摘要

Calibration procedure in the field of distributed Raman amplifiers contrapropagantes for operation in the mode of automatic gain control.The new process or calibration method used in the telecommunications engineering specifically in fiber optic communications, optical devices distributed Raman amplifiers contrapropagantes carried out in the field with the purpose to optimize the operation of the device. The optical mode to automatic gain control.Based on the evaluation of the efficiency of pumping lasers in the amplification with the fiber present in the field, and in the correction of the powers of pump during operation of the amplifier according to this evaluation.Which consists in adapting the gain control of the Dr fiber transmission in field without prior knowledge of their characteristics, based on the adjustment of pumping powers pru00e9determinadas in the laboratory, without addition of any component or additional device.
