产品描述

比利时 Newtec MDM6000 高速卫星 IP 调制解调器是一款多功能的下一代调制解调器，针对蜂窝回程、IP 中继和光纤恢复等广泛的应用进行了优化。 MDM6000 调制解调器通常安装在点对点卫星链路的两端或星形网络的远程站点。 NEWTEC MDM6000 High Speed 与常规 MDM6000 相同，增加了一个外部数据包处理器，该处理器处理封装、解封装、整形和 QoS，以实现比常规 MDM6000 提供的更高的 pps 性能。单个调制解调器最多可以处理 800 kpps。该调制解调器完全符合 DVB-S2 和 DVBS2X 标准，在最大服务可用性的情况下实现最高效率。

核心效率

比利时 Newtec MDM6000 高速卫星调制解调器结合了许多创新元素，以提高当前市场可用的效率，从而降低总体总拥有成本。

DVB-S2X 标准中高达 256APSK 的新调制和前向纠错 (FEC) 代码与创新技术相结合，例如 133 MBaud、Clean Channel Technology®、带宽消除 (BWC)、自动上行链路功率控制 (AUPC)、FlexACM® 、QoS、Shaping 和 Equalink® 3 嵌入在调制解调器中，使卫星链路达到最高效率。

根据应用，Newtec MDM6000 高速卫星调制解调器可与 Newtec HUB6000 卫星集线器结合使用。通过添加 Newtec 的网络优化技术，例如加速、压缩和带宽管理，可以进一步提高性能。

最佳可用性

比利时 Newtec 的自适应技术 FlexACM 集成在 MDM6000 调制解调器中，可应对衰落条件（雨、灰尘、干扰）和倾斜轨道卫星。多亏了 FlexACM，衰落将不再中断集线器和远程站点之间的传输，也不会导致数据丢失。在任何时候都可以实现最大可能的吞吐量。此外，自动上行链路功率控制机制可确保始终最大限度地利用链路预算。
