摘要：
Optical fiber-based distributed communications components and systems employing wavelength division multiplexing (WDM) for enhanced upgradability. The system comprises a plurality of downlink optical transmitters configured to receive downlink electrical radio frequency (RF) signals from a plurality of RF sources and convert the downlink electrical RF signals into downlink optical RF signals. The system also has a wavelength division multiplexer configured to multiplex downlink optical RF signals into a plurality of downlink wavelengths over a common downlink optical fiber connected to a plurality of remote antenna units (RAUs). In this manner, additional downlink optical fibers are not required to support providing additional RAUs in the system. Wavelength-division de-multiplexing can avoid providing additional uplink optical fibers to distribute uplink signals to RAUs added in the system.
摘要（中）：
基于光纤的分布式通信组件和采用波分复用（WDM）的系统，用于增强可升级性。 该系统包括多个下行链路光发射机，其被配置为从多个RF源接收下行链路电射频（RF）信号，并将下行链路电RF信号转换成下行链路光RF信号。 该系统还具有波分多路复用器，其被配置为通过连接到多个远程天线单元（RAU）的公共下行链路光纤将下行链路光RF信号复用为多个下行链路波长。 以这种方式，不需要额外的下行链路光纤来支持在系统中提供额外的RAU。 波分解除复用可以避免提供附加的上行光纤以将上行链路信号分配到在系统中添加的RAU。
