OPTICAL AMPLIFIER

An optical amplifier may include an optical fiber to propagate a forward optical signal in a path of propagation of the optical amplifier. The optical fiber may have an input end face that is angled non-perpendicular to the path of propagation. The optical amplifier may include an optical component, in optical communication with the input end face of the optical fiber, to direct a backward optical emission away from the path of propagation. 一种光学放大器，可以包括光纤，其用于在光学放大器的传播路径中传播前向光信号。光纤可以具有与传播路径成非垂直角度的输入端面。光学放大器可以包括与光纤的输入端面光学通信的光学部件，用于引导反向光发射远离传播路径。
