Title: Optical amplifying and repeating system
Inventor: MITO TOSHIHIRO
IPC: H04B10/291
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To enable long repetition interval transmission, while decreasing the number of repeaters by alternately arranging repeaters and remote excited branching devices on an optical transmission line and amplifying light through an Er added fiber corresponding to excited light. SOLUTION: A data signal from a landing station 10a is applied to optical synthesizers/branching filters 5a and 5b of a repeater 1. In this case, the data signal is respectively synthesized with the excited light from exciting light sources 4a and 4b, amplified by optical amplifiers 3a and 3b and later inputted to a remote excited branching device 8. The remote excited branching device 8 amplifies the synthesized light through Er added fibers 6a and 6b corresponding to the excited light. Next, the synthesized light is branched by optical synthesizers/branching filters 51 and 52 of repeaters 1a and 1b, and only the optical data signal is applied to optical amplifiers 31 and 32 respectively. In this case, the amplified optical data signal is respectively transmitted to landing stations 10b and 10c. Thus, since light is amplified by alternately arranging the repeaters and the remote excited branching devices on the optical transmission line, the number of repeaters can be decreased.
