OPTICAL MODULE AND ERBIUM-DOPED FIBER AMPLIFIER

摘要

An optical module includes an optical fiber component, a wavelength division multiplexing (WDM) filter, at least one isolator, a mirror and an optical detecting component. The optical fiber component, the WDM filter, the at least one isolator, the mirror and the optical detecting component are configured to prevent a signal light which is before an EDF component and an amplified signal light after the EDF component from counter transmission with a simplified structure and compact size.
