射频光纤模块
Description
射频光纤模块用于将射频信号转为光信号，通过光纤传输，接收端再将光信号转换成射频信号，其距离长、带宽高、响应平坦，使用于通信及雷达系统。卫星通信中，点到点的天线可以通过此设备将射频信号转为光信号，通过光纤连接至几米到几千米的控制室外。广播信号也可以将RF信号转为光信号通过光纤传输。雷达系统可以通过此方式将雷达天线和信号室进行远距离连接。射频光纤模块根据带宽的不同，有8GHz,15GHz,20GHz不同射频带宽的产品，另有3GHz, 2.4GHz, 1.5GHz等低频段，根据需要，可选择单向和双向传输系统。
The RF over fiber transmission module FT-AH-ROF120M designed for RF/wireless signal transmission over long distance, which overcome the problem of high loss when the RF/wireless signal transmit over coaxial cable or free space.
