修订后的IEC 825-1（以及随后的CENELEC EN 60825-1）激光安全分类文件包含了对上一期的更改，尽管提高了最大允许发射LED强度，但仍然给自由空间光链路产品的分类带来了问题。与上一版本相比的变化主要与LED有关，允许比上一规范高出约50倍的输出光功率。我们表明，尽管变化，大多数现有的自由空间光链路不能被归类为1类。计算给出了1类分类，根据可及的曝光极限（AEL），最大允许源强度mW/Sr，在市场上的典型产品。
The amended IEC 825-1 (and consequently CENELEC EN 60825-1) laser safety classification document, incorporates changes from the previous issue which although improve the maximum allowed emitted LED intensity, it still poses problems to the classification of free space optical link products. The changes from the previous issue are mainly concerned with LEDs, allow approximately 50 times higher output optical power from the previous specification. We show that in spite of the changes, most of the existing free space optical links cannot be classified as class 1. Calculations are given for class 1 classification, based on accessible exposure limits (AEL), of maximum permissible source intensity in mW/Sr, for typical products available in the market.
