Chinhu
•Inopa rusaruro rutatu kune vanogadzirisa IQ. Maitiro ekushandura akazvimiririra:
•QPSK, QAM, OFDM, SSB yakasimbiswa
•Bata uye Tamba:
Hapana kudiwa kwekugadzirisa nemaoko Zvese zviri otomatiki
•I, Q arms: controll on Peak and Null modes High extinction ratio: 50dB max1
•P arm: controll paQ+ neQ- modes Kururama: ± 2◦
•Profile yakaderera: 40mm(W) × 28mm(D) × 8mm(H)
•Kugadzikana kwakanyanya: kushandiswa kwedhijitari zvizere Zviri nyore kushandisa:
•Kushanda nemaoko ne mini jumper Kushanda kweOEM inochinjika kuburikidza neUART2
•Maitiro maviri ekupa mavoltage ekubiridzira: a.Kudzora Bias otomatiki b.Voltage yekubiridzira yakatsanangurwa nemushandisi
Kushandiswa
•LiNbO3 nedzimwe IQmodulators
•QPSK, QAM, OFDM, SSB nezvimwewo
•Kutumira Kwakabatana

1 Polar inoenderana nechiratidzo cheRF chesystem. Kana pasina chiratidzo cheRF musystem, polar inofanira kunge yakanaka. Kana chiratidzo cheRF chine amplitude yakakura kupfuura imwe level, polar ichachinja kubva pane yakanaka kuenda kune negative. Panguva ino, Null point nePeak point zvichachinjana. Q+ point neQ- point zvichachinjana zvakare. Polar switch inobvumira mushandisi kuchinja polar
zvakananga pasina kuchinja nzvimbo dzekushanda.
2Sarudzo imwe chete ndiyo inofanira kusarudzwa pakati pekushandisa controller photodiode kana kushandisa modulator photodiode. Zvinokurudzirwa kushandisa controller photodiode pakuedza kweLab nekuda kwezvikonzero zviviri. Chekutanga, controller photodiode ine hunhu hwayo. Chechipiri, zviri nyore kugadzirisa simba rechiedza chinopinzwa. Kana uchishandisa photodiode yemukati memodulator, ndapota iva nechokwadi chekuti simba rekubuda kwephotodiode rinoenderana nesimba rinopinzwa.
Rofea Optoelectronics inopa mhando yezvigadzirwa zvema Electro-optic modulators ekutengesa, Phase modulators, Intensity modulator, Photodetectors, Laser light sources, DFB lasers, Optical amplifiers, EDFA, SLD laser, QPSK modulation, Pulse laser, Light detector, Balanced photodetector, Laser driver, Fiber optic amplifier, Optical power meter, Broadband laser, Tunable laser, Optical detector, Laser diode driver, Fiber amplifier. Tinopawo ma modulators akawanda ekugadzirisa, akadai se 1*4 array phase modulators, ultra-low Vpi, uye ultra-high extinction ratio modulators, anoshandiswa zvakanyanya mumayunivhesiti nemasangano.
Ndinovimba kuti zvigadzirwa zvedu zvichakubatsira iwe nekutsvaga kwako.
