    Erbium-Doped Fiber Amplifiers (EDFAs)

    Erbium-doped fiber amplifiers (EDFAs) make use of rare-earth elements such as erbium (Er3+) as amplification medium. It is doped into the fiber core during the manufacturing process. It consists of a short piece of fiber (typically 10 m or so) made of glass in which a small controlled amount of e...

    Waveband for optical fiber

    Optical fiber communication takes light as an information carrier to communicate. It can be transmitted through fiber core. However, not every beam of light is suitable for communication. Transmission loss varies with different waveband of light.  For achieving the less loss and being efficiently...
