L-Band Erbium-Doped Fiber Optimization and Transmission Investigation

Photonics
The optical spectrum resource in the C-band has been used up due to dense wavelength division multiplexing (DWDM). Because of devices’ compatibility with both the C-band and the L-band, the L-band is a good choice for further capacity expansion ...
