Abstract
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.
