edfa module optical fiber tester Erbium-doped fiber amplifier

EDFA, short for Erbium-doped Optical Fiber Amplifer, is an active optical device for amplifying signal light. The birth of the bait-doped fiber amplifier is a revolutionary breakthrough in the field of optical fiber communication. It makes long-distance, large-capacity and high-rate optical fiber communication possible. It is an indispensable component in DWDM system and future high-speed systems and all-optical networks. Its research and application is of great significance to the development of optical fiber communication. In China, EDFA series products developed by Wuhan Academy of Postal Sciences are the only domestic commercial products at present, and have been widely used in engineering.
