技术领域
本公开案的技术涉及在分布式天线系统中通过光纤提供数字数据通信和射频（RF）通信。 
背景技术
随着对高速移动数据通信不断增长的需求，无线通信正快速发展。例如，将所谓的“无线保真”或“WiFi”系统和无线局域网（WLAN）正被部署在许多不同类型的区域（例如，咖啡店、机场、图书馆等）中。分布式天线系统与被称为“客户端”的无线装置通信，所述无线装置必须位于无线范围或“小区覆盖区域”内，以便与接入点装置通信。 
部署分布式天线系统的一个方法涉及射频（RF）天线覆盖区域（也称为“天线覆盖区域”）的使用。天线覆盖区域可具有例如在几米到高达二十米的范围中的半径。组合许多接入点装置形成天线覆盖区域阵列。因为天线覆盖区域各自覆盖小区域，所以通常每一天线覆盖区域只有几个用户（客户端）。这允许最小化无线系统用户间共享的RF带宽的量。可能需要在建筑或其他设施中提供天线覆盖区域以提供在建筑或设施内接入到客户端的分布式天线系统。然而，可能需要采用光纤来分配通信信号。光纤的益处包括增加的带宽。 
用于形成天线覆盖区域的一类分布式天线系统（称为“光纤载射频（Radio-over-Fiber）”或“RoF”）利用通过光纤发送的RF信号。所述系统可包括前端站，所述前端站光学耦接到多个远程天线单元，每一所述远程天线单元提供天线覆盖区域。远程天线单元可各自包括RF收发器，所述RF收发器耦接到天线以无线传输RF信号，其中远程天线单元通过光纤链路耦接到前端站。RF信号透过远程天线单元中的RF收发器。远程天线单元通过光至电（O/E）转换器将来自光纤下行链路的入射光学RF信号转换为电气RF信号，所述电气RF信号接着传递到RF收发器。RF收发器通过天线将电气RF信号转换为电磁信号，所述天线耦接到提供在远程天线单元中的RF收发器。天线还从天线覆盖区域中的客户端接收电磁信号（即，电磁辐射）并将所述电磁信号转换为电气RF信号（即，电线中的电气RF信号）。远程天线单元接着通过电至光（E/O）转换器将电气RF信号转换为光学RF信号。光学RF信号接着通过光纤上行链路发送到前端站。

具体实施方式中公开的实施方式包括分布式天线系统，所述分布式天线系统提供并支持射频（RF）通信服务和数字数据服务两者。RF通信服务还可通过光纤分配到客户端装置，例如远程通信单元。远程通信单元可支持无线通信服务、有线通信服务或无线通信服务和有线通信服务两者。数字数据服务可通过电气信号分配到客户端装置，例如远程通信单元。举例来说，数字数据服务的非限制性实例包括以太网、WLAN、全球微波接入互操作性（WiMax）、无线保真（WiFi）、数字用户线路（DSL）和长期演进技术（LTE）等。如果需要，电力也可通过电介质分配，以向远程通信装置和/或耦接到远程通信装置的客户端装置提供电力以用于操作，提供所述电介质以分配数字数据服务。例如，以所述方式，用于在分布式天线系统中传输数字数据信号的同一电介质还可用于向远程通信装置和/或耦接到远程通信装置的客户端装置提供电力。电力可通过所选电介质从两个或两个以上电源注入并切换，以为支持RF通信服务和数字数据服务两者的功耗组件分配电力。 
在论述分布式天线系统的实例前（分布式天线系统分配作为电气信号的数字数据服务和作为光学信号的RF通信服务），首先关于图1至图3描述示范性的基于光纤的分布式天线系统，所述系统提供RF通信服务，而未提供数字数据服务。从图4开始为在基于光纤的分布式天线系统中额外提供数字数据服务连同RF通信服务的各种实施方式。 
就这点来说，图1为基于光纤的分布式天线系统的实施方式的示意图。在此实施方式中，系统为基于光纤的分布式天线系统10，所述系统10配置为建立一或多个天线覆盖区域，以用于建立与定位在天线覆盖区域的RF范围中的无线客户端装置通信。基于光纤的分布式天线系统10提供RF通信服务（例如，蜂窝服务）。在此实施方式中，基于光纤的分布式天线系统10包括例如前端单元（HEU）的前端设备（HEE)12、一或多个远程天线单元（RAU）14和将HEE12光学耦接到RAU14的光纤16。RAU14为一种远程通信单元。一般来说，远程通信单元可支持无线通信或有线通信，或可支持两种。RAU14可支持无线通信，且也可支持有线通信。HEE12配置为通过下行链路电气RF信号18D从一个源或多个源（例如，作为实例的网络或载体）接收通信，并向RAU14提供这类通信。HEE12也配置为通过上行链 路电气RF信号18U将从RAU14接收的通信返回到一个源或多个源。就这一点来说，在此实施方式中，光纤16包括至少一个下行链路光纤16D来运载从HEE12传递到RAU14的信号，和至少一个上行链路光纤16U来运载从RAU14传递回HEE12的信号。可提供一个下行链路光纤16D和一个上行链路光纤16U以支持多个信道，每个信道使用波分复用（WDM），如在名为“Providing Digital Data Services in Optical Fiber-based Distributed Radio Frequency(RF)Communications Systems,And Related Components and Methods,”的第12/892,424号的美国专利申请案中所论述，所述申请案以引用的方式全部并入本文中。 
基于光纤的分布式天线系统10具有天线覆盖区域20，可关于RAU14部署所述天线覆盖区域20。RAU14的天线覆盖区域20形成RF覆盖区域21。HEE12适于执行或促进许多光纤载射频（RoF）应用（例如RF识别（RFID）、无线局域网（WLAN）通信或蜂窝电话服务）中的任何一个。例如，以移动装置的形式的客户端装置24展示在天线覆盖区域20内，所述移动装置例如可为蜂窝电话。客户端装置24可为能够接收RF通信信号的任何装置。客户端装置24包括适于接收和/或发送电磁RF信号的天线26（例如，无线卡）。 
继续参看图1，为通过下行链路光纤16D将电气RF信号传送到RAU14，以进而传送到由RAU14形成的天线覆盖区域20中的客户端装置24，HEE12包括电至光（E/O）转换器28。E/O转换器28将下行链路电气RF信号18D转换成下行链路光学RF信号22D，所述下行链路光学RF信号22D将通过下行链路光纤16D传送。RAU14包括光至电（O/E）转换器30以将接收的下行链路光学RF信号22D转换回电气RF信号，所述电气RF信号将通过RAU14的天线32无线传送到定位在天线覆盖区域20中的客户端装置24。 
同样地，天线32还配置为从天线覆盖区域20中的客户端装置24接收无线RF通信。就这点来说，天线32从客户端装置24接收无线RF通信，并将表示无线RF通信的电气RF信号传送到RAU14中的E/O转换器34。E/O转换器34将电气RF信号转换成上行链路光学RF信号22U，所述上行链路光学RF信号22U将通过上行链路光纤16U传送。在HEE12中提供的O/E转换器36将上行链路光学RF信号22U转换成上行链路电气RF信号，然后所述上行链路电气RF信号可作为上行链路电气RF信号18U传送回网络或其他源。在此实施 方式中的HEE12不能区别此实施方式中的客户端装置24的位置。客户端装置24可在由RAU14形成的任何天线覆盖区域20的范围中。

继续参看图2，服务单元37电气耦接到E/O转换器28，所述E/O转换器28从服务单元37接收下行链路电气RF信号18D，并将所述下行链路电气RF信号18D转换成对应的下行链路光学RF信号22D。在示范性实施方式中，E/O转换器28包括适于为本文中所述的RoF应用传递足够动态范围的激光器，且所述E/O转换器28视需要包括电气耦接到激光器的激光器驱动器/放大器。用于E/O转换器28的合适的激光器的实例包括（但不限于）激光二极管、分布式反馈（DFB）激光器、法布里-珀罗（FP）激光器和垂直腔表面发射激光器（VCSEL）。 
继续参看图2，HEE12也包括O/E转换器36，所述O/E转换器36电气耦接到服务单元37。O/E转换器36接收上行链路光学RF信号22U，并将所述上行链路光学RF信号22U转换成对应的上行链路电气RF信号18U。在示范性实施方式中，O/E转换器36为光检测器或电气耦接到线性放大器的光检测器。E/O转换器28和O/E转换器36组成“转换器对”35，如图2中所示。 
根据示范性实施方式，HEE12中的服务单元37可包括用于分别调节下行链路电气RF信号18D和上行链路电气RF信号18U的RF信号调节器单元40。服务单元37可包括用于向RF信号调节器单元40提供电气信号的数字信号处理单元（“数字信号处理器”）42，所述电气信号调制到RF载体上以产生所要的下行链路电气RF信号18D。数字信号处理器42也配置为处理由RF信号调节器单元40解调制上行链路电气RF信号18U而提供的解调信号。 HEE12也可包括用于处理数据和另外执行逻辑和计算操作的可选中央处理单元（CPU）44，和用于储存数据（例如将通过WLAN或其他网络传输的数据）的存储器单元46。 
继续参看图2，RAU14也可包括包含O/E转换器30和E/O转换器34的转换器对48。O/E转换器30将从HEE12接收的下行链路光学RF信号22D转换回下行链路电气RF信号50D。E/O转换器34将从客户端装置24接收的上行链路电气RF信号50U转换成将传送到HEE12的上行链路光学RF信号22U。O/E转换器30和E/O转换器34通过RF信号导向元件52（例如，循环器）电气耦接到天线32。RF信号导向元件52用于导向下行链路电气RF信号50D和上行链路电气RF信号50U，如下文所论述。根据示范性实施方式，天线32可包括任何类型的天线，所述任何类型的天线包括（但不限于）一或多个贴片型天线，例如在2006年8月16日申请的名为“Radio-over-Fiber Transponder With A Dual-Band Patch Antenna System,”的第11/504,999号美国专利申请案和在2006年6月12日申请的名为“Centralized Optical Fiber-Based Wireless Picocellular Systems and Methods,”的第11/451,553号美国专利申请案中公开的贴片型天线，所述两个申请案以引用的方式全部并入本文中。 
继续参看图2，基于光纤的分布式天线系统10也包括提供电力信号56的电源54。电源54电气耦接到HEE12以用于向HEE12中的功耗元件提供电力。在示范性实施方式中，电力线58贯穿HEE12并到达RAU14以向转换器对48中的O/E转换器30和E/O转换器34、可选的RF信号导向元件52（除非所述RF信号导向元件52为无源装置，例如循环器）和所提供的任何其他功耗元件提供电力。在示范性实施方式中，电力线58包括两根电线60和62，所述两根电线60和62运载单一电压且电气耦接到RAU14处的DC功率转换器64。DC功率转换器64电气耦接到转换器对48中的O/E转换器30和E/O转换器34，且DC功率转换器64将电力信号56的电压或电平变化到RAU14中功耗组件所要求的（一或多个）功率电平。在示范性实施方式中，取决于由电力线58运载的电力信号56的类型，DC功率转换器64为DC/DC功率转换器或AC/DC功率转换器。在另一示范性实施方式中，电力线58（虚线）从电源54而不是从HEE12或穿过HEE12直接延行到RAU14。在另一示范性实施方式中，电力线58包括两根以上的电线且可运载多电压。 
提供图3来提供如何将基于光纤的分布式天线系统部署在室内的进一步示范性图式。图3为使用基于光纤的分布式天线系统的建筑基础结构70的部分示意剖示图。系统可为图1和图2的基于光纤的分布式天线系统10。建筑基础结构70一般表示任何类型的建筑，基于光纤的分布式天线系统10可部署在所述建筑中。如前文关于图1和图2所述，例如，基于光纤的分布式天线系统10合并HEE12以向建筑基础结构70内的覆盖区域提供各种类型的通信服务。举例来说，如下更详细所述，在此实施方式中，基于光纤的分布式天线系统10配置为接收无线RF信号并将RF信号转换成通过光纤16传送到多个RAU14的RoF信号。在此实施方式中，基于光纤的分布式天线系统10可为（例如）在建筑基础结构70内提供无线服务的室内分布式天线系统（IDAS）。例如，这些无线信号可包括蜂窝服务、例如RFID跟踪的无线服务、无线保真（WiFi）、局域网（LAN）、WLAN、公共安全、无线建筑自动化和上述各项的组合。 
继续参看图3，在此实施方式中，建筑基础结构70包括第一（底层）楼层72、第二楼层74和第三楼层76。由HEE12通过总配线架78为楼层72、楼层74和楼层76提供服务以在建筑基础结构70中提供天线覆盖区域80。为了说明的简洁性，图3中只图示楼层72、楼层74和楼层76的天花板。在示范性实施方式中，干线电缆82具有若干不同段，所述不同段促进大量RAU14在建筑基础结构70中的布置。每一RAU14进而在天线覆盖区域80中服务自身的覆盖区域。干线电缆82可包括（例如）直立电缆84，所述直立电缆84将所有下行链路光纤16D和上行链路光纤16U运载到HEE12并从所述HEE12运载所有光纤。直立电缆84可通过互连单元（ICU）85来布线。ICU85可提供作为图2中的电源54的一部分或与所述电源54分开。ICU85还可配置为通过电力线58向RAU14提供电源，如图2中所示且如上所述，电力线58提供在方阵电缆87（或作为其他实例的尾电缆或家用（home-run）系绳电缆）内并与下行链路光纤16D和上行链路光纤16U一起分配到RAU14。干线电缆82可包括一或多个多电缆（MC）连接器，所述MC连接器适用于将选择的下行链路光纤16D和上行链路光纤16U连同电力线一起连接到若干光纤电缆86。 
干线电缆82使多个光纤电缆86能够分配遍及建筑基础结构70（例如，固定到每一楼层72、74、76的天花板或其他支撑表面），以为第一楼层72、第二楼层74和第三楼层76提供天线覆盖区域80。在示范性实施方式中，HEE12位于建筑基础结构70内（例如，在机柜或控制室），而在另一示范性实施方式中，HEE12可位于建筑基础结构70的外的远程位置处。基站收发站（BTS）88可由第二方（例如，蜂窝服务提供商）提供，所述BTS88连接到HEE12且可与HEE12协同定位或独立于所述HEE12定位。BTS为任何站或信号源，所述站或信号源向HEE12提供输入信号并从HEE12接收返回信号。在典型蜂窝系统中，例如，在多个远程位置处部署多个BTS以提供无线电话覆盖。每一BTS为对应的小区服务，且当移动客户端装置进入小区时，BTS与移动客户端装置通信。每一BTS可包括至少一个无线电收发机，来实现与在相关小区内操作的一或多个用户单元的通信。再如，也可使用无线中继器或双向放大器来代替BTS为对应的小区服务。或者，作为其他实例，可由中继器、微微小区或毫微微蜂窝提供无线电输入。 
图1至图3中和上述的基于光纤的分布式天线系统10提供HEE12与RAU14之间的点对点通信。同样多点架构也是可能的。关于图1至图3，每一RAU14通过独特的下行链路和上行链路光纤对与HEE12通信，以提供点对点通信。每当将RAU14安装在基于光纤的分布式天线系统10中时，RAU14连接到独特的下行链路和上行链路光纤对，所述光纤对连接到HEE12。下行链路光纤16D和上行链路光纤16U可提供在光纤电缆中。多个下行链路和上行链路光纤对可提供在光纤电缆中以通过常用光纤电缆来为多个RAU14服务。举例来说，参看图3，安装在给定楼层72、74或76上的RAU14可由同一光纤16服务。就这点来说，光纤16可具有多个节点，在所述节点处，独特的下行链路和上行链路光纤对可连接到给定RAU14。可提供一个下行链路光纤16D以支持多个信道，每个信道使用波分复用（WDM），如在名为“Providing Digital Data Services in Optical Fiber-based Distributed Radio Frequency(RF)Communications Systems,And Related Components and Methods,”的第12/892,424号的美国专利申请案中所论述，所述申请案以引用的方式全部并入本文中。还在第12/892,424号美国专利申请案中公开 WDM和频分复用（FDM）的其他选项，可在本文中公开的任一实施方式中使用任一其他选项。 
HEE12可配置为支持所要的任何频率，所述频率包括（但不限于）美国联邦通信委员会（US FCC）和加拿大工业频率（上行链路824MHz到849MHz和下行链路869MHz到894MHz）、US FCC和加拿大工业频率（上行链路1850MHz到1915MHz和下行链路1930MHz到1995MHz）、US FCC和加拿大工业频率（上行链路1710MHz到1755MHz和下行链路2110MHz到2155MHz）、US FCC频率（上行链路698MHz到716MHz和776MHz到787MHz和下行链路728MHz到746MHz）、EU R和TTE频率（上行链路880MHz到915MHz和下行链路925MHz到960MHz）、EU R和TTE频率（上行链路1710MHz到1785MHz和下行链路1805MHz到1880MHz）、EU R和TTE频率（上行链路1920MHz到1980MHz和下行链路2110MHz到2170MHz）、USFCC频率（上行链路806MHz到824MHz和下行链路851MHz到869MHz）、US FCC频率（上行链路896MHz到901MHz和下行链路929MHz到941MHz）、US FCC频率（上行链路793MHz到805MHz和下行链路763MHz到775MHz）和US FCC频率（上行链路和下行链路2495MHz到2690MHz）。 
可能需要为客户端装置提供数字数据服务和RF通信服务两种。举例来说，可能需要在建筑基础结构70中向位于所述建筑基础结构70中的客户端装置提供数字数据服务和RF通信服务。有线装置和无线装置可定位在建筑基础结构70中，所述有线装置和无线装置配置为接入数字数据服务。数字数据服务的实例包括（但不限于）以太网、WLAN、全球微波接入互操作性（WiMax）、无线保真（Wireless Fidelity,WiFi）、数字用户线路（Digital Subscriber Line,DSL）和长期演进技术（LTE）等。可支持以太网标准，所述以太网标准包括（但不限于）100兆每秒（Mbs）（也就是，高速以太网）或千兆（Gb）以太网或万兆（10G）以太网。数字数据装置的实例包括（但不限于）有线服务器和无线服务器、无线接入点（WAP）、网关、台式电脑、集线器、交换机、远程无线电头端（RRH）、基带单元（BBU）和毫微微蜂窝。可提供单独的数字数据服务网络以向数字数据装置提供数字数据服务。 
就这点来说，图1到图3中的基于光纤的分布式天线系统10可改进为通过图1到图3中的基于光纤的分布式天线系统10中的光纤提供所述数字数据 服务。RF通信服务和数字数据服务可通过光纤分配到客户端装置，例如RAU。数字数据服务可通过光纤分配，所述光纤独立于分配RF通信服务的光纤。或者，数字数据服务以及RF通信服务都可基于光纤的分布式天线系统中通过常用光纤分配。举例来说，数字数据服务和RF通信服务可通过常用光纤凭借WDM在不同波长下分配和/或凭借FDM在不同频率下分配。在同在申请中的美国专利申请案第[HI10-043]号、第61/330,385号、第[HI10-043P]号、第[HI10-045-P2]号、第61/330,386[HI10-045-P]号和第12/892,424[HI10-045]号中公开在基于光纤的分布式天线系统中提供数字数据服务的实例，所述全部申请案全文以引用的方式并入本文中。 
然而，可能需要通过电气通信介质在分布式天线系统中提供数字数据服务以作为电气信号，而不是通过光纤传送的光学信号。就这点来说，将不需要将用于下行链路服务的数字数据服务从电气信号转换为光学信号以用于通过光纤分配到RAU，其中用于数字数据服务的光学信号转换回电气信号，反之亦然，以用于上行链路分配。举例来说，可能更需要通过电气信号介质分配数字数据服务。举例来说，分布式天线系统的安装位置可能已经包括通过现有电气信号介质分配的数字数据服务。当整合或添加将通过光纤分配的RF通信服务时，将仅需要部署用于RF通信服务的光纤。当在分布式天线系统中整合数字数据服务和RF通信服务的分配时，可使用或重复使用现有电气信号介质。就这点来说，可提供分布式天线系统以提供数字数据服务和RF通信服务。例如，如果需要，可通过改进或变更图1到图3中的基于光纤的分布式天线系统10来提供所述分布式天线系统。RF通信服务和数字数据服务可通过光纤分配到客户端装置，例如RAU。数字数据服务可通过独立于分配RF通信服务的光纤的电气信号介质来分配。 
就这点来说，在一个实施方式中，图4为示范性实施方式的示意图，所述实施方式通过电气信号和光纤将数字数据服务和RF通信服务提供到分布式天线系统90中的RAU。分布式天线系统90包括一些光学通信组件，所述光学通信组件在此实施方式中提供在图1到图3的基于光纤的分布式天线系统10中。图4中用图1至图3的通用元件符号图示这些通用组件。如图4中所示，提供HEE12。HEE12从BTS88接收下行链路电气RF信号18D。如先前所论述，HEE12将下行链路电气RF信号18D转换成将分配到RAU14的下行 链路光学RF信号22D。HEE12也配置为将从RAU14接收的上行链路光学RF信号22U转换成上行链路电气RF信号18U，所述上行链路电气RF信号18U将提供到BTS88和连接到BTS88的网络93上。可提供接线板92以接收配置为运载下行链路光学RF信号22D和上行链路光学RF信号22U的下行链路光纤16D和上行链路光纤16U。如上所论述和图3中所示，下行链路光纤16D和上行链路光纤16U可一起捆绑在一或多个直立电缆84中且可提供到一或多个ICU85。 
为在此实施方式中的分布式天线系统90中提供数字数据服务，提供数字数据服务控制器94（也称为“DDS控制器”或“DDSC”）。DDS控制器94为配置为通过通信链路、接口或其他通信信道或线路提供数字数据服务的控制器或其他装置，所述通信链路、接口或其他通信信道或线路可为有线的、无线的或两者的组合。在此实施方式中，以通过数字数据服务线路99传送的电气数字信号的形式从DDS交换机96提供向分布式天线系统90提供的数字数据服务。在此实施方式中，DDS控制器94不含媒体转换器，因为在此实施方式中数字数据服务的电气信号不转换为光学信号。DDS控制器94可包括微处理器、微控制器或专用电路。或者，DDS控制器94可简单地包括接线板或模块以允许从DDS交换机96到DDS控制器94的数字数据服务连接。 
继续参看图4，在此实施方式中，DDS控制器94配置为通过来自数字数据服务交换机96的数据服务线路99将来自DDS交换机96的下行链路电气数字信号（或下行链路电气数字数据服务信号）98D转换为下行链路电气数字信号（或下行链路电气数字数据服务信号）100D，所述下行链路电气数字信号100D可通过下行链路电介质102D传送到RAU14。在一个实施方式中，下行链路电介质102D可为电介质以太网电缆，例如，作为非限制性实例的种类5（CAT5）、种类5e（CAT5e）、种类6（CAT6）和种类7（CAT7）电缆，所述电缆含铜或其他金属或金属合金线对。DDS控制器94还配置为通过上行链路电介质102U从RAU14接收上行链路电气数字信号100U。以所述方式，可通过作为分布式天线系统90的部分的独立于光纤16D和光纤16U的电介质102D和电介质102U提供数字数据服务，以提供除RF通信服务之外的数字数据服务。如下所论述，就这点来说，取决于客户端装置的配置，定位 在RAU14处的所述客户端装置可接入这些数字数据服务和/或RF通信服务。 
如果在安装分布式天线系统前电介质已经存在，那么通过电介质提供数字数据服务可能尤为理想的或有用的。电介质的距离需足以支持所要求的电气数字信号标准。举例来说，可额定种类X（CATx）电介质电缆以支持约1Gbps高达100米的数据传输。如果分布式天线系统可支持电介质的距离限制，那么分布式天线系统可使用所述电介质而不是另一介质（例如，光纤）来分配数字数据服务。然而，通过提供光纤作为分配介质以用于RF通信服务，可为RF通信服务提供增强的服务，包括但不限于例如，增加的分配距离和带宽、低噪音和WDM。 
举例来说，图5图示图4的建筑基础结构70，但具有除分布式天线系统90中的RF通信服务外的数字数据服务和数字客户端装置的说明性实例，可向客户端装置提供所述数字数据服务和数字客户端装置。如在图5中所示，示范性数字数据服务包括WLAN106、毫微微蜂窝108、网关110、基带单元（BBU）112、远程无线电头端（RRH）114和服务器116。 
返回参看图4，在此实施方式中，下行链路电介质102D和上行链路电介质102U提供在电缆104中，所述电缆104与ICU85接口连接。作为非限制性实例，电缆104可为方阵电缆或家用电缆。在此实施方式中，ICU85是任选的并提供公共点，如果需要，运载电气数字信号的下行链路电介质102D和上行链路电介质102U在所述公共点中可与运载RF光学信号的下行链路光纤16D和上行链路光纤16U捆绑在一起。或者，电缆104可不与下行链路光纤16D和上行链路光纤16U捆绑在一起或可不运载下行链路光纤16D和上行链路光纤16U。可提供一或多个电缆104，所述电缆104含有布线并提供到RAU14的用于RF通信服务的下行链路光纤16D和上行链路光纤16U和用于数字数据服务的下行链路电介质102D和上行链路电介质102U。在电缆104中可提供服务或光纤类型的任何组合。举例来说，电缆104可能包括用于RF通信服务和/或数字数据服务的单模光纤和/或多模光纤。 
在2009年5月15日申请的名为“Power Distribution Devices,Systems,and Methods For Radio-Over-Fiber(RoF)Distributed Communication,”的第12/466,514号美国专利申请案和在2010年5月2日申请的名为“Power  Distribution in Optical Fiber-based Distributed Communication Systems Providing Digital Data and Radio-Frequency(RF)Communication Services,and Related Components and Methods,”第61/330,385号美国临时专利申请案（所述两个申请案以引用的方式全部并入本文中）中描述ICU的实例，所述ICU可在分布式天线系统90中提供以分配用于RF通信服务的下行链路光纤16D和上行链路光纤16U和用于数字数据服务的下行链路电介质102D和上行链路电介质102U。 
继续参看图4，一些RAU14可连接到接入单元（AU）118，所述接入单元118可为支持数字数据服务的接入点（AP）或其他装置。AU118也可直接连接到HEE12。图示AU118，但AU118可为支持数字数据服务的任何其他装置。在AU的实例中，AU118提供对由DDS交换机96提供的数字数据服务的接入。这是因为通过电缆104和RAU14将运载下行链路电气数字信号100D和上行链路电气数字信号100U的下行链路电介质102D和上行链路电介质102U从DDS交换机96和DDS控制器94提供到AU118。数字数据客户端装置可接入AU118以接入通过DDS交换机96提供的数字数据服务。AU118可被视为任何类型的远程通信单元，且AU118可包括或可不包括用于无线通信的天线。如果AU118配置有天线，那么AU118可被视为另一类型的远程天线单元。 
远程通信装置（例如RAU、AU和耦接到所述远程通信装置的客户端装置）可能需要电力来操作并提供RF和/或数字数据服务。借由通过作为分布式天线系统的部分的电介质提供数字数据服务，电介质还可用于向这些远程通信装置分配电力。与在远程客户端处局部地提供单独的电源或提供单独介质以用于分配电力相反，这可为向远程数字数据服务客户端提供电力的方便的方法。 
举例来说，（例如）通过或凭借作为实例的ICU85分配到图4中的RAU14的电力还可用于向定位在分布式天线系统90中的RAU14处的AU118提供电力。就这点来说，任选ICU85可配置为向RAU14和AU118两者提供电力。电源可位于ICU85内，但也可位于ICU85外，并且所述电源可通过电源线120提供，如在图4中所示。如在下文更详细所论述，在此实施方式中，ICU85可配置为在同一电介质（例如，图4中的下行链路电介质102D）上分 配电力，如同用于分配数字数据服务一样。ICU85可接收交流（AC）或直流（DC）电。ICU85可接收110伏特（V）到240V的AC或DC电。ICU85可配置为产生任何所需电压电平和功率电平。功率电平基于RAU14的数量和由图4中的RAU14和连接到RAU14的任何数字装置支持的预期负载。可能进一步希望在ICU85中提供额外电力管理特征。举例来说，可提供一或多个电压保护电路。 
图6为图4的RAU14中的示范性内部组件的示意图，以进一步图示用于RF通信的下行链路光纤16D和上行链路光纤16U、用于数字数据服务的下行链路电介质102D和上行链路电介质102U和电力可如何提供到RAU14和可如何分配在RAU14中。如图6中所示，图示电缆104，所述电缆104含有用于RF通信的下行链路光纤16D和上行链路光纤16U和用于数字数据服务的下行链路电介质102D和上行链路电介质102U。如下文将关于图7和图8更详细地论述，还通过下行链路电介质102D和上行链路电介质102U从ICU85或其他组件运载电力以向RAU14中的功耗组件提供电力。可通过ICU85处的下行链路电介质102D和上行链路电介质102U提供或从分布式天线系统90中的另一位置或组件处的另一电源或源提供电力。举例来说，用于向RAU14提供电力的电源可在（例如）图4中的DDS控制器94或DDS交换机96处提供。 
用于RF通信的下行链路光纤16D和上行链路光纤16U和用于数字数据服务的下行链路电介质102D和上行链路电介质102U进入RAU14的外壳124中。也如图2中所示和前文所论述，用于RF通信的下行链路光纤16D和上行链路光纤16分别布线到O/E转换器30和E/O转换器34，并布线到天线32。用于数字数据服务的下行链路电介质102D和上行链路电介质102U布线到作为RAU14的部分而提供的数字数据服务接口126，以通过端口128提供数字数据服务的接入，所述数字数据服务接口126将在下文详细描述。通过下行链路电介质102D和上行链路电介质102U运载的电力向O/E转换器30和E/O转换器34并向数字数据服务接口126提供电力。就这点来说，下行链路电介质102D耦接到电压控制器130，所述电压控制器130调节正确电压并为O/E转换器30和E/O转换器34提供所述正确电压，并为RAU14中的数字数据服务接口126和其他电路提供所述正确电压。 
在此实施方式中，数字数据服务接口126配置为分配下行链路电介质102D上的下行链路电气数字信号100D，以使得下行链路电气数字信号132D可通过端口128接入。数字数据服务接口126还配置为将通过端口128接收的上行链路电气数字信号132U转换成上行链路电气数字信号100U，所述上行链路电气数字信号100U将提供回DDS94（见图4）。就这点来说，可在数字数据服务接口126中提供DDS控制器134以提供这些分配和控制。DDS控制器134将下行链路电介质102D上的下行链路电气数字信号100D转换成下行链路电气数字信号132D。可在下行链路电气数字信号100D分配到端口128前在信号处理器136中提供下行链路电气数字信号100D的任何信号处理。DDS控制器134还将通过端口128接收的上行链路电气数字信号132U转换成上行链路电气数字信号100U，所述上行链路电气数字信号100U将提供回DDS控制器94。在从连接到端口128的数字客户端传送的上行链路电气数字信号分配在下行链路电介质102D上之前，可在任选信号处理器138中提供所述上行链路电气数字信号的任何信号处理。就这点来说，来自下行链路电介质102D的电力通过电压控制器130提供电力到DDS控制器134的任何功耗组件。 
由于电力提供到RAU14和数字数据服务接口126，这也为通过端口128为连接到RAU14的数字装置提供电力提供了机会。就这点来说，在此实施方式中，如在图6中所示，任选电源接口140也可提供在数字数据服务接口126中。电源接口140可配置为通过电压控制器130从下行链路电介质102D接收电力，并且电源接口140还配置为使电力可通过端口128接入。以这种方式，如果客户端装置含有兼容连接器以连接到端口128，那么将不仅可接入数字数据服务，而且还可通过相同端口128接入来自电力线58的电力。或者，电源接口140可耦接到与用于数字数据服务的端口128分开的端口。 
举例来说，如果通过以太网提供数字数据服务，那么电源接口140可提供为以太网供电（PoE）接口。端口128可配置为接收与作为实例的PoE或PoE+兼容的RJ-45以太网连接器。以这种方式，连接到端口128中的以太网连接器将能够将以太网数字数据服务接入到下行链路电介质102D和上行链路电介质102U再到DDS控制器94，并能够将所述以太网数字数据服务从下行链路电介质102D和上行链路电介质102U接入到DDS控制器94，并且所述 以太网连接器还能够通过由下行链路电介质102D提供的电缆104接入ICU85分配的电力。 
进一步地，HEE12可包括使用由HEE12支持的通信的DDS控制器134的低阶控制和管理。举例来说，DDS控制器134可通过运载（例如）RF通信服务的上行链路光纤16U将功能数据（例如，通电、接收光学数字数据等）报告给HEE12。RAU14可包括微处理器，所述微处理器与DDS控制器134通信，以接收所述数据并通过上行链路光纤16U将所述数据传送到HEE12。 
如上所论述，代替在ICU85（或其他装置或其他电源）到RAU14和/或AU118之间提供单独电力线，可通过电介质102D和/或电介质102U提供供应到RAU14和/或AU118的电力，所述电介质102D和/或电介质102U用于传送电气数字信号100D、电气数字信号100U。供应到RAU14和AU118的电力可用于向用于RF通信服务的功耗组件提供电力。通过电介质102D和/或电介质102U供应到RAU14和/或AU118的电力还可用于给远程客户端供电，例如作为实例的PoE和PoE+兼容装置（也称为电源供应设备（PSE）），所述远程客户端连接到RAU14或AU118的端口128（见图6）。以这种方式，RAU14和/或AU118可能不需要用于这些装置和/或远程客户端内提供的功耗组件的本地电源，所述装置和/或远程客户端耦接到RAU14和/或AU118并从RAU14和/或AU118接收电力。 
就这点来说，提供到RAU14和/或AU118的电力可作为运载电气数字信号100D和电气数字信号100U的（交流（AC）信号）的同一介质、媒体或线路上的直流（DC）而添加。或者，可通过单独介质、媒体或线路（例如，作为实例的单独双绞线对）提供电力，所述介质、媒体或线路不运载电气数字信号100D和/或电气数字信号100U。所述情况中的每一情况可取决于电介质102D、电介质102U的具体配置和针对电介质102D、电介质102U配置或提供的标准和/或数据速率。 
就这点来说，图7图示电介质102D、电介质102U的一个实施方式以提供两个电气数字信号100D、100U并向RAU14和/或AU118提供电力。在下文更详细地论述的所述实施方式中，电介质102D、电介质102U为以太网电缆142，在所述实例中特别地为CAT5/CAT6/CAT7电缆。如在图7中所示，在此实施方式中，以太网电缆142包含在具有下行链路光纤16D、上行链路光 纤16U的电缆104内。如先前所论述，以太网电缆142将运载电气数字信号100D、电气数字信号100U以用于数字数据服务。下行链路光纤16D、上行链路光纤16U将运载光学RF信号22D、光学RF信号22U以用于RF通信服务。如在图7中所示，如果以太网电缆142配置为在（例如）DDS交换机96（图4）处以10BASE T（10Mbps）、100BASE T（100Mbps）、1Gps或10Gps的数据速率使用，那么对1和2和对3和6运载电气数字信号100D、电气数字信号100U。其他两对以太网电缆142（对4和5和对7和8）为未使用电介质143、电介质144，并可用于独立于电气数字信号100D、电气数字信号100U通过电介质143、电介质144运载电力。所述电力可通过DDS交换机96、DDS控制器94、ICU85或在接入电力和/或电源的任何其他装置或位置处提供在未使用的电介质143、电介质144上。 
或者，再如，继续参看图7，如果以太网电缆142配置为在DDS交换机96（图4）处以1000BASE T（1Gbps）的数据速率使用，那么所有对配置为运载电气数字信号100D、电气数字信号100U。可根据所使用的标准（例如根据IEEE802.3af-2003的PoE和根据IEEE802.3af-2003的PoE+）控制配置为提供在电介质102D、电介质102U上的电力。例如，与独立于电气数字信号100D、电气数字信号100U提供电力相比，可将电力添加到两（2）对双绞线（例如，1、2、3和6或4、5、7和8）或所有对（例如，1、2、3、6、4、5、7和8）例如以用于PoE兼容，所述对运载电气数字信号100D、电气数字信号100U。仅通过双绞线对1和2和双绞线对3和6提高电力称为“模式A”。通过双绞线对4和5和双绞线对7和8提高电力称为“模式B”。IEEE802.3af-2003可使用模式A或模式B提供电力。IEEE802.af-2009可使用模式A、模式B或同时使用模式A和模式B提供电力。然而，对在分布式天线系统90中的设备来说哪些双绞线对组合运载电力可能是未知的。对分布式天线系统90来说所述配置为透明的以避免配置问题可能更可取。进一步地，还可能需要通过电介质102D、电介质102U提供额外电力以用于RF通信服务组件，例如转换器。但是，问题在于不知道以太网电缆142的双绞线对中哪些运载用于PoE兼容装置的电力的双绞线对。这是因为，将不知道可用于针对RF通信服务从RF单独电源提供单独电力的哪些双绞线对。 
如在图8中所示，还为了具有通过电介质102D、电介质102U从ICU85或其他电源提供电力到RAU14和/或AU118中的RF通信服务组件的能力，对电介质102D、电介质102U提供以用于给连接到端口128（例如，PoE）的数字客户端装置供最的电力定向为仅通过相同的两对以太网电缆142双绞线对运载。以所述方式，其他两对以太网电缆142双绞线对可用于运载电力以用于RF通信服务功耗组件。否则，如果用于RF通信服务和数字数据客户端两个的电力仅置于一（1）对电介质102D、电介质102U双绞线对上，那么可能不能提供足够的电力以用于RF通信服务和连接到端口128的数字数据客户端。举例来说，可能需要提供三十（30）瓦特（W）电力到端口128并提供六十（60）W电力到RAU14和/或AU118以用于组件，所述组件用于提供RF通信服务。可能不能仅对一（1）对电介质102D、电介质102U双绞线对提供九十（90）W电力。 
转向图8，提供来自DDS控制器94（图4）的电介质102D、电介质102U（有时在本文中被称为电气输入链路）。如先前所述，电介质102D、电介质102U运载到RAU14和/或AU118以通过电气数字信号100D、电气数字信号100U提供数字数据服务并可视情况还具有在电介质102D、电介质102U上传送的电力信号。如图8中所示，数字数据服务客户端可连接到端口128以接收数字数据服务。并且，如先前所论述，数字数据服务客户端可无线接收数字数据服务。将通过电气数字信号100D、电气数字信号100U提供的数字数据服务提供到电介质102D、电介质102U上运载的任何电力信号可通过的RAU14和/或AU118。 
继续参看图8，如在图8中所示，在所述实施方式的ICU85中提供电路和（尤其是）二极管电桥电路145，所述电路和二极管电桥电路耦接到每一电介质102D、电介质102U双绞线对中。二极管电桥电路145补偿来自DDS控制器94的置于任何电介质102D、电介质102U双绞线对上的电力的极性变化，并将所述电力仅导向较低的两对146电介质102D、电介质102U。就这点来说，较低两对146形成电力输出，在所述情况下，用于ICU85的输出。因此，二极管电桥145将电介质102D、电介质102U的电气输入链路耦接到以较低两对146中的一对或两对的形式呈现的至少一个电力输出。可能未定义极性，且因此接收器可能需要能够接受任一模式下的极性。以所述方式， 较高两对147电介质102D、电介质102U不运载来自DDS控制器94的电力。就这点来说，较高两对147形成电气通信输出（在所述情况下，用于ICU85的输出），并配置为向RAU14，尤其是向RAU14的通信接口分配数字数据信号。如果需要，较高两对147电介质102D、电介质102U可用于运载来自单独电源148的额外电力，所述额外电力将导向较高两对147电介质102D、电介质102U上。所述额外电力可用于提供电力以用于RAU14和/或AU118中的RF功耗组件。可在RAU14和/或AU118中提供电力分接头149以分接来自较高电介质102D、电介质102U双绞线对147的电力，以用于向RF通信服务组件提供电力，同时电力可通过较低电介质102D、电介质102U双绞线对146单独向端口128提供，以用于待供电的数字数据客户端。 
在分布式天线系统中提供数字数据服务并为数字数据服务分配电力的其他配置是可能的。举例来说，图9为另一示范性实施方式的示意图，所述实施方式在分布式天线系统中提供数字数据服务，所述分布式天线系统还配置为提供RF通信服务。就这点来说，图9提供分布式天线系统150。分布式天线系统150可与图4中的分布式天线系统90中提供的通用组件类似，并可包括图4中的分布式天线系统90中提供的通用组件。在此实施方式中，DDS控制器94与HEE12协同定位而不是独立于HEE12提供。用于分配来自DDS交换机96的数字数据服务的下行链路电介质102D和上行链路电介质102U也连接到接线板92。类似于图2，用于RF通信的下行链路光纤16D和上行链路光纤16U和用于数字数据服务的下行链路电介质102D和上行链路电介质102U随后布线到ICU85。 
用于RF通信的下行链路光纤16D和上行链路光纤16U和用于数字数据服务的下行链路电介质102D和上行链路电介质102U可提供在常用电缆中（例如电缆104），或提供在单独电缆中。进一步地，如在图9中所示，单独访问单元（AU）118可独立于RAU14提供，而不是与RAU14整合，如在图4中所示。单独AU118可配置为含有图6中的DDS控制器134。每一AU118还可包括天线152（也图示在图4中）以提供代替或除了通过RAU14通过端口128的有线服务之外的无线数字数据服务。 
本文中所公开的并预期的分布式天线系统不受任何特定类型的分布式天线系统或特定设备的限制。举例来说，图10为示范性HEE158的示意图， 所述HEE158可与本文中所公开的任何分布式天线系统一起使用，包括但不限于分布式天线系统10、分布式天线系统90、分布式天线系统150。在此实施方式中，HEE158配置为通过光纤分配RF通信服务。在此实施方式中，如在图10中所示，HEE158包括前端控制器（HEC）160，所述前端控制器160管理HEE158组件的功能并（例如）通过接口（例如，RS-232端口162、通用串行总线（USB）端口164和以太网端口168）与外部装置通信。HEE158可通过BTS输入170和BTS输出172连接到多个BTS、收发器等等。BTS输入170为下行链路连接，且BTS输出172为上行链路连接。各BTS输入170连接到定位在HEE158中的下行链路BTS接口卡（BIC）174，且各BTS输出172连接到也定位在HEE158中的上行链路BIC176。下行链路BIC174配置为接收来自BTS输入170的入射或下行链路RF信号，并将下行链路RF信号分成将传送到RAU14的副本，如在图2中所示。上行链路BIC176配置为接收来自RAU14的组合的外送或上行链路RF信号，并将上行链路RF信号分成个别BTS输入172，以作为返回通信路径。 
继续参看图10，在此实施方式中，下行链路BIC174连接到中间平面接口卡178板。上行链路BIC176也连接到中间平面接口卡178。下行链路BIC174和上行链路BIC176可提供在印刷电路板（PCB）中，所述PCB包括可直接插入中间平面接口卡178的连接器。中间平面接口卡178与多个光学接口卡（OIC）180电气通信，所述OIC180通过下行链路光纤16D和上行链路光纤16U和下行链路BIC174和上行链路BIC176在RAU14之间提供光至电通信接口，且反之电至光通信接口。OIC180包括如关于图1所论述的E/O转换器28，所述E/O转换器28将来自下行链路BIC174的电气RF信号转换成光学RF信号，然后，所述光学RF信号通过下行链路光纤16D传送到RAU14，并随后传送到客户端装置。OIC180也包括如图1中的O/E转换器36，所述O/E转换器36通过上行链路光纤16U将从RAU14传送的光学RF信号转换到HEE158，并随后转换到BTS输出172。 
继续参看图10，在此实施方式中，各OIC180支持多达三个（3）RAU14。OIC180也可提供在PCB中，所述PCB包括连接器，所述连接器可直接插入中间平面接口卡178中以将OIC180中的链路耦接到中间平面接口卡178。OIC180可由一或多个光学接口卡（OIC）组成。以所述方式，在此实施方 式中，HEE158是可扩展的以支持多达三十六（36）个RAU14，因为HEE158可支持多达十二（12）个OIC180。如果HEE158支持少于三十六（36）个RAU14，那么HEE158可包括少于十二（12）个OIC180，且少于十二（12）个OIC180可插入中间平面接口卡178中。在此实施方式中，为由HEE158支持的每三个（3）RAU14提供一个OIC180。如果需要在初始配置上支持额外RAU14，那么也可将OIC180添加到HEE158并连接到中间平面接口卡178。继续参看图10，也可提供HEU160，所述HEU160配置为能与下行链路BIC174、上行链路BIC176和OIC180通信以提供各种功能，包括本文中所提供的放大器和衰减器的配置。 
图11为另一示范性分布式天线系统200的示意图，所述分布式天线系统200可根据本文中所公开的实施方式使用以提供RF通信服务和数字数据服务。在此实施方式中，分布式天线系统200包括用于分配RF通信服务的光纤。分布式天线系统200还包括用于分配数字数据服务的电介质。 
继续参看图11，在此实施方式中，分布式天线系统200由三个（3）主要组件组成。在此实施方式中，以无线电接口模块（RIM）202(1)-202(M)形式提供的一或多个无线电接口提供在HEE204中以在光学转换成下行链路光学RF通信信号前接收并处理下行链路RF通信信号206D(1)-206D(R)。下行链路RF通信信号206D(1)-206D(R)的处理可包括先前在图1到图3中的HEE12中所描述的任何处理。符号“1-R”和符号“1-M”指示可分别提供任何数目的参考组件，即1-R和1-M。如将在下文更详细地所论述，HEE204配置为接收多个RIM202(1)-202(M)以作为模块组件，所述模块组件在HEE204中可容易地安装和移除或替换。在一个实施方式中，HEE204配置为支持例如多达四个（4）RIM202(1)-202(M)。 
各RIM202(1)-202(M)可设计为支持特殊类型的无线电源或特定范围的无线电源（即，频率）以提供配置HEE204和分布式天线系统200的灵活性以支持所要无线电源。举例来说，一个RIM202可配置为支持个人通信服务（PCS）无线电频段。另一RIM202可配置为支持700MHz的无线电频段。在此实例中，通过包含这些RIM202，HEE204将配置为支持并分配PCS和LTE700无线电频段上的RF通信信号。RIM202可提供在HEE204中，所述RIM202支持任何所要的频段，包括但不限于US蜂窝频段、个人通信服务 （PCS）频段、先进无线服务（AWS）频段、700MHz的频段、全球移动通信系统（GSM）900、GSM1800和全能移动电信系统（UMTS）。RIM202可提供在HEE204中，所述RIM202支持任何所要的无线技术，包括但不限于码分多址接入（CDMA）、CDMA200、lxRTT、纯数据演进（EV-DO）、UMTS、高速分组接入（HSPA）、GSM、通用分组无线服务（GPRS）、增强型数据GSM环境（EDGE）、时分多址接入（TDMA）、长期演进（LTE）、iDEN和蜂窝数字分组数据（CDPD）。 
RIM202可提供在HEE204中，所述RIM202支持任何所要的频率，所述频率包括（但不限于）美国联邦通信委员会（US FCC）和加拿大工业频率（上行链路824MHz到849MHz和下行链路869MHz到894MHz）、US FCC和加拿大工业频率（上行链路1850MHz到1915MHz和下行链路1930MHz到1995MHz）、US FCC和加拿大工业频率（上行链路1710MHz到1755MHz和下行链路2110MHz到2155MHz）、US FCC频率（上行链路698MHz到716MHz和776MHz到787MHz和下行链路728MHz到746MHz）、EU R和TTE频率（上行链路880MHz到915MHz和下行链路925MHz到960MHz）、EU R和TTE频率（上行链路1710MHz到1785MHz和下行链路1805MHz到1880MHz）、EU R和TTE频率（上行链路1920MHz到1980MHz和下行链路2110MHz到2170MHz）、US FCC频率（上行链路806MHz到824MHz和下行链路851MHz到869MHz）、US FCC频率（上行链路896MHz到901MHz和下行链路929MHz到941MHz）、US FCC频率（上行链路793MHz到805MHz和下行链路763MHz到775MHz）和US FCC频率（上行链路和下行链路2495MHz到2690MHz）。 
在此实施方式中，将下行链路电气RF通信信号206D(1)-206D(R)提供到以光学接口模块（OIM）208(1)-208(N)的形式提供的多个光学接口，以将下行链路电气RF通信信号206D(1)-206D(R)转换为下行链路光学RF信号210D(1)-210D(R)。符号“1-N”指示可提供任何数目的参考组件1-N。如将在下文更详细地所描述，OIM208可配置为提供一或多个光学接口组件（OIC），所述OIC含有O/E转换器和E/O转换器。OIM208支持由RIM202提供的无线电频段，包括上文所描述的实例。因此，在此实施方式中，OIM208可支持例如从400MHz到2700MHz的无线电频段范围，因此不需要为较窄 无线电频段提供不同类型或模型的OIM208以支持用于HEE204中提供的支持不同无线电频段的RIM202的可能性。进一步地，例如，可针对例如400MHz到2700MHz频率范围内的子频段（例如400MHz到700MHz、700MHz到1GHz、1GHz到1.6GHz和1.6GHz到2.7GHz）最优化OIM208。 
各OIM208(1)-208(N)包括E/O转换器以将下行链路电气RF通信信号206D(1)-206D(R)转换为下行链路光学RF信号210D(1)-210D(R)。下行链路光学RF信号210D(1)-210D(R)通过一或多个下行链路光纤213D传送到多个RAU212(1)-212(P)。符号“1-P”指示可提供任何数目的参考组件1-P。在RAU212(1)-212(P)中提供的O/E转换器将下行链路光学RF信号210D(1)-210D(R)转换回下行链路电气RF通信信号206D(1)-206D(R)，所述下行链路电气RF通信信号206D(1)-206D(R)通过耦接到RAU212(1)-212(P)中的天线216(1)-216(P)的下行链路214(1)-214(P)提供到天线216(1)-216(P)的接收范围中的客户端装置。 
E/O转换器也提供在RAU212(1)-212(P)中以将通过天线216(1)-216(P)从客户端装置接收的上行链路电气RF通信信号206U(1)-206U(R)转换成将通过上行链路光纤213U传送到OIM208(1)-208(N)的上行链路光学RF信号210U(1)-210U(R)。OIM208(1)-208(N)包括O/E转换器，所述O/E转换器将上行链路光学信号210U(1)-210U(R)转换成上行链路电气RF通信信号220U(1)-220U(R)，所述上行链路电气RF通信信号220U(1)-220U(R)由RIM202(1)-202(M)处理并提供以作为上行链路电气RF通信信号220U(1)-220U(R)。也如图12中所示，例如，从由图4中的实例提供的DDS控制器和/或DDS交换机将通过下行链路电介质225D(1)-225D(P)传送的下行链路电气数字信号223D(1)-223D(P)以及通过上行链路电介质225U(1)-225U(P)传送的上行链路电气数字信号223U(1)-223U(P)独立于RF通信服务提供到RAU212(1)-212(P)。以通用元件符号在图12中图示图12与图4之间的通用元件。电力可提供在下行链路电介质225D(1)-225D(P)和/或上行链路电介质225U(1)-225U(P)中，并提供到RAU212(1)-212(P)。 
图12为向图11的分布式天线系统200中的RAU和/或其他远程通信单元提供数字数据服务和RF通信服务的示意图。图11和图12与所提供的其他图式之间的通用组件具有相同元件符号，且因此将不重新描述。如在图12中 所示，可提供电源模块（PSM）230以向RIM202(1)-222(M)和无线电分配卡（RDC）232提供电力，所述RDC232通过RDC234将来自RIM202(1)-202(M)的RF通信分配到OIM208(1)-208(N)。可提供PSM236以向OIM208(1)-208(N)提供电力。还可提供可包括网络和网络管理系统（NMC）接口的接口240以允许分布式天线系统200的配置和到RIM202(1)-202(M)和其他组件的通信。
