RM465 E1 19″英寸2U机架式16路阻抗匹配器75-120欧姆
RM465是19″2U高多功能机架式16路G.703平衡到非平衡转换器，它不仅能解决传统的16路双铜轴到双绞线之间的信号转换器，而且还可实现50-Pin(DB50/RJ48M)口到双同轴之间的信号转换。使用RM465用户只需使用普通120Ω双绞线或DB50线缆就能完成75Ω同轴硬件的信号通信。
 
性能特点： 
★ 符合ITU/CCITT G.703建议标准  
★ 完成BNC（75Ω）到RJ45（120Ω）双向信号转换
★ 完成BNC（75Ω）到DB50（120Ω）双向信号转换
★ 网络速率：2.048Mbps     
★ 链路到数据隔离电压1000V DC/AC
★ 75Ω接头：双同轴接口BNC，母头或公头
★ 120Ω接头：RJ-45、RJ48M（DB50）
★ 电源供电：无需外加电源或电池供电
★ 外形尺寸：48.3W × 8.9H × 10.2D (cm )

1.0 GENERAL INFORMATION
 
Thank you for your purchase of this Sakertele Electronics product, CY460 Series allow 75Ωcoax hardware to communicate with 120Ω twisted pair equipment. The CY460 Series specifically address the  ONP  requirement  that  European PTTsoffer 120 Ohm twisted pair terminations to their customers. The sign also output by them are scaled to match the pulse shape requirements specified by the CCITT G.703/E1 standard.
CY460 is a Dual Coax to RJ45 Balun Adapter which realize 75 Ohm coax to 120 Ohm RJ45 impedance converter.
