There is presenting results successful optical transmission based on the SCM technique. Spectrally effective 64-QAM modulation has been used. Frequency range of the carrier used at the experiment had been changed in a range of 1 to 1.5 GHz, what is well beyond the baseband of used at the experiment MM fiber.
The paper presents realization of 4 channel incoherent MIMO system operating over 4.4 km of 50 μm core silica GI MM fiber. At the transmitter side, there were generated four uncorrelated pseudorandom binary sequences (PRBS) of lengths 2^7-1 that modeled short length line codes. These binary signals independently drove four QPSK modulators and 4 transmitter lasers. RML launches with different offsets...
Frequency response of Multimode (MM) fibers beyond the baseband is studied both theoretically and experimentally. It is shown that in the absence of mode group mixing there are relative flat passbands suitable for transmission in such fibers if the number of mode groups propagating is not too large. Such conditions are usually met for typical contemporary graded index (GI) silica fibers. It is also...
