Ultra Compact DP-IQ Modulator Bias Controller Automatic Bias Controller
Mbali
•Panthawi yomweyo amapereka ma voltages asanu ndi limodzi odziyimira pawokha a Dual Polarization IQ modulators
•Modulation format palokha:
SSB, QPSK, QAM, OFDM yatsimikiziridwa.
•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) × 29mm(D) ×8mm(H)
•Kukhazikika kwakukulu: Kugwiritsa ntchito digito kwathunthu Kusavuta kugwiritsa ntchito:
•Kugwiritsa ntchito pamanja ndi mini jumper 2
Ntchito zosinthika za OEM kudzera mu UART /IO
• Njira ziwiri zoperekera ma voltages a tsankho: a.Automatic Bias Control b.User defined bias voltage
Kugwiritsa ntchito
•LiNbO3 ndi ma modulators ena a DP-IQ
•Kutumiza Mogwirizana
