- FTTH是如何实现的?
光纤到户 (FTTH) 是一种宽带网络架构,利用光纤将高速互联网和其他通信服务直接传送到家庭。这涉及位于中心局的光线路终端 (OLT),它驱动光分配网络 (ODN),后者使用沿途的无源光分路器将信号路由到多个家庭。 那么光纤入户是如何安装的? 一 、预埋主干电缆 首先,施工队需要在小区附近挖一条沟,将馈线光缆与主干光缆接续起来。 二 . 引入电缆接入单 元 通过导线将馈线电缆从地面或管道中拉出,以进入您家外的地块或院子。 三. 电池分线盒分线 将馈线电缆放入小区内的分线盒,通过PLC进行分线,可供多户使用。 四. 光缆至用户接入点 将配线电缆放入家门口的储物箱中。 五、光缆入户 通过穿墙连接器或牵引线将引入电缆拉入房屋。 六. 室内布线 将白色或透明的电缆从客厅沿着家中的门框等一直拉到卧室。 七. 网络 最后一步,通过路由器将您的网络扩展到书房和卧室等房间。恭喜您完成 FTTH 构建! 热缩接头盒/套管/管(RSBJ、RSBA、XAGA、VASS、SVAM)光纤接头盒/盒ODF/配线架各种机柜完整的 FTTx 解决方案。 成都前宏 | QIANHONG COMMUNICATION 成都前宏通讯有限公司、成都前宏科技有限公司
- FTTA 关键组件和基础设施
光纤:FTTA 的核心组件是光纤本身。单模光纤通常用于 FTTA 部署,因为它们能够以最小的衰减长距离传输光信号。这些光纤旨在将高速数据、语音和视频信号从基站传输到天线。例如,在大规模 5G 网络部署中,铺设了数公里的单模光纤以将多个 RRH 连接到各自的 BBU。 光收发器:光收发器对于将电信号转换为光信号以及将光信号转换为电信号至关重要。BBU 端的发射器将电信号转换为适合通过光纤传输的光信号。RRH 端的接收器执行相反的操作,将接收到的光信号转换回电信号。高性能光收发器对于保持信号完整性和确保快速的数据传输速率至关重要。 远程无线电头 (RRH):RRH 位于天线附近,负责放大从光纤接收到的电信号并以无线方式传输。它还执行信号调制和解调等功能。RRH 设计紧凑且节能,可轻松安装在各种天线站点。 基带单元 (BBU):BBU 是基站的中央处理单元。它们负责数字信号处理任务,例如编码、解码和管理与核心网络的通信。在基于 FTTA 的网络中,BBU 通过光纤连接到多个 RRH,从而实现无线网络的集中控制和管理。 基础设施安装:FTTA 基础设施的安装需要仔细规划。光纤电缆需要铺设在地下或架空位置,具体取决于地形和当地法规。在城市地区,通常首选地下光纤安装,以避免干扰并保持城市景观的美观。此外,需要对光纤电缆进行适当的保护,以防止环境因素、施工活动或其他潜在危险造成的损坏。 FTTA 基础设施还需要与现有的无线网络基础设施进行集成,包括核心网络、电源系统和其他支持设备。这种集成需要兼容性测试和无缝协调,以确保整个无线通信网络的顺利运行。热缩接头盒/套管/管 (RSBJ、RSBA、XAGA、VASS、SVAM)光纤接头盒/盒ODF/配线架各种机柜FTTx 完整解决方案 网址://www.qhtele.com.cn oversea@zcloudtech.net 成都前宏通讯有限公司 成都前宏科技有限公司
