current variation conversion into the indicator frequency is weak at wounding length
of 100 m, while, if the current is more than 1000 A, passes through, we could clearly
register of variations of the OEO indicating frequency.
8.5.7 OEO Application in Lengthy Communication Links
of mm-Wave Range of 60–80 GHz with Large Speed
of the Information Transmission Up to 10 Gbit/s
The important application of OEO is in the lengthy radio communication channels
(including space communications) of mm-wave range (60–80 GHz) with high speed
of information transmission of 10 Gbit/s. Figure 8.25 shows experimental spectra of
