soliton transmission in DWDM is possible or not?
why always anomalous dispersion region of optical fiber is used for soliton transmission system. Gaussian pulses also can transfer nearly equal distance compare to soliton(sech pulse) if i choosing the signal wavelength between 1550 to 1551nm (accumulated dispersion is +0.1 to +0.3 ps/nm/km) of DSF fiber . in previously reported papers soliton is reshaped by dispersion compensation using DCF ( as like SMF compensation)and attenuation is over come by EDFA amplification to transfer the soliton over the 10000 km. may i know what is the exact purpose of soliton. can i use the soliton for (32 or 64 channel) DWDM system.
