此类电光转换模块用于将高频电信号转换为光信号，电光转换模块通过光纤进行传输，在接收端再将光信号恢复成为电信号。
电光转换模块可无线电信号长距离传输的衰减及干扰等问题.
电光转换模块广泛用于无线通信信号，雷达信号， GPS信号等在特定场合或复杂环境下的传输。
modules convert RF signals to optical signals and back. One unit has an optical tranitter converts RF to Optical signal, and second receiver unit converts Optical to RF signal. The two units are connected by an optical fiber of the customer.
