    Report 85 pages, 4 tables, 33 drawings, 14 sources. 
    Optical filament, issue system, optical  coupler,  lazer,  transmitter, 
principle scheme. 
    Object of study are ways of increasing reception capacity  of  channels 
fibre - optical issue systems by the way an issue of signals on one  optical 
filament in two directions. 
    Purpose of work -  a  determination  of  way  of  increasing  reception 
capacity of channels,  approach  for  using  on  connecting  lines  to  town 
telephone network. And development corresponding to a send device. 
    Choose type one -  a  fibre  optical  issue  system,  is  designed  its 
structured scheme, is designed principle a send device scheme. 
    In the process of work is form review of methods of issue of signals on 
one optical filament in two directions and is determined way  of  increasing 
reception capacity of channels, apropriate for using on connecting lines  to 
town telephone network.   |
