Design and analyse of a communication system based on subcarrier multiplexing with multimode fiber
摘要
分析了多模光纤高频带通区域的传输特性,提出一种基于多载波复用的多模光纤通信系统。对该系统的传输特性进行了分析和仿真,结果表明:系统所用载波数是影响系统性能的重要因素;选取合适载波数,该系统可将10.2Gb/s的数据传输1km、将2.5Gb/s的数据传输4.2km;增大激光器的发送功率可以显著增加系统的传输距离。
The transmission performance of the multimode fiber frequency response in high frequency region has been analysed. A new communication system based on subcarrier multiplexing with multimode fiber has been proposed. The transmission performance of this system has been analysed and emulated. The emulation resuits say that the number of subcarriers used in the system gives a severity affection to the system performance; 10.2Gb/s signal can be transmitted over lkm and 2.5Gb/s signal over 4.2km in this system.The transmission distance can will be much larger by inceresing the power of the laser.
