型号458-3SL
用途线路模拟器
兼容DLS6700
Telebyte's 458 line modules simulate several cable types and offer the bandwidth requirements for today's xDSL technologies such as varieties of G.SHDSL, ADSL, ADSL2+ and VDSL2. Line lengths and configuration settings appear on an LCD display on the front of the unit and can be set via a keypad. We also offer other modules that work with our 458-CC-16/458-CM including the 458-SM-2-16 Transparent Switching Module.

Impedance: ± 10% (20KHz - 30MHz)
Control Remote control: via RS-232
Connections Shielded: RJ-45 jacks to minimize crosstalk
模拟的广域网环境，可以很容易地对网络带宽、延迟、数据丢失、拥塞情况以及其他一些网络损伤状态进行模拟，在实验室条件下实现对应用程序或网络设备在各种网络条件下的性能的测试。
网络损伤测试仪的使用可以大地降低网络管理员故障排查网络故障的时间，可以提供综合施工人员的工作效率。还可以加速工程项目的进度和工程质量。
