The L band is the long‑wavelength band, covering 1565 nm – 1625 nm. Supported by mature EDFA technology, DWDM systems have expanded upward into the L band. In addition, erbium-doped fiber. At the heart of this technology lies the concept of wavelength division multiplexing (WDM), which allows multiple light signals, each at a different wavelength (or color), to travel simultaneously through a single optical fiber. This highlights how signal attenuation varies depending on the chosen wavelength. In these applications, its low attenuation enables it to transmit data over long distances. When 400G long-haul transmission uses 400G QPSK and 400G s16QAM modulation formats, to deliver the transmission capacity of 80 wavelengths, a larger channel spacing (at least 80 x 100 GHz) is required.
