Abstract

The invention provides a device for automatically testing the performance of an erbium doped fiber amplifier (EDFA). Special software is adopted to automatically control and operate the detection device so as to realize the automatic tests of the gain flatness, transient response and signal-to-noise ratio of the EDFA. Manual intervention is not needed in the whole test process. The automatic test device of the EDFA can largely reduce device setting time, optical path switching time and the test recording and analysis time which are consumed by manual operation, and can further avoid human error caused by manually recording test data. The automatic test mode of the device causes the operation of EDFA performance test to be simple, fast and reliable, which greatly improves the efficiency of the EDFA performance test, and can fully meet the application requirement of enterprises for mass EDFA tests.

Description

technical field [0001] The invention relates to a device capable of automatically testing the performance of an erbium-doped fiber amplifier (EDFA), in particular to an automatic test device for EDFA gain flatness, transient response and signal-to-noise ratio. Background technique [0002] In the 21st century, optical cable networks have spread all over the world, and optical fiber communication has become an important pillar of the "information superhighway". However, due to the transmission loss of the optical fiber itself, the optical signal can only be transmitted not too far away, and it will attenuate to the extent that the receiver cannot distinguish. The advent of erbium-doped fiber amplifier (EDFA) has caused a revolution in optical communication technology. Due to its advantages of high gain, high output power, low noise, wide bandwidth, and polarization-independent, EDFA is used in many fields and occasions. It is gradually replacing the traditional optical-elect...
