光耗损失预测方法

Prediction method of optical loss

基于多元回归以及统计损耗设计技术，提出一种可以用来设计新光纤网络和对已安装网络进行升级的一种光耗损失设计新方法．研究表明，通过使用1310nm和1550nm波长的光损耗值，基于预先决定的预测系数矩阵，该方法可以对O-L波段（1260-1625nm，除E波段外）进行高精度的光损耗设计和预测．研究还表明，通过追加恰当的预测用波长，可以提高该方法的精度．

A new method for optical loss design of newbuilt optical fiber networks and available ones to be updated was presented on the basis of multiple regression analysis and statistic loss design technique. The investigation result showed that, by using the optical loss values within the wavelength range from 1 310 nm to 1 550 nm and according to the predetermined prediction coefficient matrix, the method presented could be used for highprecision optical design and prediction for the O-L band （from 1 260 nm to 1 625 nm, excluding the E-band）. The further showed that its prediction accuracy could be improved if the wavelength for prediction was appropriately supplemented.
