A Bragg fiber design with potential for applications in metro networks is proposed for the first time. The average dispersion of the designed fiber is 10 ps/km.nm in the C-band, and in view of its estimated loss being very low, such a Bragg fiber should enable ultra low-loss DWDM transmission over 100 km at 10 Gbits/s. A Bragg fiber based metro network is an attractive proposition because it would not require any amplifier and dispersion compensator for distances approximately 100 km. This should significantly reduce installation and operational cost, and complexity of a metro network.
首次提出了一种有望应用于城域网的布拉格光纤设计。所设计光纤在C波段的平均色散为10 ps/km·nm，鉴于其估计损耗非常低，这种布拉格光纤应能实现10 Gbit/s速率下超过100 km的超低损耗密集波分复用传输。基于布拉格光纤的城域网是一个很有吸引力的方案，因为对于大约100 km的距离，它不需要任何放大器和色散补偿器。这将显著降低城域网的安装和运营成本以及复杂度。
