Abstract

本申请实施例提供了一种确定光信号功率变化的方法及功率计算装置。本申请实施例方法包括如下步骤。获取包括多个波长信号的第一光信号，多个波长信号分布在多个波带，不同得波带对应不同的波长信号，每个波带包括至少一个波长信号的波长值。之后，检测每个波带的光功率以及每个波带的中心波长信号，并获取预设单波传输功率以及预设系数。接下来，根据每个波带的光功率以及预设单波传输功率确定等效波长信号的等效数量N，并根据每个波带的光功率以及每个波带的中心波长信号确定第一光信号对应的等效波长信号。进而，根据预设系数、等效波长信号、等效数量以及预设单波传输功率确定用于补偿第一光信号在光纤中传输的第一功率变化值的目标功率。
