Abstract

The invention relates to a multi-purpose rapid optimization and design device for EDFA parameters, a manufacture method thereof and an application method thereof. The device comprises an upper computer, a pump laser module, two optical isolators, a wavelength division multiplexer, a multi-path optical switch module and an Er-doped fiber combination module. The upper computer is connected with thewavelength division multiplexer and the multi-path optical switch module. The multi-path optical switch module is connected with the Er-doped fiber combination module. The wavelength division multiplexer is connected with the pump laser module and one optical isolator. Pump light generated by a pump laser and signals from the optical isolators are coupled to enter the multi-path optical switch module. An output end of the multi-path optical switch module is connected with the other optical isolator. The upper computer controls to selects different pumping power and Er-doped fibers and directlydetermines Er-doped fiber length and pumping power required by EDFA. Additionally, an online test is carried out.

Description

Technical field [0001] The invention belongs to the technical field of erbium-doped fiber amplifier design, and particularly relates to a multi-purpose EDFA parameter rapid optimization design device and a manufacturing and using method thereof. Background technique [0002] Erbium-doped fiber amplifier, EDFA for short, is an indispensable part in the fields of optical fiber sensing, optical communications, and lidar. The EDFA can be described by indicators such as small signal gain, saturation gain, noise figure, and gain flatness. Different application fields have different focus on EDFA index requirements. For example, when used in dense wavelength division multiplexing optical communication systems, high gain flatness is required; when used in power amplifiers for long-distance optical communications, large saturation gains are required; used in optical fiber sensing, especially detection When the signal is weak, the noise figure of the EDFA is lower. Even if the applicati...
