T1 ON A METHOD FOR INCREASING THE PERFORMANCE EFFICIENCY OF OPTICAL SIGNAL TRANSMISSION SYSTEMS JF Telecommunications and Radio Engineering JO TRE YR 2013 FD 2013-03-25 VO 72 IS 4 SP 353 OP 359 K1 fiber-optic communication lines K1 sensitivity of the optoelectronic communication channel K1 optical subscriber terminal K1 information efficiency K1 optical signals, mean bit error probability of optical signal reception AB The topology of a ring structure of fiber-optic communication lines, formed by optical subscriber terminals based on spectral and dense spectral multiplexing with frequency demultiplexing of communication channels, is investigated. Some performance characteristics of the optical signal transmission systems are defined.
