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 an37dBm 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 the ‘PowerSet’ area and enter the desired power value on the pop-up keyboard.
Press Enter to apply the settings. You can also adjust the power using the up and down arrows on the right. In ACC mode, you can set the pump current value.
Connecting the RS232 data cable allows for parameter settings via software.
The red ‘STOP’ button on the right is an emergency stop switch. If you need to stop the amplifier immediately during use, press the ‘STOP’ button. After troubleshooting, rotate the ‘STOP’ button clockwise to reset it and then restart the amplifier.
It is important to note that when the amplifier is in the light output state (with the activation switch on), it is strictly forbidden to plug, unplug, or connect the fiber optic patch cord connector. Otherwise, it is very easy to damage the end face of the fiber optic patch cord connector and the amplifier itself, which may lead to failure.
