Tags: ER3-N Amplifier, optical fiber, amplifier
Some signals will be attenuated and lost in cases where the distance of information transmission is long (more than one kilometer) or where pure materials (glass) are not used to manufacture optical fibers. In such cases, in order to amplify the attenuated optical signals, one or more "optical amplifiers" are used. An optical amplifier is composed of multiple optical fibers along with a specific doping coating. The Optical Fiber Amplifier ER3-N functions like a switch and operates based on a magnetic sensor.
