摘要

用计算机控制扫描法写入的低偏振模色散(PMD＜1.2ps)切趾啁啾光纤光栅级联补偿了4×10Gbps在G.652光纤上传输640km的色散

功率代价不大于1.5dB

光栅引入的损耗小于4dB

并研究了光源波动时系统功率代价的变化.实验表明总的功率代价不与光栅组的数目或光栅组数目的平方根成比例关系

为长距离无中继在G.652光纤传输用光栅补偿色散提供了实验依据

光栅的时延纹波不是各组单个光栅纹波的简单叠加

而是与光栅的位置及EDFA增益有关.

Abstract

The good quality cascaded multiwavelength chirped fiber Bragg grating (MFBG) were written using scanning mask/fiber technique.The MFBG had low PMD (1.2ps) and low insertion loss (4dB).Dispersion of 4×10Gbps WDM transmission over 640km of G.652 fiber was compensated using MFBG with all channels' power penalty less than 1.5dB.We had studied fluctuation of power penalty when source wavelength changed ±20GHz around ITU-T center.The fluctuation was less than 0.2dB.The experiment showed that overall penalty was proportional either to the number or to the square root of the number of the MFBG employed along the link.Ripple of overall MFBG delay and fluctuation of overall MFBG reflectivity were not simply piled up

but related with the place of MFBG and line amplifier gain.
