Ultra Compact IQ Modulator Bias Controller Automatic Bias Controller
Mbali
•Imapereka zokondera zitatu za ma IQ modulators mtundu wodziyimira pawokha:
•QPSK, QAM, OFDM, SSB zatsimikiziridwa
•Pulagi ndi Sewerani:
Palibe kusanja pamanja komwe kumafunikira Chilichonse chodziwikiratu
•Ine, Q arms: kuwongolera pa Peak ndi Null Kutha kwakukulu: 50dB max1
•P mkono: controll pa Q+ ndi Q- modes Kulondola: ± 2◦
Kutsika: 40mm(W) × 28mm(D) × 8mm(H)
•Kukhazikika kwakukulu: Kugwiritsa ntchito digito kwathunthu Kusavuta kugwiritsa ntchito:
•Kugwiritsa ntchito pamanja ndi mini jumper Flexible OEM ntchito kudzera mu UART2
• Njira ziwiri zoperekera ma voltages a tsankho: a.Automatic Bias Control b.User defined bias voltage
Kugwiritsa ntchito
•LiNbO3 ndi ma IQmodulators ena
•QPSK, QAM, OFDM, SSB ndi zina
•Kutumiza Mogwirizana

1. MER ikutanthauza Modulator Extinction Ratio. Chiyerekezo cha kuzimiririka chomwe chimapezedwa nthawi zambiri ndi chiwopsezo cha kutha kwa ma module omwe amatchulidwa mu datasheet ya modulator.
2. Chonde dziwani kuti kuyika kwamphamvu kwa kuwala sikufanana ndi mphamvu ya kuwala pa malo osankhidwa osankhidwa. Zimatanthawuza mphamvu yochuluka ya kuwala yomwe modulator imatha kutumiza kwa wolamulira pamene voteji ya bias imachokera ku −Vπ mpaka + Vπ.

1 Polar zimadalira dongosolo RF chizindikiro. Pamene palibe chizindikiro cha RF mu dongosolo, polar iyenera kukhala yabwino. Chizindikiro cha RF chikakhala ndi matalikidwe akulu 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 ma Ultra-high extinction ratio modulators, omwe amagwiritsidwa ntchito m'mayunivesite ndi m'masukulu.
Tikukhulupirira kuti mankhwala athu adzakhala othandiza kwa inu ndi kafukufuku wanu.
