摘要
讨论了FBGs编解码器的构造原理,设计并制作了基于实验室自行设计的二维OOC码字的二维FBGs编解码器,实现了双用户、数据速率为2.5Gb/s的非相干OCDMA系统。研究了当系统传输速率超过相邻FBG间距限制条件时,系统的编解码情况。
The structure principle of fiber Bragg grating encoder/decoder is discussed, the two-dimension optical othrogonal code designed in our laboratory is applied, and then the 2-D FBGs encoder/decoder based on the OOC is designed and fabricated. Two-user parallel transmission incoherent OCDMA system is achieved, the rate is up to 2.5Gb/s.The encoding and decoding of the system is studied when the transmission rate is beyond the critical value determined by the distance between fiber Bragg gratings.
