摘要
提出了一种基于波长间插复用的载波抑制双边带(ODSB-SC)射频光纤传输(ROF)系统,该系统采用马赫曾德尔调制器(MZM)实现了ODSB-CS调制信号,采用马赫曾德尔干涉仪(MZI)实现了两路RF信号的解复用,并采用光子模拟软件设计出了一个15GHz和25GHz的两路射频(RF)信号经过波长间插复用的ODSB-SC的ROF系统,讨论了MZI的延时时间对解复用出来的RF复用信号性能的影响。
Proposes a wavelength interleaving based on double sideband suppression（ ODSB- SC） radio frequency（ ROF） optical fiber transmission system,which using Mach- Zehnder modulator（ MZM） to realize the ODSB- CS modulation signal,the Mach- Zehnder interferometer（ MZI） was used to realize the two RF signal de multiplexing,and the theoretical analysis of their working principle. Using simulation software design out a 15 GHz and 25 ghz two radio frequency（ RF） signal through the wavelength in ROF system multiplexing ODSB- SC,gives the RF signal multiplexing and solution before and after the multiplexing spectrum,Q value of eye and,discuss the MZI delay time to solve the influence of the performance of RF multiplexed signal,obtained the optimal delay time for the conclusion of 0. 34 ns.
