Abstract
Optical amplifiers and other optical network equipment is provided for use in fiber-optic communications networks. The equipment may include dynamic spectral filters and optical channel monitors. Temperature controllers may be used to control the temperatures of the dynamic spectral filters, optical channel monitors, and other components such as erbium-doped fiber coils in optical gain stages. Control units in the equipment may provide alarms based on status information and data from the dynamic spectral filters, optical channel monitors, temperature sensors, and other components.
