Abstract

The key of analyzing the light signal transmitting in fiber is the interaction and correlation between them. At present, we must consider the medium and the light field as one united system. Its strict physical theory is the quantum electrodynamics (QED), to process the light field and medium to second quantization. The quantum theory is considering both the medium and the light field as quantum wave function, so we can discuss the extreme limit frequency and distance. In the analyzing of extreme limit frequency, we can get it by considering two situations: the first is the photoelectric effect between light signal and fiber medium, the second is the transmission effect of high frequency incident light. In the analyzing of extreme limit of light signal distance, we will consider the interaction of the electron and the light field. We apply the theory and formula of scattering section. We analyze the colliding mechanism of particles in medium. We calculate the transmitting situation of photon energy according the energy and momentum reservation laws. According to the maximum frequency shift of light which is allowed by optical receiver, we can get the extreme limit distance of signal transmitting.
