一种RFoG射频ONU
技术领域
本发明涉及光网络单元技术领域，更具体地说是一种RFoG射频ONU。
背景技术
目前，RFoG组网方案相对其他组网方案具有比较明显的优势!但是，RFoG射频广光网络单元也存在着明显的不足，RFoG技术是用回传信号的大小来区分数据信号还是噪声信号来控制回传激光器的开通和关断，从而实现“突发”模式。
根据网络设计需求，关断电平一般比开通电平要低10-30dB，这样才能保证基于光突发模式的上行信号传输更稳定。但这给产品的设计实现带来了困难，目前市场上绝大部分产品都做不到这一点。
发明内容
本发明的目的是为了弥补现有技术的不足，提供RFoG射频ONU。
本发明的目的是通过以下技术方案实现的：
一种RFoG射频ONU，包括光收发器，其特征在于：所述的光收发器连接有参考时钟收发模块，参考时钟收发模块连接有频率乘法器，频率乘法器连接有模数变换器，模数变换器连接有RF接收模块，参考时钟收发模块还连接有计时器，计时器连接有数据包装模块，数据包装模块同光收发器连接，频率乘法器还和计时器连接。
所述的一种RFoG射频ONU，其特征在于：所述的RFoG射频ONU通过光收发器同OLT连接。
本发明的优点在于：
