class="relatedlink">测试</a>仪<br /> <br /> 简介<br /> <br /> OMTDR-1000组合式时域反射计是一款结构紧凑、轻便的手<br /> <br /> 提式时域反射计，它集成了光时域反射计(OTDR)和金属时域反射<br /> <br /> 计(MTDR)，可用于光纤和金属线缆网络。<br /> <br /> OTDR模式可用来在安装和维护光通讯网络时，分析<br /> <br /> 光纤的特性。它可以提供光纤的完整信息，如光纤的衰<br /> <br /> 减、反射损耗、非反射损耗、定位光纤链路的故障点、<br /> <br /> 连接点和接合点等等。<br /> <br /> MTDR模式适用于如有线电视、CCTV、同轴电缆、动<br /> <br /> 力电缆、电话线和非屏蔽双绞线等至少有两根导线组成<br /> <br /> 的金属线缆的安装、维护和故障点定位（完全开路和短<br /> <br /> 路、部分开路和短路、加感线圈、连接松动和线路断开<br /> <br /> 等等）。<br /> <br /> OMTDR-1000组合式时域反射计为网络安装和维护人员<br /> <br /> 提供了完善的解决方法，它可用于任何施工现场混合网<br /> <br /> 尤其是LAN、CATV、HFC和FTTx网络）的测试、检修和保证。<br /> <br /> <a href="http://b.oecr.com/sell" target="_blank" class="relatedlink">产品</a>型号/规格<br /> <br /> 除了个别说明之除外，都以室内温度 20(C
