摘要

在5G通信网络中使用密集波分复用光纤无线电(DWDM-RoF)技术有各种好处,包括增加容量和数据速率,以及降低运营成本。这就是为什么许多研究人员开始开发系统和方法来实现最佳收入。本文设计了一种32通道DWDM RoF系统,采用混合补偿技术实现了1.28 Tbps的高效传输。系统性能调查包括三种频率间隔(100,150,200)GHz的情况。此外,研究了不同的调制格式,以处理未来使用的最可靠的方法。对系统的质量因子(QF)和误码率(BER)参数进行了分析,并与原有系统进行了比较。结果表明,采用对称混合补偿对提高系统的参数结果有显著的影响。其中,当使用非归零(NRZ)时,在(60、120、180和240)km的距离上,获得的平均QF参数值分别为(20.89、15.60、12.69、10.46)dBm。与此同时,同一研究距离子集的误码率分别为2.43*10−80、2.85*10−29、1.09 *10−18、7.61*10−11。同时,用RZ调制方法处理所提出的系统时,数值进一步提高。

Implementation of Symmetrical Compensation based DWDM RoF system Toward Tbps of data transmission for 5G Fiber Optic Networks
There are various benefits to using a Dense Wavelength Division Multiplexing Radio over Fiber (DWDM-RoF) technology in 5G communication networks, including increased capacity and data rate, as well as a reduction in the cost of operation. This is why many researchers start developing systems and approaches to achieve the best income. In this paper, it has been designed a 32-channel DWDM RoF system to handle efficient 1.28 Tbps data rate transmission by using a hybrid approach of compensation techniques. Three cases of frequency spacing (100,150,200) GHz were included in the system performance investigation. Additionally, different modulation formats are studied to handle the most reliable method to be utilized in the future. Results are obtained concerning Quality Factor (QF) and Bit Error Rate (BER) parameters are analyzed, and compared with the previous system. Such results indicate a significant impact of using the symmetrical hybrid compensation in boosting the parameters result for the proposed system. Where when using The NonReturn to Zero (NRZ) the achieved averaged QF parameter values were (20.89, 15.60, 12.69, 10.46) dBm for the distances of (60, 120, 180, and 240) km respectively. Meanwhile, the BER values were (2.43*10−80, 2.85*10−29, 1.09 *10−18, 7.61*10−11) for the same subset of studied distances respectively. Meanwhile, when handling the proposed system with the RZ modulation method the values are further improved.
