EDFA equalization technology - GFF introduction

EDFA is the core functional device in the optical transmission system, which has the advantages of high gain, large bandwidth, low noise, gain characteristics insensitive to optical polarization state, transparent to data rate and format, and negligible channel crosstalk in multi-channel systems. . The combination of DWDM and EDFA can not only increase the capacity of the system, but also has high flexibility and economy. However, due to the dense multiplexing of channel wavelengths and the uniform broadening characteristics of EDFA, there is fierce competition between different channels, and the gain and spectral line shape of EDFA need to be kept stable, so the problem of EDFA gain control and flatness is introduced. At present, there are mainly technical means to achieve EDFA gain flatness, such as thin-film filtering, low-light sinusoidal filtering, and fiber grating filtering. Optical gain flattening filter GFF is based on mature thin-film filtering technology, which is used in EDFA to compensate the uneven gain amplification under different DWDM channels. Figure 1 shows the working principle of the GFF diaphragm.

Introduction to Coarse Wavelength Division Multiplexer Application

In principle, it is to use an optical multiplexer to multiplex optical signals of different wavelengths into a single optical fiber for transmission, and at the receiving end of the link, use an optical demultiplexer to decompose the mixed signals in the optical fiber into signals of different wavelengths , connect to the corresponding receiving device.

Affecting the performance index of WDM wavelength division multiplexer

The working band of WDM devices, such as 1550 wavelength, distinguishes three bands: S-band (short-wavelength band 1460-1528nm), C-band (conventional band 1530-1565nm), L-band (long-wavelength band 1565-1625nm).
