摘要
提出了一种新型的光码多分址(OCDMA)多用户分插复用器(ADM),所设计的ADM是基于阵列波导光栅(AWG)和二维时域/频域编码技术,可以从网络中同时取下多个码的数据而不影响剩余的码字信道,并且可以同时向网络中添加多个本地数据。设计的编解码器利用了Prime/OOC等具有特定规律的二维时域/频域扩展的码字,可以利用较少的AWG达到海量用户的编解码,系统集成度高。对所提出的ADM进行系统仿真,可以实现从4用户的网络中同时添加和取下2用户的功能,结果显示达到了所需的功能要求。
The proposed optical code-division multiple access （OCDMA） add-drop multiplexer （ADM） is based on arrayed waveguide gratings（AWG） and 2-D time-wavelength code. It drops several code channels simultaneously without disturbing the remaining code channels. The proposed ADM can also add several code channels simulataneously. Furthermore, with using the specific code, such as Prime/OOC,and a small number of AWGs,it is achieved to encode many users simultaneously to make the system compact. Simulation results show the proposed ADM possesses the required functions,according to the success of drop/add two from the 4-user network simultaneously.
