Method of the optical signal amplifying with distance pump and experience of it realization

摘要

The article is devoted to experimental study of a connection possibility of the EDFA amplifier to the fiber-optical communication line in conditions of joint transfer of a pump radiation and information DWDM-signal on single-mode fiber segment of certain length. The technique of realization of experiment is developed, the research experimental installation is assembled. The range of lengths researched oдHOMOдOBoгo of single-mode segment (accordingly, range of allowable potencies of a pump source) is revealed, where the transfer quality of the communication line at a level transfers of a voice PE < 10~(-6) and data transfer PE < 10~(-9) is ensured. The researches for a monochromatic information radiation (λ = 1550 nm) and WDM-signal (λ = 1550 nm and λ = 1310 nm) are conducted. The variant of use of the developed method of length regenerate plot magnification of a network on a really maintained fiber-optical network Open Joint Stock Company Bashkir-Energo and Open Joint Petroleum Company Bashneft is considered.
