基于混合调制的WDM-PON及信号广播的研究
|
摘要
相对于EPON和GPON,WDM-PON的构架简单,不需要EPON/GPON的突发模式发送和接收以及动态带宽分配、测距和时延精确控制等复杂技术。WDM-PON由于能够提供巨大的带宽,具有独立的比特率、协议透明、平滑升级、可靠的QoS以及出色的安全性和保密性等特点,已经吸引了越来越多的学者和运营商的注意和研究。随着光电器件成本的不断降低,WDM-PON必然在下一代的光接入网中占据重要的地位。
本文主要在介绍WDM-PON的关键技术的基础上,对WDM-PON的系统实现及网络结构组成等方面进行分析与研究,主要内容包括:
1、首先提出了一种基于相位、偏振混合调制的OFSK发射机,并将这种光发射机应用到下行2.5Gb/s OFSK调制、上行2.5Gb/s ASK调制的WDM-PON系统中,不但结构简单,而且调制速率仅仅受限于外调制器;在没有色散补偿的情况下,双向传输的功率代价均较小;这种新型调制格式不仅可以维持恒定的光强,支持正交调制,而且受光纤的非线性效应的影响较小。
2、然后针对WDM-PON中存在的光源技术问题,提出一种基于波长注入锁定FP-LD的低成本光源解决方案,搭建实验系统;并参与开发基于波长锁定技术的光发射机,提出光发射机的温控和光控方案。
3、最后提出了一种在WDM-PON中传输模拟或数字有线电视(CATV)信号的廉价高效方法,仿真CATV信号在WDM-PON中下行传输的性能,理论分析和数值仿真表明,在满足传输电视信号传输带宽750 MHz的前提下,信噪比在43 dB以上,满足光纤到户传输要求。实验结果表明,加入EDFA可以有效抑制相对强度噪声,使信噪比提高3～4 dB。然后设计了一种实验方案在WDM-PON中同时传输单播信号和广播信号,将ASK-DPSK的混合调制方式应用到WDM-PON的下行传输中,仅仅需要一些简单的调制器和解调装置便可以使光谱效率加倍,很好地实现了信号广播的可选择性。
Compared to EPON and GPON, WDM-PON has a simple framework and does not consist of the following series of sophisticated techniques such as burst-mode transmitter and receiver, as well as dynamic bandwidth allocation, ranging and precise control of latency. While WDM-PON can provide significant bandwidth, bit transparency, smooth upgradation, reliable QoS, as well as excellent security and confidentiality etc., it has attracted more and more attention of scholars and communication operators. With the reduction of price of optoelectronic devices, WDM-PON will necessarily play an important role in the next generation of optical access network.
This thesis mainly discussed the issues regarding implementation of the WDM-PON system and formation of its network structure after the introduction of the WDM-PON key techniques. The thesis can be outlined as follows:
1、Firstly, we propose a novel OFSK transmitter based on phase/polarization combined modulation format, and apply the above OFSK transmitter into WDM-PON with 2.5Gb/s downstream OFSK signals and 2.5Gb/s upstream ASK signals to make it much simpler and operate at the data rate only limited by the external modulator. It shows that demodulated OFSK signals embody smaller power penalty for both the downstream case and upstream case without any dispersion compensation. Moreover, the above modulation format can keep the intensity of optical carrier constant, and it can be combined with orthogonal modulations, and also be little affected by the nonlinear effects of fiber.
2、Secondly, to solve the light source technical problems in the presence of WDM-PON, we propose a low-lost light source solution based on wavelength injection-locked FP-LD and set up one experimental system; Participate in the development of an optical transmitter based on wavelength injection-locked technology and propose temperature and light control solutions for the optical transmitter.
3、Lastly, a cost-effective approach for analog or digital Cable Television (CATV) signal transmission over a Wavelength Division Multiplexing Passive Optical Network (WDM-PON) is proposed and downstream transmission performance for CATV signal is simulated. The numerical analysis shows that SNR can reach above 43dB at the bandwidth of 750MHZ, thus meets the need of CATV transmission over fiber to the home. From the experiment result, it is seen that EDFA can effectively suppress the relatively intensity noise, improving SNR by 3～4dB. Then an experimental scheme is designed to simultaneously transmit unicast and broadcast signals. It justs need some simple modulator and demodulator devices when we apply the ASK-DPSK combined modulation format to the downstream transmission of WDM-PON. It can not only double the spectral efficiency, and also achieve the selectivity of signal broadcasting.
