Gain Flattened Erbium-doped Fiber Amplifier for C++-band

DK Photonics Gain Flattened Erbium-doped Fiber Amplifier for C++ band is a fiber amplifier product specifically designed for fiber communication systems. It can simultaneously amplify multiple wavelength signals within the C++band, covering the wavelength range of 1524-1572nm (frequency 190.65~196.675THz), while maintaining consistent gain between wavelengths with a gain flatness of ≤ 1.5 dB. It has the advantages of ultra wide spectrum, high gain, low noise, and flat gain.

Features

  • High output power
  • High Gain
  • Wide wavelength range

Applications

  • Fiber Communications
  • Fiber Laser
  • Fiber Sensors

*Note 1:

  • ACC mode: Automatic current control: the EDFA pump working current is set by the user and automatically locked by the EDFA to achieve a constant pump current. When the input optical power fluctuates, the output power will also fluctuate accordingly, which is applicable to all EDFA models.
  • APC mode: Automatic power control mode, where the user sets the signal light output power of the EDFA. Based on the output power monitored by the PD, the EDFA automatically controls and adjusts the pump current to achieve stable output signal. In APC mode, the user can adjust the output power within a range of 10% to 100% of the maximum output power. The advantage of APC mode is that when the input optical power fluctuates, EDFA will minimize the fluctuation of output power as much as possible
  • AGC mode: Automatic gain control mode, in which the user sets the gain coefficient of EDFA. EDFA will automatically control and adjust the pump current based on the input and output power detected by PD to achieve the most stable gain multiple. When the input optical power fluctuates, the output power will also fluctuate accordingly, but the gain coefficient is generally stable.
