Control polarization the precise way
Polarization-dependent effects often have undesirable effects in fiber-optic systems, such as polarization-dependent losses (PDL) in components and devices or the amplifier’s polarization dependence in EDFAs. You can control the polarization in two ways:
- With “scrambling”, the polarization state of the light with high frequency changes. In other words, the light is more or less depolarized
- Use polarization controllers if you would like a specific, fixed polarization state
