Key features
Ø Adopting WDM module to realize long-distance transmission.
Ø Tx/Rx control and alarm messages can be transmitted via one fiber optic cable.
Ø Stable and improved signal transmission quality.
Ø One MU can support up to 4 RUs to maximize utilization of fiber optic cable (A star topology is supported between MU and RUs).
Ø USB/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.
主要特點
Ø 採用WDM模塊實現遠距離傳輸。
Ø Tx/Rx 控制和報警信息可以通過一根光纖傳輸。
Ø 穩定且提升的信號傳輸質量。
Ø 一個MU最多可支持4個RU,最大限度地利用光纜(MU與RU之間支持星型拓撲)。
Ø USB/RJ45端口提供連接筆記本電腦進行本地監管或基於IP的NMS(網絡管理系統),可以遠程監管中繼器的工作狀態,並通過以太網將運行參數下載到中繼器。
