EDFA Optical Amplifier Board

Product Details


       In optical communication network, fiber amplifier is an optical amplifier that amplifies optical signals directly in optical communication system.In communication systems using optical fibers, a technique for directly amplifying optical signals without converting them to electrical signals.

      Erbium-doped fiber is a fiber doped with a small amount of erbium (Er) ions in quartz fiber. It is the core of erbium-doped fiber amplifier.Since the late 1980s, the research of erbium-doped fiber amplifier has made great breakthroughs.WDM technology greatly increases the capacity of optical fiber communication.It has become the most widely used optical amplifiers in optical fiber communication。
