Optimization of Apodized Chirped Fiber BraggGrating for Dispersion Compensation

Multiwavelength chirped fiber Bragg grating (MCFBG) is a more valuable approach to chromatic dispersion compensation. And adjusting the structure of FBG will optimize the performance of dispersion compensator in 8×10 Gb/s DWDM network, which is proved by simulating calculation.

8×10 Gb/s 103 km DWDM色散补偿的实验

研制了啁啾的多波长光纤 Bragg光栅 ,波长、波长间隔符合 ITU- T标准 ,利用该光栅可以同时对多信道波长进行色散补偿 ,光栅的每个波长补偿范围满足 ITU- T对应信道波长波动的要求 ;该光栅能滤除反射峰之间未用波长范围内的放大器的自发辐射噪声 (ASE)。进行了 8× 10 Gb/ s 10 3 km WDM色散补偿实验 。
