EVADA蓄电池E-38-N,12V38AH系列说及简介

带状光缆的部署

我们可以使用下面两种方法来部署MTP预连接带状光缆。种方法使用MTP连接器模块或配线盒。MTP连接器模块是一种小型化的金属或塑料配线盒，内部封装一根一端为MTP连接器另一端为单芯连接器(通常为SC或LC)的分支跳线。

分支跳线两端的连接器在工厂内被预先装配于模块前/后面板的适配器中。现场只需将模块安装进1U或4U的机架式配线架即可。这种模块使得分支的12芯光纤应用方便并受到合理保护。该部署方法特别适用基于成对光纤的串行传输应用。位于模块前面板的单芯连接器可通过单芯双工跳线与机架或机柜的前面板连接构成光纤回路。当我们采用这种MTP预连接带状光缆的部署方法，其检验光学性能的测试系统与普通传统安装方式的测试系统一样简单而直接。简单的链路损耗测试使用一根参考跳线便可完成。下文中我们将对由MTP预连接带状光缆和MTP连接器模块组成的链路损耗测试方法进行概述。

EVADA蓄电池性能的影响因素：

电池是个单个的“原电池”组成，每一个原电池电压大约12伏，原电池串联起来就形成了电压较高的电池，一个12伏的电池由6个原电池组成，24伏的电池由12个原电池组成等等。UPS的电池充电时，每个串联起来的原电池都被充电。原电池性能稍微不同就会导致有些原电池充电电压比别的原电池高，这部分电池就会提前老化。只要串联起来的某一个原电池性能下降，则整个电池的性能就将同样下降。试验证明电池寿命和串联的原电池数量有关，电池电压就越高，老化的就越快。UPS容量一定时，设计时应尽可能让电池电压低，这样UPS电池寿命就越长，对于电池电压一定时，应选择数量少电压高的原电池串联的电池，不要选择数量多电压低的原电池串联的电池。有些厂家UPS的电池电压比较高，这是因为容量一定时，电压越高，电流就越小，就可选用较细的导线和功率较小的半导体，从而降低UPS成本。容量1KVA左右的UPS的电池电压一般为24～96V。

Influencing factors of Evada battery performance:

The battery is a single "primary battery". Each primary batteryhas a voltage of about 12V. When the primary batteries areconnected in series, they form a battery with a higher voltage. A12V battery is composed of 6 primary batteries, a 24V battery iscomposed of 12 primary batteries, etc. When the ups battery ischarged, each primary battery connected in series is charged. Ifthe performance of the primary battery is slightly different, thecharging voltage of some primary batteries will be higher than thatof other primary batteries, and these batteries will age inadvance. As long as the performance of a primary battery connectedin series declines, the performance of the whole battery will alsodecline. The test shows that the battery life is related to thenumber of primary batteries in series. The higher the batteryvoltage is, the faster the aging is. When the ups capacity isfixed, the battery voltage shall be kept as low as possible duringthe design, so that the longer the ups battery life is. When thebattery voltage is fixed, the batteries with small quantity andhigh voltage in series shall be selected instead of the batterieswith large quantity and low voltage in series. The battery voltageof some ups manufacturers is relatively high, because when thecapacity is fixed, the higher the voltage is, the smaller thecurrent is, and the thinner wire and the semiconductor with smallerpower can be selected, so as to reduce the cost of ups. The batteryvoltage of ups with capacity of 1kVA is generally 24-96v.

为了满足系统对带宽日益增长的需求，数据中心的主干光缆正在向更高芯数的方向发展。现在很多数据中心都在部署使用激光优化50μm多模光纤(OM3)的带状光缆来满足这个需求，以便在将来可升级到更高的数据传输速率，例如承载100G并行光信号。因带状光缆具有更加紧凑的光缆结构可以满足高密度连接的设计标准要求，以便获得大的线槽和空间利用率，很多数据中心正在向选用带状光缆过渡。例如一根144芯紧套光缆所占用的有效面积是一根同样芯数带状光缆的3.5倍。相对铜缆而言，一根216芯的水平光缆只占用与两到三根CAT6a UTP铜缆相似的有效面积。

现场链路损耗测试可为带状光缆安装后的性能提供量化的测量数据。安装后的链路测试之被认为是重要的测试，是因为其提供端到端，点到点或配线面板到配线面板的光功率损耗测试。

带状光缆的设计

当在数据中心部署24芯以上的主干光缆时，带状光缆正成为光缆设计的。典型的带状光缆由排列在中心束管中的12到216芯光纤构成。12芯光纤带由具有易识别性且符合TIA-598光纤色谱标准的12芯光纤组成。在室内数据中心应用中，使用特殊的阻燃外护套可以使光缆设计满足NFPA-262对带状水平光缆和UL-1666对带状垂直光缆的燃烧测试要求。图1为典型带状光缆的结构示意图。

带状光缆的端接

因受到12芯光纤带现场端接的限制，长期以来，设计者和安装人员一直对在数据中心中使用带状光缆心存芥蒂。

但随着诸如带纤分离工具、带纤分支组件和可现场安装的12芯光纤带连接器等一系列创新性产品的出现，现在我们可以使12芯光纤带与单芯、双芯连接器(如LC、SC连接器)或MTP连接器很容易连接。MTP连接器是一种类似SC单芯连接器大小的12芯插拔式光纤连接器。不带导向针的MTP连接器通常用于主干光缆，带有导向针的MTP连接器主要应用于互连跳线、分支跳线或MTP连接器模块。通过使用这种高密度连接器可以显著加速网络布线进程，错误小化并有效提高光纤配架面板的空间利用率。当今，预连接形式的MTP连接器应用已经非常普遍，既有用于与12芯带纤熔接的尾纤形式，又有用于主干光缆两端的预端接形式。我们还可以使用无需注胶和研磨的现场安装MTP连接器，5分钟内便可完成12芯带纤的现场端接。MTP连接器规格符合TIA/EIA-604-5互连性标准。
