Optical modulation ndi kuwonjezera chidziwitso kwa chonyamulira kuwala mafunde, kotero kuti chizindikiro cha chonyamulira kuwala mafunde kusintha ndi kusintha kwa chizindikiro kunja, kuphatikizapo mphamvu ya mafunde kuwala, gawo, pafupipafupi, polarization, wavelength ndi zina zotero.Kuwala kosinthika komwe kumanyamula chidziwitsocho kumapatsirana mu ulusi, kuzindikiridwa ndi chojambulira zithunzi, kenako ndikutsitsa zomwe zikufunika.
Maziko akuthupi a electro-optic modulation ndi electro-optic effect, ndiko kuti, pansi pa mphamvu ya magetsi ogwiritsidwa ntchito, chiwerengero cha refractive cha makristasi ena chidzasintha, ndipo pamene mafunde a kuwala akudutsa mu sing'anga iyi, mawonekedwe ake opatsirana adzasintha. kukhudzidwa ndi kusinthidwa.
Pali mitundu yambiri ya ma electro-optic modulators(EO modulator), omwe amatha kugawidwa m'magulu osiyanasiyana malinga ndi miyezo yosiyanasiyana.
Malinga ndi ma elekitirodi osiyanasiyana, EOM ikhoza kugawidwa kukhala lumped parameter modulator ndi modulator yoyendayenda.
Malinga ndi mawonekedwe osiyanasiyana a waveguide, EOIM ikhoza kugawidwa kukhala Msch-Zehnder interference intensity modulator ndi directional coupling intensity modulator.
Malinga ndi ubale pakati pa mayendedwe a kuwala ndi momwe magetsi amayendera, EOM imatha kugawidwa kukhala ma modulators aatali ndi ma modulator odutsa.The longitudinal electro-optic modulator ali ndi ubwino wa dongosolo losavuta, ntchito khola (odziimira polarization), palibe birefringence zachilengedwe, etc. kuipa kwake ndi chakuti theka-wave voteji ndi okwera kwambiri, makamaka pamene kusinthasintha kusinthasintha ndi mkulu, mphamvu. kutayika kuli kwakukulu.
Electro-optical intensity modulator ndi chinthu chophatikizika kwambiri cha Rofea chokhala ndi ufulu wodziyimira pawokha waluso.Chidachi chimagwirizanitsa ma electro-optical intensity modulator, microwave amplifier ndi dera lake loyendetsa galimoto kukhala imodzi, zomwe sizimangothandiza kugwiritsa ntchito ogwiritsa ntchito, komanso zimathandizira kwambiri kudalirika kwa MZ intensity modulator, ndipo ikhoza kupereka ntchito zosinthidwa malinga ndi zosowa za wogwiritsa ntchito.
Mbali:
⚫ Kutayika kochepa kolowetsa
⚫ bandwidth yogwira ntchito kwambiri
⚫ Kupindula kosinthika ndi malo ogwirira ntchito
⚫ AC 220V
⚫ Yosavuta kugwiritsa ntchito, gwero loyatsira losankha
Ntchito:
⚫Njira yothamanga kwambiri yosinthira kunja
⚫ Dongosolo lophunzitsira ndi zoyeserera
⚫ jenereta yamagetsi yamagetsi
⚫Optical RZ, NRZ system
