CDM-625

Advanced Satellite Modem_高阶卫星数据机

这是Comtech的第一款高阶卫星数据机,它将诸如VersaFECFE和低密度奇偶校验(LDPC)码之类的高级前向纠错(FEC)与革命性的DoubleTalk Carrier-in-Carrier频宽堆叠,从而在所有情况下均实现了最大程度的节省。 先进技术的这种结合实现了多维优化,从而使卫星通信用户能够:
•最大限度地减少运营费用(OPEX)
•在不使用额外转发器资源的情况下最大化吞吐量
•在不使用额外转发器资源的情况下最大化可用性(边际)
•通过允许使用较小的BUC / HPA和/或天线来最小化资本支出(CAPEX)
•或者,组合以满足特定的业务需求
