Tx / Rx控制和警報消息可以通過一根光纜傳輸
l 將來自DCU的數字化蜂窩信號轉換為以太網格式,通過雙絞線電纜將數據和電源傳輸到RU
l 穩定並改善信號傳輸質量
l 一個MU最多可以支持4個DCU,以最大程度地利用光纜;一個DCU可以最多支持16RU,以減少MU的數量和PoE的功能
l RJ45端口提供到筆記本的鏈接,以進行本地監控或基於IP的NMS(網絡管理系統),從而可以遠程監控中繼器的工作狀態並通過以太網/ LAN將操作參數下載到中繼器
n Tx/Rx control and alarm messages can be transmitted via one fiber optic cable
n Digitalized cellular signals from DCU are converted to Ethernet format, Deliver data and power to RU via twisted pair cabling
n Stable and improved signal transmission quality
n One MU can support up to 4 DCUs to maximize utilization of fiber optic cable, One DCU can support Up to 16RUs to reduce the number of MU and PoE feature to RU
n RJ45 port provides a link to a notebook for local supervision or IP Based NMS (Network Management System) that can remotely supervise repeater’s working status and download operational parameters to the repeater via Ethernet/LAN
