1 Polar zvinoenderana nehurongwa RF chiratidzo.Kana pasina chiratidzo cheRF muhurongwa, iyo polar inofanirwa kuve yakanaka.Kana chiratidzo cheRF chine amplitude yakakura kupfuura imwe nhanho, iyo polar inoshanduka kubva kune yakanaka kuita yakaipa.Panguva ino, Null point uye Peak point ichachinjana.Q+ point neQ-point zvichachinja pamwe chete.Polar switch inoita kuti mushandisi achinje polar.
zvakananga pasina kuchinja nzvimbo dzekushanda.
2Sarudzo imwe chete ndiyo ichasarudzwa pakati pekushandisa controller photodiode kana kushandisa modulator photodiode.Zvinokurudzirwa kushandisa controller photodiode yeLab kuyedza nezvikonzero zviviri.Chekutanga, controller photodiode yakave nechokwadi hunhu.Chechipiri, zviri nyore kugadzirisa mwenje wekuisa intensity.Kana uchishandisa modulator yemukati photodiode, ndapota ita shuwa kuti inobuda ikozvino yephotodiode inonyatso kuenderana nekuisa simba.
Rofea Optoelectronics inopa mutsara wechigadzirwa chekutengesa Electro-optic modulators, Phase modulators, Intensity modulator, Photodetectors, Laser light sources, DFB lasers,Optical amplifiers, EDFA, SLD laser, QPSK modulation, Pulse laser, Chiedza detector, Balanced driver photodetector, Laser. , Fiber optic amplifier, Optical power meter, Broadband laser, Tunable laser, Optical detector, Laser diode driver, Fiber amplifier.Isu tinopawo akawanda ma modulator ekugadzirisa, akadai se 1 * 4 array phase modulators, Ultra-low Vpi, uye ekupedzisira-yepamusoro yekutsakatika ratio modulators, inonyanya kushandiswa mumayunivhesiti nemasangano.
Tariro kuti zvigadzirwa zvedu zvichabatsira iwe nekutsvaga kwako.
