| 摘 要： | 波分复用(WDM:Wavelength Division Multiplexing)技术本质上是一种光波长分割复用或者光频率分割复用技术,具有设备成本低、网络的运营成本小、体积小、功耗低的特点,具有速率和协议透明性和很好的灵活性和可扩展性。把CWDM技术应用到TDM-PON中,可以实现PON的带宽升级,是目前经济技术条件下兼顾成本和效益的理想升级方法。

| Abstract: | Wavelength Division Multiplexing(WDM) is technology which multiplexs optical wavelength or optical frequency.The technology has some advantages including moderate equipment and network price,small volume and cheap power expense.Forthermore,the speed of transmission is flexible and its expanding is very good.The idea that CWDM is applied to TDMPON is proved to be a good proposal.The proposal can upgrade the bandwidth perfectly. |
