STTDFA-1920-BA-27-SM-B

*Note 1: The standard model is designed according to 1920~2020nm, and users can propose customized wavelengths according to their needs.

*Note 2: ACC mode - Automatic current control: the user sets the working current of the TDFA pump, and the TDFA automatically locks it to realize the constant pump current. When the input optical power fluctuates, the output power will also fluctuate accordingly, applicable to all TDFA models, PA amplifiers only support ACC mode.

APC mode - Automatic power control: the user sets the signal optical output power of TDFA, the PD automatic monitoring and feedback output power, TDFA control and adaptive adjustment pump to achieve the stability of the output signal, the power adjustment range in APC mode is usually 10%~100%. The advantage of APC mode is that when the input optical power fluctuates, the TDFA will reduce the output power fluctuation as much as possible. It is suitable for power type and line type TDFA, but not suitable for low repetition frequency pulse signals.
