C-BAND DWDM EDFA

C-LIGHT C-BAND DWDM EDFA is a critical component in optical communication for long-haul, high-capacity transmission. Operating in the C-band (1530-1565 nm), it utilizes DWDM technology to densely multiplex multi-wavelength signals (typical channel spacing of 50/100 GHz) and amplifies them via erbium-doped fiber amplifiers (EDFA) with low noise and high gain, effectively compensating for fiber transmission loss. The C-band is preferred for DWDM systems due to its low attenuation and chromatic dispersion, while EDFA amplifies signals through stimulated emission of erbium ions, enabling ultra-long spans (e.g., submarine cables, backbone networks). This integrated solution significantly enhances fiber capacity and transmission distance, offering advantages such as broad bandwidth, high stability, and simultaneous multi-wavelength amplification, making it a core enabler of high-speed optical networks.
