 In the vast field of optical communication, L-band erbium-doped fiber amplifiers are playing an increasingly crucial role. The L-band, following the C-band, is a valuable spectrum resource that has been extensively explored in dense wavelength division multiplexing (DWDM) systems. The L-band erbium-doped fiber amplifier, based on erbium-doped fiber amplifier (EDFA) technology, is a core device specifically designed for efficient amplification of signals in this band, providing powerful support for long-distance, high-capacity optical communication systems. This is an L-band erbium-doped fiber amplifier.  This product uses an LCD touchscreen for control and display of operating parameters. We can see the amplifier's current input and output power, Pump Current (C1/C2), and pump laser temperature (T1/T2) on the screen. We can set the operating mode and adjust parameters on the screen. Click the Mode area to select the operating mode. In APC mode, we can set the power. Click th...
