(10)吉比特的数据速率、在全双工模式每秒二十(20)吉比特的数据速率。作为另一个实施例,用于四个(4)发送/接收对的双工的十二(12)纤维MPO光纤连接器中的八根(8)光导纤维能够允许在半双工模式每秒四十(40)吉比特的数据速率、在全双工模式每秒八十(80)吉比特的数据速率。作为另一个实施例,用于十个(10)发送/接收对的双工的二十四(24)纤维MPO光纤连接器中的二十根光导纤维能够允许在半双工模式实现每秒一百(100)吉比特的数据速率、在全双工模式实现每秒二百(200)吉比特的数据速率。注意到,这个表格是示例性的,此处公开的实施方案不限于下面提供的光纤连接密度和带宽。
除了提供高光纤连接密度的高密度光纤模块以外,还可实现光纤电缆封装密度。图26示出1-U光纤电缆路由区域300,该区域提供高光纤电缆封装密度。尽管在图26中示出的实施方案中,1-U光纤电缆路由区域300被描述为在1-U盘架的前面,所述1-U盘架具有支承带有LC双工适配器的模块的光纤设备托盘,但应理解,关于1-U光纤电缆路由区域300的讨论适用于具有任意U尺寸、带有任意类型适配器的光纤设备,无论所述光纤设备是否包括在模块中,以及模块的尺寸或类型如何。因此,各种U尺寸的光纤设备将具有与1-U光纤电缆路由区域300相等的数目。
所述1-U光纤电缆路由区域300由宽度、高度、深度尺寸限定。在这一实施方案中,图26中标为“X”的宽度尺寸可以是约16.17英寸。图26中标为“Y”的高度尺寸可以是约1.45英寸。图26中标为“Z”的深度尺寸可以是约3.38英寸。因此,所述1-U光纤电缆路由区域300总体居中位于1-U盘架前面,并且可具有如下计算的体积:
16.17英寸×1.45英寸×3.38英寸=79.25英寸3
位于1-U光纤电缆路由区域300内的光纤电缆310可包括连接至光纤设备上的连接器的一个或多个光纤电缆,所述光纤设备位于该1-U空间中,光纤电缆横穿过该1-U空间用于连接至其他光纤设备。然而,所有这些光纤电缆310都可在1-U光纤电缆路由区域300内以基本水平方向路由。这允许连接至位于该1-U空间中的光纤设备上的连接器的光纤电缆310在路由出1-U光纤电缆路由区域300之前弯曲一次。一旦光纤电缆310离开1-U光纤电缆路由区域300,其将向上或向下竖直弯曲,以路由进入和/或离开光纤设备架14。这样,光纤电缆310在路由出光纤设备架14之前弯曲不超过两次。
通过使用抗弯曲纤维,可将更多纤维封装进1-U光纤电缆路由区域300,而不超出误码率(BER)和衰减极限。换言之,可允许更紧凑的弯曲,使得连接至连接器的光纤电缆310在1-U空间占据更小的深度或“Z”尺寸。如TIA/EIA-568标准确定的,用于数据传输的可接受的最大BER是10-12,以及可接受的最大衰减是0.75dB。以下在本公开文本中被称为BER极限和衰减极限。
现在参照图27,1-U光纤电缆路由区域300被示为从1-U空间的前部去除。被示意性描述为从光导纤维电缆310中取出的光导纤维312的一个代表示例被示为在1-U光纤电缆路由区域300中路由。所述光导纤维312被示为横穿过一个竖直切割通过1-U光纤电缆路由区域300的增量式截面314。一个或多个光导纤维可被包括在一个或多个光纤电缆310中,所述光纤电缆310连接至在1-U光纤电缆路由区域300的具体的1-U空间中的光纤设备上的连接上。
在所述连接中的至少一个使用LC单工或双工连接器类型的情况中,至少大约98根光导纤维312可横穿过1-U光纤电缆路由区域300的增量式截面314,而不超过BER极限和/或衰减极限。换言之,每1-U搁板空间可路由至少98根光导纤维312,而不超过BER极限和/或衰减极限。此外,在该情况中,约98根到约144根的光导纤维312可横穿过1-U光纤电缆路由区域300的增量式截面314,而不超过BER极限和/或衰减极限。
在所述连接装置中的至少一个使用12纤维MPO连接器类型的情况中,至少大约434根光导纤维312可横穿过1-U光纤电缆路由区域300的增量式截面314,而不超过BER极限和/或衰减极限。换言之,每1-U搁板空间可路由至少434根光导纤维312,而不超过BER极限和/或衰减极限。此外,在该情况中,约434根到约576根光导纤维312可横穿过1-U光纤电缆路由区域300的增量式截面314,而不超过BER极限和/或衰减极限。
在所述连接装置中的至少一个使用24纤维MPO连接器类型的情况中,至少大约866根光导纤维312可横穿过1-U光纤电缆路由区域300的增量式截面314,而不超过BER极限和/或衰减极限。换言之,每1-U搁板空间可路由至少866根光导纤维312,而不超过BER极限和/或衰减极限。此外,在该情况中,约866根到约1152根光导纤维312可横穿过1-U光纤电缆路由区域300的增量式截面314,而不超过BER极限和/或衰减极限。
此外,不管连接器类型如何,至少约1152根光导纤维312可横穿过1-U光纤电缆路由区域300的增量式截面314,而不超过BER极限和/或衰减极限。换言之,每1-U搁板空间可路由至少1152根光导纤维312,而不超过BER极限和/或衰减极限。
如此处使用的,术语“光纤电缆”和/或“光导纤维”包括所有类型的单模和多模光波导,包括一种或多种可以是无涂层的、有色的、缓冲的、带状的,和/或在电缆中具有其他有组织的或保护性的结构,诸如一种或多种管、强度构件、护套等等。同样地,其他合适类型的光导纤维包括抗弯曲光导纤维、或任何其他有利于传输光信号的介质。抗弯曲光导纤维的一个实施例是可从Corning Incorporated公司商购得到的多模纤维。
应理解,本公开文本不限于所公开的具体实施方案,修改和其他实施方案意在包括在所附权利要求的范围内。尽管此处使用了具体的术语,但它们仅以总的描述性含义使用,而不意在限制。
