Zindikirani:
1 * imatanthawuza kuyika kwamtundu wamagetsi ku module pomwe kutulutsa kwa modulator ndikokwanira. Pakuti otsika mfundo ulamuliro modulitsa ndi mkulu kutha chiŵerengero, mphamvu athandizira ayenera moyenerera kuchuluka; Ndi zofunikira zapadera zolowetsa mphamvu, mutha kusintha mawonekedwe amkati a coupler ndi detector, chonde funsani malonda poyitanitsa.
2 * Poika dongosolo, chonde tchulani kutalika kwa mawonekedwe ogwirira ntchito, omwe amayenera kukonzedwa molingana ndi kutalika kwa ntchito.
3 * kusintha kwa kutha kwa chiŵerengero kumadaliranso kusintha kwa chiŵerengero cha kutha kwa modulator yokha.
Kujambula kukula (mm)

1 Polar zimadalira dongosolo RF chizindikiro. Pamene palibe chizindikiro cha RF mu dongosolo, polar iyenera kukhala yabwino. Chizindikiro cha RF chikakhala ndi matalikidwe okulirapo kuposa mulingo wina, polar imasintha kuchoka ku zabwino kukhala zoyipa. Panthawiyi, Null point ndi Peak point zidzasinthana wina ndi mzake.Q + point ndi Q-point idzasinthananso. Kusintha kwa polar kumathandiza wogwiritsa ntchito kusintha polar.
mwachindunji popanda kusintha mfundo ntchito.
2Chisankho chimodzi chokha chidzasankhidwa pakati pa kugwiritsa ntchito photodiode yowongolera kapena kugwiritsa ntchito modulator photodiode. Ndibwino kuti mugwiritse ntchito photodiode yowongolera pazoyeserera za Lab pazifukwa ziwiri. Choyamba, chowongolera photodiode chatsimikizira mikhalidwe. Kachiwiri, ndi kosavuta kusintha athandizira kuwala intensity.Ngati ntchito modulator mkati photodiode, chonde onetsetsani kuti linanena bungwe panopa photodiode mosamalitsa molingana ndi athandizira mphamvu.
Rofea Optoelectronics imapereka mzere wazogulitsa zama Electro-optic modulators, Phase modulators, Intensity modulator, Photodetectors, Laser light sources, DFB lasers, Optical amplifiers, EDFA, SLD laser, QPSK modulation, Pulse laser, Light detector, Balanced driver photodetector, Laser , Fiber optic amplifier, Optical power mita, Broadband laser, Tunable laser, Optical detector, Laser diode driver, Fiber amplifier. Timaperekanso ma modulators ambiri osinthira makonda, monga 1 * 4 array phase modulators, Ultra-low Vpi, ndi Ultra-high extinction ratio modulators, omwe amagwiritsidwa ntchito m'mayunivesite ndi m'masukulu.
