Abstract

Present article is devoted to study of a connection opportunity of erbium-doped fiber (amplifier EDFA), to the fiber-optic communication line (FOCL) by means of a unique fiber. As a result of it powerful pump radiation and information radiation are transferred in common on singlemode fiber. Such way of connection EDFA to FOCL is of interest at operation of a transfer line on explosive objects and etc., where entering electrical and electronic components into the certain zone is not supposed. The numerical ratings of nonlinear effects influence on an information signal are carried out for a case: an information at DWDM-signal in a range 1530 ... 1560 nm, pump on a wavelength 980 nm. As a making fiber was considered standard single mode fiber with a step structure of a refraction parameter change such as SF. Among nonlinear effects the following are considered: nonlinear attenuation and refraction, modulation instability, compelled_scatterion on acoustic waves and parametrical processes. Is shown, that the basic limiting factor on a pump is the self-focusing capacity, limiting at the end length of a supplying fiber in limits up to two kilometers. On such length the influence of nonlinear effects appears insignificant, that does not worsen appreciable quality of transfer.
